Language is constantly evolving, particularly in some communities. Not everybody is ready for it at all times. I, for instance, cannot stand that my community is now constantly “cooking” or “cooked”, that people in it are “locked in” or “cracked.” I don’t like it, because the use of the words primarily signals membership of a group rather than one’s individuality.

Language is constantly evolving, particularly in some communities. Not everybody is ready for it at all times. I, for instance, cannot stand that my community is now constantly “cooking” or “cooked”, that people in it are “locked in” or “cracked.” I don’t like it, because the use of the words primarily signals membership of a group rather than one’s individuality.

But some of the changes to that language might now be coming from … machines? Or maybe not. I don’t know. I, like many others, noticed that some words keep showing up more than before, and the obvious assumption is that LLMs are at fault. What I did was take 90 days’ worth of my local coding sessions and look for medium-frequency words where their use is inflated compared to what wordfreq would assume their frequency should be. Then I looked for the more common of these words and did a Google Trends search (filtered to the US). Note that some words like “capability” are more likely going to show up in coding sessions just because of the nature of the problem, so the actual increase is much more pronounced than you would expect.

You can click through it; this is what the change over time looks like. Note that these are all words from agent output in my coding sessions that are inflated compared to historical norms:

Something is going on for sure. Google Trends, in theory, reflects words that people search for. In theory, maybe agents are doing some of the Googling, but it might just be humans Googling for stuff that is LLM-generated; I don’t know. This data set might be a complete fabrication, but for all the words I checked and selected, I also saw an increase on Google Trends.

So how did I select the words to check in the first place? First, I looked for the highest-frequency words. They were, as you would expect, things like “add”, “commit”, “patch”, etc. Then I had an LLM generate a word list of words that it thought were engineering-related, and I excluded them entirely from the list. Then I also removed the most common words to begin with. In the end, I ended up with the list above, plus some other ones that are internal project names. For instance, habitat and absurd , as well as some other internal code names, were heavily over-represented, and I had to remove those. As you can see, not entirely scientific. But of the resulting list of words with a high divergence compared to wordfreq, they all also showed spikes on Google Trends.

There might also be explanations other than LLM generation for what is going on, but I at least found it interesting that my coding session spikes also show up as spikes on Google Trends.

The Rise of LLM Slop

The choice of words is one thing; the way in which LLMs form sentences is another. It’s not hard to spot LLM-generated text, but I’m increasingly worried that I’m starting to write like an LLM because I just read so much more LLM text. The first time I became aware of this was that I used the word “substrate” in a talk I gave earlier this year. I am not sure where I picked it up, but I really liked it for what I wanted to express and I did not want to use the word “foundation”. Since then, however, I am reading this word everywhere. This, in itself, might be a case of the Baader–Meinhof phenomenon , but you can also see from the selection above that my coding agent loves substrate more than it should, and that Google Trends shows an increase.

We have all been exposed to LLM-generated text now, but I feel like this is getting worse recently. A lot of the tweet replies I get and some of the Hacker News comments I see read like they are LLM-generated, and that includes people I know are real humans. It’s really messing with my brain because, on the one hand, I really want to tell people off for talking and writing like LLMs; on the other hand, maybe we all are increasingly actually writing and speaking like LLMs?

I was listening to a talk recording recently (which I intentionally will not link) where the speaker used the same sentence structure that is over-represented in LLM-generated text. Yes, the speaker might have used an LLM to help him generate the talk, but at the same time, the talk sounded natural. So either it was super well-rehearsed, or it was natural.

Engage and Farm

At least on Twitter, LinkedIn, and elsewhere, there is a huge desire among people to write content and be read. Shutting up is no longer an option and, as a result, people try to get reach and build their profile by engaging with anything that is popular or trending. In the same way that everybody has gazillions of Open Source projects all of a sudden, everybody has takes on everything.

My inbox is a disaster of companies sending me AI-generated nonsense and I now routinely see AI-generated blog posts (or at least ones that look like they are AI-generated) being discussed in earnest on Hacker News and elsewhere.

Genuine human discourse had already been an issue because of social media algorithms before, but now it has become incredibly toxic. As more and more people discover that they can use LLMs to optimize their following, they are entering an arms race with the algorithms and real genuine human signal is losing out quickly. There are entire companies now that just exist to automate sending LLM-generated shit and people evidently pay money for it.

Speed Should Kill

If we take into account the idea that the highest-quality content should win out, then the speed element would not matter. If a human-generated comment comes in 15 minutes after a clanker-generated one, but outperforms it by being better, then this whole LLM nonsense would show up less. But I think that LLM-generated noise actually performs really well. We see this plenty with Open Source now. Someone builds an interesting project, puts it on GitHub and within hours, there are “remixes” and “reimplementations” of that codebase. Not only that, many of those forks come with sloppy marketing websites, paid-for domains, and a whole story on socials about why this is the path to take.

I have complained before that Open Source is quickly deteriorating because people now see the opportunity to build products on top of useful Open Source projects, but the underlying mechanics are the same as why we see so much LLM slop. Someone has a formed opinion (hopefully) at lunch, and then has a clanker-made post 3 minutes later. It just does not take that much time to build it. For the tweets, I think it’s worse because I suspect that some people have scripts running to mostly automate the engagement.

And surely, we should hate all of this. These low-effort posts, tweets, and Open Source projects should not make it anywhere. But they do! Whatever they play into, whether in the algorithms or with human engagement, they are not punished enough for how little effort goes into them.

Friction and Rate Limiting

That increases in speed and ease of access can turn into problems is a long-understood issue. ID cards are a very unpopular thing in the UK because the British are suspicious of misuse of a central database after what happened in Nazi Germany. Likewise the US has the Firearm Owners Protection Act from 1986, which also bans the US from creating a central database of gun owners. The gun-tracing methodologies that result from not having such a database look like something out of a Wes Anderson movie . We have known for a long time that certain things should not be easy, because of the misuse that happens.

We know it in engineering; we know it when it comes to governmental overreach. Now we are probably going to learn the same lesson in many more situations because LLMs make almost anything that involves human text much easier. This is hitting existing text-based systems quickly. Take, for instance, the EU complaints system, which is now buckling under the pressure of AI . Or take any AI-adjacent project’s issue tracker. Pi is routinely getting AI-generated issue requests, sometimes even without the knowledge of the author .

Trust Erosion and Gaslighting

I know that’s a lot of complaining for “I am getting too many emails, shitty Twitter mentions, and GitHub issues.” I really think, though, that now that we know that it’s happening, we have to change how we interact with people who are increasingly automating themselves. Not only do they produce a lot of shitty slop that we all have to sit through; they are also influencing the world in much more insidious ways, in that they are influencing our interactions with each other. The moment I start distrusting people I otherwise trust, because they have started picking up LLM phrasing, it erodes trust all over society.

You also can’t completely ban people for bad behavior, because some of this increasingly happens accidentally. You sending Polsia spam to me? You’re dead to me. You sending me an AI-generated issue request and following up with an apology five minutes later? Well, I guess mistakes happen. Yet, in many ways, what is going on and will continue to go on is unsettling.

I recently talked with my friend Ben who said he forced someone to call him to continue a conversation because he was no longer convinced he was talking to a human.

Not all of us have been exposed to the extreme cases of this yet, but I had a handful of interactions in which I questioned reality due to the behavior of the person on the other side. I struggle with this, and I consider myself to be pretty open to new technologies and AI in particular. But how will my children react to stuff like this? My mother? I have strong doubts that technology is going to solve this for us.

Suggestions for Change

The reason I don’t think technology is going to solve this for us is that while it can hide some spam and label some generated text, it won’t fix us humans. What is being damaged here are social interactions across the board: the assumption that when someone writes to you, there is a person on the other side who has put some care into the interaction. I would rather have someone ghost me or reject me than send me back some AI-generated slop.

Change has to start with awareness and an unfortunate development is that LLMs don’t just influence the text we read and they influence the text we write, even when we don’t use them. Given the resulting ambiguity, we need to become more aware of how easily we can turn into energy vampires when we use agents to back us up in interactions with others. Consider that every time someone reads text coming from you, they will increasingly have to make a judgment call if it was you, an LLM, or you and an LLM that produced the interaction. Transparency in either direction, when there is ambiguity, can help great lengths.

When someone sends us undeclared slop, we need to change how we engage with them. If we care about them, we should tell them. If we don’t care about them, we should not give them visibility and not engage.

When it comes to creating platforms and interfaces where text can be submitted, we need to throw more wrenches in. The fact that it was cheap for you to produce does not make it cheap for someone else to receive, and we need to find more creative ways to increase the backpressure. GitHub or whatever wants to replace it, will have a lot to improve here and some of which might be going against its core KPIs. More engagement is increasingly the wrong thing to look at if you want a long term healthy platform.

Whatever we can do to rate-limit social interactions is something we should try: more in-person meetings, more platforms where trust has to be earned, and maybe more acceptance that sometimes the right response is no response at all.

And as for AI assistance on this blog, I have an AI transparency disclaimer for a while. In this particular blog post I used Pi as an agent to help me generate the dynamic visualization and I used to write the code to analyze and scrape Google Trends.

Before GitHub

GitHub was not the first home of my Open Source software. SourceForge was.

GitHub was not the first home of my Open Source software. SourceForge was .

Before GitHub, I had my own Trac installation. I had Subversion repositories, tickets, tarballs, and documentation on infrastructure I controlled. Later I moved projects to Bitbucket, back when Bitbucket still felt like a serious alternative place for Open Source projects, especially for people who were not all-in on Git yet.

And then, eventually, GitHub became the place, and I moved all of it there.

It is hard for me to overstate how important GitHub became in my life. A large part of my Open Source identity formed there. Projects I worked on found users there. People found me there, and I found other people there. Many professional relationships and many friendships started because some repository, issue, pull request, or comment thread made two people aware of each other.

That is why I find what is happening to GitHub today so sad and so disappointing. I do not look at it as just the folks at Microsoft making product decisions I dislike. GitHub was part of the social infrastructure of Open Source for a very long time. For many of us, it was not merely where the code lived; it was where a large part of the community lived.

So when I think about GitHub’s decline, I also think about what came before it, and what might come after it. I have written a few times over the years about dependencies, and in particular about the problem of micro dependencies . In my mind, GitHub gave life to that phenomenon. It was something I definitely did not completely support, but it also made Open Source more inclusive. GitHub changed how Open Source feels, and later npm and other systems changed how dependencies feel. Put them together and you get a world in which publishing code is almost frictionless, consuming code is almost frictionless, and the number of projects in the world explodes.

That has many upsides. But it is worth remembering that Open Source did not always work this way.

A Smaller World

Before GitHub, Open Source was a much smaller world. Not necessarily in the number of people who cared about it, but in the number of projects most of us could realistically depend on.

There were well-known projects, maintained over long periods of time by a comparatively small number of people. You knew the names . You knew the mailing lists. You knew who had been around for years and who had earned trust. That trust was not perfect, and the old world had plenty of gatekeeping, but reputation mattered in a very direct way. We took pride (and got frustrated) when the Debian folks came and told us our licensing stuff was murky or the copyright headers were not up to snuff, because they packaged things up.

A dependency was not just a package name. It was a project with a history, a website, a maintainer, a release process, a lot of friction, and often a place in a larger community. You did not add dependencies casually, because the act of depending on something usually meant you had to understand where it came from.

Not all of this was necessarily intentional, but because these projects were comparatively large, they also needed to bring their own infrastructure. Small projects might run on a university server, and many of them were on SourceForge, but the larger ones ran their own show. They grouped together into larger collectives to make it work.

We Ran Our Own Infrastructure

My first Open Source projects lived on infrastructure I ran myself. There was a Trac installation, Subversion repositories, tarballs, documentation, and release files served from my own machines or from servers under my control. That was normal. If you wanted to publish software, you often also became a small-time system administrator. Georg and I ran our own collective for our Open Source projects: Pocoo . We shared server costs and the burden of maintaining Subversion and Trac, mailing lists and more.

Subversion in particular made this “running your own forge” natural. It was centralized: you needed a server, and somebody had to operate it. The project had a home, and that home was usually quite literal: a hostname, a directory, a Trac instance, a mailing list archive.

When Mercurial and Git arrived, they were philosophically the opposite. Both were distributed. Everybody could have the full repository. Everybody could have their own copy, their own branches, their own history. In principle, those distributed version control systems should have reduced the need for a single center. But despite all of this, GitHub became the center.

That is one of the great ironies of modern Open Source. The distributed version control system won, and then the world standardized on one enormous centralized service for hosting it.

What GitHub Gave Us

It is easy now to talk only about GitHub’s failures, of which there are currently many, but that would be unfair: GitHub was, and continues to be, a tremendous gift to Open Source.

It made creating a project easy and it made discovering projects easy. It made contributing understandable to people who had never subscribed to a development mailing list in their life. It gave projects issue trackers, pull requests, release pages, wikis, organization pages, API access, webhooks, and later CI. It normalized the idea that Open Source happens in the open, with visible history and visible collaboration. And it was an excellent and reasonable default choice for a decade.

But maybe the most underappreciated thing GitHub did was archival work: GitHub became a library. It became an index of a huge part of the software commons because even abandoned projects remained findable. You could find forks, and old issues and discussions all stayed online. For all the complaints one can make about centralization, that centralization also created discoverable memory. The leaders there once cared a lot about keeping GitHub available even in countries that were sanctioned by the US.

I know what the alternative looks like, because I was living it. Some of my earliest Open Source projects are technically still on PyPI , but the actual packages are gone. The metadata points to my old server, and that server has long stopped serving those files.

That was normal before the large platforms. A personal domain expired, a VPS was shut down, a developer passed away, and with them went the services they paid for. The web was once full of little software homes, and many of them are gone ¹ .

npm and the Dependency Explosion

The micro-dependency problem was not just that people published very small packages. The hosted infrastructure of GitHub and npm made it feel as if there was no cost to create, publish, discover, install, and depend on them.

In the pre-GitHub world, reputation and longevity were part of the dependency selection process almost by necessity, and it often required vendoring. Plenty of our early dependencies were just vendored into our own Subversion trees by default, in part because we could not even rely on other services being up when we needed them and because maintaining scripts that fetched them, in the pre-API days, was painful. The implied friction forced some reflection, and it resulted in different developer behavior. With npm-style ecosystems, the package graph can grow faster than anybody’s ability to reason about it.

The problem that this type of thinking created also meant that solutions had to be found along the way. GitHub helped compensate for the accountability problem and it helped with licensing. At one point, the newfound influx of developers and merged pull requests left a lot of open questions about what the state of licenses actually was. GitHub even attempted to rectify this with their terms of service.

The thinking for many years was that if I am going to depend on some tiny package, I at least want to see its repository. I want to see whether the maintainer exists, whether there are issues, whether there were recent changes, whether other projects use it, whether the code is what the package claims it is. GitHub became part of the system that provides trust, and more recently it has even become one of the few systems that can publish packages to npm and other registries with trusted publishing.

That means when trust in GitHub erodes, the problem is not isolated to source hosting. It affects the whole supply chain culture that formed around it.

GitHub Is Slowly Dying

GitHub is currently losing some of what made it feel inevitable. Maybe that’s just the life and death of large centralized platforms: they always disappoint eventually. Right now people are tired of the instability, the product churn, the Copilot AI noise, the unclear leadership, and the feeling that the platform is no longer primarily designed for the community that made it valuable.

Obviously, GitHub also finds itself in the midst of the agentic coding revolution and that causes enormous pressure on the folks over there. But the site has no leadership! It’s a miracle that things are going as well as they are.

For a while, leaving GitHub felt like a symbolic move mostly made by smaller projects or by people with strong views about software freedom. I definitely cringed when Zig moved to Codeberg! But I now see people with real weight and signal talking about leaving GitHub. The most obvious one is Mitchell Hashimoto, who announced that Ghostty will move . Where it will move is not clear, but it’s a strong signal. But there are others, too. Strudel moved to Codeberg and so did Tenacity . Will they cause enough of a shift? Probably not, but I find myself on non-GitHub properties more frequently again compared to just a year ago.

One can argue that this is good: it is healthy for Open Source to stop pretending that one company should be the default home of everything. Git itself was designed for a world with many homes.

Dispersion Has a Cost

Going back to many forges, many servers, many small homes, and many independent communities will increase decentralization, and in many ways it will force systems to adapt. This can restore autonomy and make projects less dependent on the whims of Microsoft leadership. It can also allow different communities to choose different workflows. What’s happening in Pi ‘s issue tracker currently is largely a result of GitHub’s product choices not working in the present-day world of Open Source. It was built for engagement, not for maintainer sanity.

It can also make the web forget again. I quite like software that forgets because it has a cleansing element. Maybe the real risk of loss will make us reflect more on actually taking advantage of a distributed version control system.

But if projects move to something more akin to self-hosted forges, to their own self-hosted Mercurial or cgit servers, we run the risk of losing things that we don’t want to lose. The code might be distributed in theory, but the social context often is not. Issues, reviews, design discussions, release notes, security advisories, and old tarballs are fragile. They disappear much more easily than we like to admit. Mailing lists, which carried a lot of this in earlier years, have not kept up with the needs of today, and are largely a user experience disaster.

We Need an Archive

As much as I like the idea of things fading out of existence, we absolutely need libraries and archives.

Regardless of whether GitHub is here to stay or projects find new homes, what I would like to see is some public, boring, well-funded archive for Open Source software. Something with the power of an endowment or public funding to keep it afloat. Something whose job is not to win the developer productivity market but just to make sure that the most important things we create do not disappear.

The bells and whistles can be someone else’s problem, but source archives, release artifacts, metadata, and enough project context to understand what happened should be preserved somewhere that is not tied to the business model or leadership mood of a single company.

GitHub accidentally became that archive because it became the center of Open Source activity. Once that no longer holds, we should not assume some magic archival function will emerge or that GitHub will continue to function as such. We have already seen what happens when project homes are just personal servers and good intentions, and we have seen what happened to Google Code and Bitbucket.

I hope GitHub recovers, I really do, in part because a lot of history lives there and because the people still working on it inherited something genuinely important. But I no longer think it is responsible to let the continued memory of Open Source depend on GitHub remaining a healthy product.

The world before GitHub had more autonomy and more loss, and in some ways, we’re probably going to move back there, at least for a while. Whatever people want to start building next should try to keep the memory and lose the dependence. It should be easier to move projects, easier to mirror their social context, easier to preserve releases, and harder for one company’s drift to become a cultural crisis for everyone else.

I do not want to go back to the old web of broken tarball links and abandoned Trac instances. I also do not want Open Source to pretend that the last twenty years were normal or permanent. GitHub wrote a remarkable chapter of Open Source, and if that chapter is ending, the next one should learn from it and also from what came before.

Equity for Europeans

If you spend enough time in US business or finance conversations, one word keeps showing up: equity.

If you spend enough time in US business or finance conversations, one word keeps showing up: equity .

Coming from a German-speaking, central European background, I found it surprisingly hard to fully internalize what that word means. More than that, I find it very hard to talk with other Europeans about it. Worst of all it’s almost impossible to explain it in German without either sounding overly technical or losing an important part of the meaning.

This post is in English, but it is written mostly for readers in Germany, Austria, and Switzerland, and more broadly for people from continental Europe. I move between “German-speaking” and “continental European” a bit. They are not the same thing, of course, but many continental European countries share a civil-law background that differs sharply from the English common-law and equity tradition. The words differ by language and jurisdiction, but the conceptual gap I am interested in shows up in similar ways.

In US usage, the word “equity” appears everywhere:

• real estate: “build equity in your home”
• startups: “employees get equity”
• public markets: “equity investors”
• private deals: “take an equity stake”
• personal finance: “negative equity in a car”
• social policy: “diversity, equity, and inclusion”

If you try to translate this into German, you have to choose words. Of course we can say Eigenkapital , Beteiligung , Anteil , Vermögen , Nettovermögen , or sometimes Substanzwert . In narrow contexts, each can be correct, but none of them carries the full concept. I find that gap interesting, because language affects default behavior and how we think about things.

One Word, Shared Meanings

In the English language, “equity” often carries multiple things at once. I believe the following ones to be the most important ones:

1. A legal-fairness dimension: historically tied to equity in law
2. A financial-accounting dimension: residual value after debt
3. A cultural dimension: ownership as a path to wealth and agency

If you open Wikipedia, you will find many more distinct meanings of equity, but they all relate to much the same concept, just from different angles.

German, on the other hand, can express each of these layers precisely, including the subtleties within each, but it uses different words and there is no common, everyday umbrella word that naturally bundles all three.

When a concept has one short, reusable, positive word, people can move it across contexts very easily. When the concept is split into technical fragments, it tends to stay technical, and people do not necessarily think of these things as related at all in a continental European context.

How Equity Got Here

What is hard for Europeans to understand is how the financial meaning of equity appeared, because it did not appear out of nowhere. The word’s original meaning comes from fairness or impartiality, and it made it to modern English via Old French and Latin ( equité / aequitas ).

Historically, English law had separate traditions: common law courts and courts of equity (especially the Court of Chancery ). Equity in law was about fairness, conscience, and remedies where strict common law rules were too rigid. Take mortgages for instance: in older English practice, a mortgage could transfer title as security. Under strict common law, missing a deadline could mean losing the property entirely. Courts of equity developed the “ equity of redemption ”: a borrower could still redeem by paying what was owed.

That equitable interest became foundational for how ownership and claims were understood. In finance, equity came to mean not just a number, but a claim: the residual owner’s stake after prior claims are satisfied.

The European Split

German and continental European legal development took a different path. Civil law systems did not build the same separate institutional track of “equity courts” versus common law courts. Fairness principles absolutely exist, but inside the codified system, not as a parallel jurisdiction with its own language and mythology.

As a result, German vocabulary has many different words, and they are highly domain-specific. There are equivalents in other languages, and to some degree they exist in English too:

• company balance sheet: Eigenkapital
• ownership share: Beteiligung , Anteil
• unrealized asset value: stille Reserven
• household wealth: Vermögen , Nettovermögen
• investment action: Anlage , Investition
• residual net assets: Reinvermögen

This precision is useful for legal drafting and accounting. But it also means we have less of the shared mental package that many Americans get from “equity”: own a piece, carry risk, participate in upside, build wealth.

Schuld Is Not Just Debt

There is another linguistic oddity worth noting: in German, “Schuld” can mean both debt/liability and guilt, and I think that too has changed how we think about equity.

“Schuld” in everyday language makes debt feel more morally charged than it does in the US. Indebtedness is often framed as a burden, and it is not thought of as a tool at all.

US financial language, by contrast, often frames debt more instrumentally and pairs it with an explicit positive counterpart: equity. Equity is what is yours after debt, what can appreciate, what can be transferred, and what can give you control.

In American financial language, debt is not as morally burdened, and equity is more than the absence of debt: it is the positive claim on the balance sheet — ownership, optionality, control, and upside.

Practical Matters

If you grew up with German-speaking framing, many US statements around equity can sound ideological or naive. From a continental European lens, they can sound like imported jargon or hollow. But if we ignore the concept, we lose something practical:

• We discuss salaries in cash terms but under-discuss ownership.
• We treat employee participation as exotic instead of normal.
• We under-explain compounding and intergenerational transfer.
• We miss a language for talking about agency through ownership.

I am not saying German-speaking Europeans are incapable of this mindset. Obviously we are not. But we clearly tend to think about these things differently.

Normalize Equity

When you hear “equity,” it helps to think of it as a rightful stake. Historically, it is connected to fairness and the recognition of a claim where strict rules would be too rigid. Financially, it is the part that remains after prior obligations. Culturally, it is something that can grow into control, agency, and upside.

That is not a perfect definition, but it captures why the term is so sticky in American discourse. It combines a present claim with a future possibility. It is not just what remains after debt; it is the part that can grow, compound, and give you agency.

If Europeans want to talk more seriously about entrepreneurship, retirement, housing, and wealth building, we would benefit from a stronger everyday vocabulary for exactly this idea. We need a longing for equity so that ownership does not remain something for founders, lawyers, accountants, and wealthy families, but becomes a normal part of how people think about work, risk, and their future.

Not because we should imitate America, but because this mental model helps people make clearer decisions about ownership, incentives, and long-term agency. For Europe, that shift feels long overdue .

Whenever a new technology shows up, the conversation quickly splits into camps. There are the people who reject it outright, and there are the people who seem to adopt it with religious enthusiasm. For more than a year now, no topic has been more polarising than AI coding agents.

Whenever a new technology shows up, the conversation quickly splits into camps. There are the people who reject it outright, and there are the people who seem to adopt it with religious enthusiasm. For more than a year now, no topic has been more polarising than AI coding agents.

What I keep noticing is that a lot of the criticism directed at these tools is perfectly legitimate, but it often comes from people without a meaningful amount of direct experience with them. They are not necessarily wrong. In fact, many of them cite studies, polls and all kinds of sources that themselves spent time investigating and surveying. And quite legitimately they identified real issues: the output can be bad, the security implications are scary, the economics are strange and potentially unsustainable, there is an environmental impact, the social consequences are unclear, and the hype is exhausting.

But there is something important missing from that criticism when it comes from a position of non-use: it is too abstract.

There is a difference between saying “this looks flawed in principle” and saying “I used this enough to understand where it breaks, where it helps, and how it changes my work.” The second type of criticism is expensive. It costs time, frustration, and a genuine willingness to engage.

The enthusiast camp consists of true believers. These are the people who have adopted the technology despite its shortcomings, sometimes even because they enjoy wrestling with them. They have already decided that the tool is worth fitting into their lives, so they naturally end up forgiving a lot. They might not even recognize the flaws because for them the benefits or excitement have already won.

But what does the center look like? I consider myself to be part of the center: cautiously excited, but also not without criticism. By my observation though that center is not neutral in the way people imagine it to be. Its bias is not towards endorsement so much as towards engagement, because the middle ground between rejecting a technology outright and embracing it fully is usually occupied by people willing to explore it seriously enough to judge it.

Bias on Both Sides

The compositions of the groups of people in the discussions about new technology are oddly shaped because one side has paid the cost of direct experience and the other has not, or not to the same degree. That alone creates an asymmetry.

Take coding agents as an example. If you do not use them, or at least not for productive work, you can still criticize them on many grounds. You can say they generate sloppy code, that they lower your skills, etc. But if you have not actually spent serious time with them, then your view of their practical reality is going to be inherited from somewhere else. You will know them through screenshots, anecdotes, the most annoying users on Twitter, conference talks, company slogans, and whatever filtered back from the people who did use them. That is not nothing, but it is not the same as contact.

The problem is not that such criticism is worthless. The problem is that people often mistake non-use for neutrality. It is not. A serious opinion on a new language, framework, device, or way of working usually has some minimum buy-in. You have to cross a threshold of use before your criticism becomes grounded in the thing itself rather than in its reputation.

That threshold is inconvenient. It asks you to spend time on something that may not pay off, and to risk finding yourself at least partially won over. It is a lot to ask of people. But because that threshold exists, the measured middle is rarely populated by people who are perfectly indifferent to change. It is populated by people who were willing to move toward it enough in order to evaluate it properly.

Simultaneously, it’s important to remember that usage does not automatically create wisdom. The enthusiastic adopter might have their own distortions. They may enjoy the novelty, feel a need to justify the time they invested, or overgeneralize from the niche where the technology works wonderfully. They may simply like progress and want to be associated with it.

This is particularly visible with AI. There are clearly people who have decided that the future is here, all objections are temporary, and every workflow must now be rebuilt around agents. What makes AI weirder is that it’s such a massive shift in capabilities that has triggered a tremendous injection of money, and a meaningful number of adopters have bet their future on that technology.

So if one pole is uninformed abstraction and the other is overcommitted enthusiasm, then surely the center must sit right in the middle between them?

Engagement Is Not Endorsement

The center, I would argue, naturally needs to lean towards engagement. The reason is simple: a genuinely measured opinion on a new technology requires real engagement with it.

You do not get an informed view by trying something for 15 minutes, getting annoyed once, and returning to your previous tools. You also do not get it by admiring demos, listening to podcasts or discussing on social media. You have to use it enough to get past both the first disappointment and the honeymoon phase. Seemingly with AI tools, true understanding is not a matter of hours but weeks of investment.

That means the people in the center are selected from a particular group: people who were willing to give the thing a fair chance without yet assuming it deserved a permanent place in their lives.

That willingness is already a bias towards curiosity and experimentation which makes the center look more like adopters in behavior, because exploration requires use, but it does not make the center identical to enthusiasts in judgment.

This matters because from the perspective of the outright rejecter, all of these people can look the same. If someone spent serious time with coding agents, found them useful in some areas, harmful in others, and came away with a nuanced view, they may still be thrown into the same bucket as the person who thinks agents can do no wrong.

But those are not the same position at all. It’s important to recognize that engagement with those tools does not automatically imply endorsement or at the very least not blanket endorsement.

The Center Looks Suspicious

This is why discussions about new technology, and AI in particular feel so polarized. The actual center is hard to see because it does not appear visually centered. From the outside, serious exploration can look a lot like adoption.

If you map opinions onto a line, you might imagine the middle as the point equally distant from rejection and enthusiasm. But in practice that is not how it works. The middle is shifted toward the side of the people who have actually interacted with the technology enough to say something concrete about it. That does not mean the middle has accepted the adopter’s conclusion. It means the middle has adopted some of the adopter’s behavior, because investigation requires contact.

That creates a strange effect because the people with the most grounded criticism are often also adopters. I would argue some of the best criticism of coding agents right now comes from people who use them extensively. Take Mario : he created a coding agent, yet is also one of the most vocal voices of criticism in the space. These folks can tell you in detail how they fail and they can tell you where they waste time, where they regress code quality, where they need carefully designed tooling, where they only work well in some ecosystems, and where the whole thing falls apart.

But because those people kept using the tools long enough to learn those lessons, they can appear compromised to outsiders. And worse: if they continue to use them, contribute thoughts and criticism back, they are increasingly thrown in with the same people who are devoid of any criticism.

Failure Is Possible

This line of thinking could be seen as an inherent “pro-innovation bias.” That would be wrong, as plenty of technology deserves resistance. Many people are right to resist, and sometimes the people who never gave a technology a chance saw problems earlier than everyone else. Crypto is a good reminder: plenty of projects looked every bit as exciting as coding agents do now, and still collapsed when the economics no longer worked.

What matters here is a narrower point. The center is not biased towards novelty so much as towards contact with the thing that creates potential change. The middle ground is not between use and non-use, but between refusal and commitment and the people in the center will often look more like adopters than skeptics, not because they have already made up their minds, but because getting an informed view requires exploration.

If you want to criticize a new thing well, you first have to get close enough to dislike it for the right reasons. And for some technologies, you also have to hang around long enough to understand what, exactly, deserves criticism.

Today I’m very happy to share that Mario Zechner is joining Earendil .

First things first: I think you should read Mario’s post . This is his news more than it is ours, and he tells his side of it better than I could. What I want to do here is add a more personal note about why this matters so much to me, how the last months led us here, and why I am so excited to have him on board.

Last year changed the way many of us thought about software. It certainly changed the way I did. I spent much of 2025 building, probing, and questioning how to build software, and in many more ways what I want to do. If you are a regular reader of this blog you were along for the ride. I wrote a lot, experimented a lot, and tried to get a better sense for what these systems can actually do and what kinds of companies make sense to build around them. There was, and continues to be, a lot of excitement in the air, but also a lot of noise. It has become clear to me that it’s not a question of whether AI systems can be useful but what kind of software and human-machine interactions we want to bring into the world with them.

That is one of the reasons I have been so drawn to Mario’s work and approaches.

Pi is, in my opinion, one of the most thoughtful coding agents and agent infrastructure libraries in this space. Not because it is trying to be the loudest or the fastest, but because it is clearly built by someone who cares deeply about software quality, taste, extensibility, and design. In a moment where much of the industry is racing to ship ever more quickly, often at the cost of coherence and craft, Mario kept insisting on making something solid. That matters to me a great deal.

I have known Mario for a long time, and one of the things I admire most about him is that he does not confuse velocity with progress. He has a strong sense for what good tools should feel like. He cares about details. He cares about whether something is well made. And he cares about building in a way that can last. Mario has been running Pi in a rather unusual way. He exerts back-pressure on the issue tracker and the pull requests through OSS vacations and other means.

The last year has also made something else clearer to me: these systems are not only exciting, they are also capable of producing a great deal of damage. Sometimes that damage is obvious; sometimes it looks like low-grade degradation everywhere at once. More slop, more noise, more disingenuous emails in my inbox. There is a version of this future that makes people more distracted, more alienated, and less careful with one another.

That is not a future I want to help build.

At Earendil, Colin and I have been trying to think very carefully about what a different path might look like. That is a big part of what led us to Lefos .

Lefos is our attempt to build a machine entity that is more thoughtful and more deliberate by design. Not an agent whose main purpose is to make everything a little more efficient so that we can produce even more forgettable output, but one that can help people communicate with more care, more clarity, and joy.

Good software should not aim to optimize every minute of your life, but should create room for better and more joyful experiences, better relationships, and better ways of relating to one another. Especially in communication and software engineering, I think we should be aiming for more thought rather than more throughput. We should want tools that help people be more considerate, more present, and more human. If all we do is use these systems to accelerate the production of slop, we will have missed the opportunity entirely.

This is also why Mario joining Earendil feels so meaningful to me. Pi and Lefos come from different starting points. There was a year of distance collaboration, but they are animated by a similar instinct: that quality matters, that design matters, and that trust is earned through care rather than captured through hype.

I am very happy that Pi is coming along for the ride. Me and Colin care a lot about it, and we want to be good stewards of it. It has already played an important role in our own work over the last months, and I continue to believe it is one of the best foundations for building capable agents. We will have more to say soon about how we think about Pi’s future and its relationship to Lefos, but the short version is simple: we want Pi to continue to exist as a high-quality, open, extensible piece of software, and we want to invest in making that future real. As for our thoughts of Pi’s license, read more here and our company post here .

About five months ago I wrote about Absurd, a durable execution system we built for our own use at Earendil, sitting entirely on top of Postgres and Postgres alone. The pitch was simple: you don’t need a separate service, a compiler plugin, or an entire runtime to get durable workflows. You need a SQL file and a thin SDK.

About five months ago I wrote about Absurd , a durable execution system we built for our own use at Earendil, sitting entirely on top of Postgres and Postgres alone. The pitch was simple: you don’t need a separate service , a compiler plugin , or an entire runtime to get durable workflows. You need a SQL file and a thin SDK.

Since then we’ve been running it in production, and I figured it’s worth sharing what the experience has been like. The short version: the design held up, the system has been a pleasure to work with, and other people seem to agree.

A Quick Refresher

Absurd is a durable execution system that lives entirely inside Postgres. The core is a single SQL file ( absurd.sql ) that defines stored procedures for task management, checkpoint storage, event handling, and claim-based scheduling. On top of that sit thin SDKs (currently TypeScript , Python and an experimental Go one) that make the system ergonomic in your language of choice.

The model is straightforward: you register tasks, decompose them into steps, and each step acts as a checkpoint. If anything fails, the task retries from the last completed step. Tasks can sleep, wait for external events, and suspend for days or weeks. All state lives in Postgres.

If you want the full introduction, the original blog post covers the fundamentals. What follows here is what we’ve learned since.

What Changed

The project got multiple releases over the last five months. Most of the changes are things you’d expect from a system that people actually started depending on: hardened claim handling, watchdogs that terminate broken workers, deadlock prevention, proper lease management, event race conditions, and all the edge cases that only show up when you’re running real workloads.

A few things worth calling out specifically.

Decomposed steps. The original design only had ctx.step() , where you pass in a function and get back its checkpointed result. That works well for many cases but not all. Sometimes you need to know whether a step already ran before deciding what to do next. So we added beginStep() / completeStep() , which give you a handle you can inspect before committing the result. This turned out to be very useful for modeling intentional failures and conditional logic. This in particular is necessary when working with “before call” and “after call” type hook APIs.

Task results. You can now spawn a task, go do other things, and later come back to fetch or await its result. This sounds obvious in hindsight, but the original system was purely fire-and-forget. Having proper result inspection made it possible to use Absurd for things like spawning child tasks from within a parent workflow and waiting for them to finish. This is particularly useful for debugging with agents too.

absurdctl . We built this out as a proper CLI tool. You can initialize schemas, run migrations, create queues, spawn tasks, emit events, retry failures from the command line. It’s installable via uvx or as a standalone binary. This has been invaluable for debugging production issues. When something is stuck, being able to just absurdctl dump-task --task-id=<id> and see exactly where it stopped is a very different experience from digging through logs.

Habitat . A small Go application that serves up a web dashboard for monitoring tasks, runs, checkpoints, and events. It connects directly to Postgres and gives you a live view of what’s happening. It’s simple, but it’s the kind of thing that makes the system more enjoyable for humans.

Agent integration. Since Absurd was originally built for agent workloads, we added a bundled skill that coding agents can discover and use to debug workflow state via absurdctl . There’s also a documented pattern for making pi agent turns durable by logging each message as a checkpoint.

What Held Up

The thing I’m most pleased about is that the core design didn’t need to change all that much. The fundamental model of tasks, steps, checkpoints, events, and suspending is still exactly what it was initially. We added features around it, but nothing forced us to rethink the basic abstractions.

Putting the complexity in SQL and keeping the SDKs thin turned out to be a genuinely good call. The TypeScript SDK is about 1,400 lines. The Python SDK is about 1,900 but most of this comes from the complexity of supporting colored functions. Compare that to Temporal’s Python SDK at around 170,000 lines. It means the SDKs are easy to understand, easy to debug, and easy to port. When something goes wrong, you can read the entire SDK in an afternoon and understand what it does.

The checkpoint-based replay model also aged well. Unlike systems that require deterministic replay of your entire workflow function, Absurd just loads the cached step results and skips over completed work. That means your code doesn’t need to be deterministic outside of steps. You can call Math.random() or datetime.now() in between steps and things still work, because only the step boundaries matter. In practice, this makes it much easier to reason about what’s safe and what isn’t.

Pull-based scheduling was the right choice too. Workers pull tasks from Postgres as they have capacity. There’s no coordinator, no push mechanism, no HTTP callbacks. That makes it trivially self-hostable and means you don’t have to think about load management at the infrastructure level.

What Might Not Be Optimal

I had some discussions with folks about whether the right abstraction should have been a durable promise . It’s a very appealing idea, but it turns out to be much more complex to implement in practice. It’s however in theory also more powerful. I did make some attempts to see what absurd would look like if it was based on durable promises but so far did not get anywhere with it. It’s however an experiment that I think would be fun to try!

What We Use It For

The primary use case is still agent workflows. An agent is essentially a loop that calls an LLM, processes tool results, and repeats until it decides it’s done. Each iteration becomes a step, and each step’s result is checkpointed. If the process dies on iteration 7, it restarts and replays iterations 1 through 6 from the store, then continues from 7.

But we’ve found it useful for a lot of other things too. All our crons just dispatch distributed workflows with a pre-generated deduplication key from the invocation. We can have two cron processes running and they will only trigger one absurd task invocation. We also use it for background processing that needs to survive deploys. Basically anything where you’d otherwise build your own retry-and-resume logic on top of a queue.

What’s Still Missing

Absurd is deliberately minimal, but there are things I’d like to see.

There’s no built-in scheduler. If you want cron-like behavior, you run your own scheduler loop and use idempotency keys to deduplicate. That works, and we have a documented pattern for it , but it would be nice to have something more integrated.

There’s no push model. Everything is pull. If you need an HTTP endpoint to receive webhooks and wake up tasks, you build that yourself. I think that’s the right default as push systems are harder to operate and easier to overwhelm but there are cases where it would be convenient. In particular there are quite a few agentic systems where it would be super nice to have webhooks natively integrated (wake on incoming POST request). I definitely don’t want to have this in the core, but that sounds like the kind of problem that could be a nice adjacent library that builds on top of absurd.

The biggest omission is that it does not support partitioning yet. That’s unfortunate because it makes cleaning up data more expensive than it has to be. In theory supporting partitions would be pretty simple. You could have weekly partitions and then detach and delete them when they expire. The only thing that really stands in the way of that is that Postgres does not have a convenient way of actually doing that.

The hard part is not partitioning itself, it’s partition lifecycle management under real workloads. If a worker inserts a row whose expires_at lands in a month without a partition, the insert fails and the workflow crashes. So you need a separate maintenance loop that always creates future partitions far enough ahead for sleeps/retries, and does that for every queue.

On the delete side, the safe approach is DETACH PARTITION CONCURRENTLY , but getting that to run from pg_cron doesn’t work because it cannot be run within a transaction, but pg_cron runs everything in one.

I don’t think it’s an unsolvable problem, but it’s one I have not found a good solution for and I would love to get input on .

Does Open Source Still Matter?

This brings me a bit to a meta point on the whole thing which is what the point of Open Source libraries in the age of agentic engineering is. Durable Execution is now something that plenty of startups sell you. On the other hand it’s also something that an agent would build you and people might not even look for solutions any more. It’s kind of … weird?

I don’t think a durable execution library can support a company, I really don’t. On the other hand I think it’s just complex enough of a problem that it could be a good Open Source project void of commercial interests. You do need a bit of an ecosystem around it, particularly for UI and good DX for debugging, and that’s hard to get from a throwaway implementation.

I don’t think we have squared this yet, but it’s already much better to use than a few months ago.

If you’re using Absurd, thinking about it, or building adjacent ideas, I’d love your feedback. Bug reports, rough edges, design critiques, and contributions are all very welcome—this project has gotten better every time someone poked at it from a different angle.

Some Things Just Take Time

Trees take quite a while to grow. If someone 50 years ago planted a row of oaks or a chestnut tree on your plot of land, you have something that no amount of money or effort can replicate. The only way is to wait. Tree-lined roads, old gardens, houses sheltered by decades of canopy: if you want to start fresh on an empty plot, you will not be able to get that.

Trees take quite a while to grow. If someone 50 years ago planted a row of oaks or a chestnut tree on your plot of land, you have something that no amount of money or effort can replicate. The only way is to wait. Tree-lined roads, old gardens, houses sheltered by decades of canopy: if you want to start fresh on an empty plot, you will not be able to get that.

Because some things just take time.

We know this intuitively. We pay premiums for Swiss watches, Hermès bags and old properties precisely because of the time embedded in them. Either because of the time it took to build them or because of their age. We require age minimums for driving, voting, and drinking because we believe maturity only comes through lived experience.

Yet right now we also live in a time of instant gratification, and it’s entering how we build software and companies. As much as we can speed up code generation, the real defining element of a successful company or an Open Source project will continue to be tenacity. The ability of leadership or the maintainers to stick to a problem for years, to build relationships, to work through challenges fundamentally defined by human lifetimes.

Friction Is Good

The current generation of startup founders and programmers is obsessed with speed. Fast iteration, rapid deployment, doing everything as quickly as possible. For many things, that’s fine. You can go fast, leave some quality on the table, and learn something along the way.

But there are things where speed is actively harmful, where the friction exists for a reason. Compliance is one of those cases. There’s a strong desire to eliminate everything that processes like SOC2 require, and an entire industry of turnkey solutions has sprung up to help — Delve just being one example, there are more.

There’s a feeling that all the things that create friction in your life should be automated away. That human involvement should be replaced by AI-based decision-making. Because it is the friction of the process that is the problem. When in fact many times the friction, or that things just take time, is precisely the point.

There’s a reason we have cooling-off periods for some important decisions in one’s life. We recognize that people need time to think about what they’re doing, and that doing something right once doesn’t mean much because you need to be able to do it over a longer period of time.

Vibe Slop At Inference Speeds

AI writes code fast which isn’t news anymore. What’s interesting is that we’re pushing this force downstream: we seemingly have this desire to ship faster than ever, to run more experiments and that creates a new desire, one to remove all the remaining friction of reviews, designing and configuring infrastructure, anything that slows the pipeline. If the machines are so great, why do we even need checklists or permission systems? Express desire, enjoy result.

Because we now believe it is important for us to just do everything faster. But increasingly, I also feel like this means that the shelf life of much of the software being created today — software that people and businesses should depend on — can be measured only in months rather than decades, and the relationships alongside.

In one of last year’s earlier YC batches, there was already a handful that just disappeared without even saying what they learned or saying goodbye to their customers. They just shut down their public presence and moved on to other things. And to me, that is not a sign of healthy iteration. That is a sign of breaking the basic trust you need to build a relationship with customers. A proper shutdown takes time and effort, and our current environment treats that as time not wisely spent. Better to just move on to the next thing.

This is extending to Open Source projects as well. All of a sudden, everything is an Open Source project, but many of them only have commits for a week or so, and then they go away because the motivation of the creator already waned. And in the name of experimentation, that is all good and well, but what makes a good Open Source project is that you think and truly believe that the person that created it is either going to stick with it for a very long period of time, or they are able to set up a strategy for succession, or they have created enough of a community that these projects will stand the test of time in one form or another.

My Time

Relatedly, I’m also increasingly skeptical of anyone who sells me something that supposedly saves my time. When all that I see is that everybody who is like me, fully onboarded into AI and agentic tools, seemingly has less and less time available because we fall into a trap where we’re immediately filling it with more things.

We all sell each other the idea that we’re going to save time, but that is not what’s happening. Any time saved gets immediately captured by competition. Someone who actually takes a breath is outmaneuvered by someone who fills every freed-up hour with new output. There is no easy way to bank the time and it just disappears.

I feel this acutely. I’m very close to the red-hot center of where economic activity around AI is taking place, and more than anything, I have less and less time, even when I try to purposefully scale back and create the space. For me this is a problem. It’s a problem because even with the best intentions, I actually find it very hard to create quality when we are quickly commoditizing software, and the machines make it so appealing.

I keep coming back to the trees. I’ve been maintaining Open Source projects for close to two decades now. The last startup I worked on, I spent 10 years at. That’s not because I’m particularly disciplined or virtuous. It’s because I or someone else, planted something, and then I kept showing up, and eventually the thing had roots that went deeper than my enthusiasm on any given day. That’s what time does! It turns some idea or plan into a commitment and a commitment into something that can shelter and grow other people.

Nobody is going to mass-produce a 50-year-old oak. And nobody is going to conjure trust, or quality, or community out of a weekend sprint. The things I value most — the projects, the relationships, the communities — are all things that took years to become what they are. No tool, no matter how fast, was going to get them there sooner.

We recently planted a new tree with Colin. I want it to grow into a large one. I know that’s going to take time, and I’m not in a rush.

AI And The Ship of Theseus

Because code gets cheaper and cheaper to write, this includes re-implementations. I mentioned recently that I had an AI port one of my libraries to another language and it ended up choosing a different design for that implementation. In many ways, the functionality was the same, but the path it took to get there was different. The way that port worked was by going via the test suite.

Because code gets cheaper and cheaper to write, this includes re-implementations. I mentioned recently that I had an AI port one of my libraries to another language and it ended up choosing a different design for that implementation. In many ways, the functionality was the same, but the path it took to get there was different. The way that port worked was by going via the test suite.

Something related, but different, happened with chardet . The current maintainer reimplemented it from scratch by only pointing it to the API and the test suite. The motivation: enabling relicensing from LGPL to MIT. I personally have a horse in the race here because I too wanted chardet to be under a non-GPL license for many years. So consider me a very biased person in that regard.

Unsurprisingly, that new implementation caused a stir. In particular, Mark Pilgrim, the original author of the library, objects to the new implementation and considers it a derived work. The new maintainer, who has maintained it for the last 12 years, considers it a new work and instructs his coding agent to do precisely that. According to author, validating with JPlag, the new implementation is distinct. If you actually consider how it works, that’s not too surprising. It’s significantly faster than the original implementation, supports multiple cores and uses a fundamentally different design.

What I think is more interesting about this question is the consequences of where we are. Copyleft code like the GPL heavily depends on copyrights and friction to enforce it. But because it’s fundamentally in the open, with or without tests, you can trivially rewrite it these days. I myself have been intending to do this for a little while now with some other GPL libraries. In particular I started a re-implementation of readline a while ago for similar reasons, because of its GPL license. There is an obvious moral question here, but that isn’t necessarily what I’m interested in. For all the GPL software that might re-emerge as MIT software, so might be proprietary abandonware.

For me personally, what is more interesting is that we might not even be able to copyright these creations at all. A court still might rule that all AI-generated code is in the public domain, because there was not enough human input in it. That’s quite possible, though probably not very likely.

But this all causes some interesting new developments we are not necessarily ready for. Vercel, for instance, happily re-implemented bash with Clankers but got visibly upset when someone re-implemented Next.js in the same way.

There are huge consequences to this. When the cost of generating code goes down that much, and we can re-implement it from test suites alone, what does that mean for the future of software? Will we see a lot of software re-emerging under more permissive licenses? Will we see a lot of proprietary software re-emerging as open source? Will we see a lot of software re-emerging as proprietary?

It’s a new world and we have very little idea of how to navigate it. In the interim we will have some fights about copyrights but I have the feeling very few of those will go to court, because everyone involved will actually be somewhat scared of setting a precedent.

In the GPL case, though, I think it warms up some old fights about copyleft vs permissive licenses that we have not seen in a long time. It probably does not feel great to have one’s work rewritten with a Clanker and one’s authorship eradicated. Unlike the Ship of Theseus , though, this seems more clear-cut: if you throw away all code and start from scratch, even if the end result behaves the same, it’s a new ship. It only continues to carry the name. Which may be another argument for why authors should hold on to trademarks rather than rely on licenses and contract law.

I personally think all of this is exciting. I’m a strong supporter of putting things in the open with as little license enforcement as possible. I think society is better off when we share, and I consider the GPL to run against that spirit by restricting what can be done with it. This development plays into my worldview. I understand, though, that not everyone shares that view, and I expect more fights over the emergence of slopforks as a result. After all, it combines two very heated topics, licensing and AI, in the worst possible way.

Historically, writing code was slower than reviewing code.

Historically, writing code was slower than reviewing code.

It might not have felt that way, because code reviews sat in queues until someone got around to picking it up. But if you compare the actual acts themselves, creation was usually the more expensive part. In teams where people both wrote and reviewed code, it never felt like “we should probably program slower.”

So when more and more people tell me they no longer know what code is in their own codebase, I feel like something is very wrong here and it’s time to reflect.

You Are Here

Software engineers often believe that if we make the bathtub bigger , overflow disappears. It doesn’t. OpenClaw right now has north of 2,500 pull requests open. That’s a big bathtub.

Anyone who has worked with queues knows this: if input grows faster than throughput, you have an accumulating failure. At that point, backpressure and load shedding are the only things that retain a system that can still operate.

If you have ever been in a Starbucks overwhelmed by mobile orders, you know the feeling. The in-store experience breaks down. You no longer know how many orders are ahead of you. There is no clear line, no reliable wait estimate, and often no real cancellation path unless you escalate and make noise.

That is what many AI-adjacent open source projects feel like right now. And increasingly, that is what a lot of internal company projects feel like in “AI-first” engineering teams, and that’s not sustainable. You can’t triage, you can’t review, and many of the PRs cannot be merged after a certain point because they are too far out of date. And the creator might have lost the motivation to actually get it merged.

There is huge excitement about newfound delivery speed, but in private conversations, I keep hearing the same second sentence: people are also confused about how to keep up with the pace they themselves created.

We Have Been Here Before

Humanity has been here before. Many times over. We already talk about the Luddites a lot in the context of AI, but it’s interesting to see what led up to it. Mark Cartwright wrote a great article about the textile industry in Britain during the industrial revolution. At its core was a simple idea: whenever a bottleneck was removed, innovation happened downstream from that. Weaving sped up? Yarn became the constraint. Faster spinning? Fibre needed to be improved to support the new speeds until finally the demand for cotton went up and that had to be automated too. We saw the same thing in shipping that led to modern automated ports and containerization.

As software engineers we have been here too. Assembly did not scale to larger engineering teams, and we had to invent higher level languages. A lot of what programming languages and software development frameworks did was allow us to write code faster and to scale to larger code bases. What it did not do up to this point was take away the core skill of engineering.

While it’s definitely easier to write C than assembly, many of the core problems are the same. Memory latency still matters, physics are still our ultimate bottleneck, algorithmic complexity still makes or breaks software at scale.

Giving Up?

When one part of the pipeline becomes dramatically faster, you need to throttle input. Pi is a great example of this. PRs are auto closed unless people are trusted. It takes OSS vacations . That’s one option: you just throttle the inflow. You push against your newfound powers until you can handle them.

Or Giving In

But what if the speed continues to increase? What downstream of writing code do we have to speed up? Sure, the pull request review clearly turns into the bottleneck. But it cannot really be automated. If the machine writes the code, the machine better review the code at the same time. So what ultimately comes up for human review would already have passed the most critical possible review of the most capable machine. What else is in the way? If we continue with the fundamental belief that machines cannot be accountable, then humans need to be able to understand the output of the machine. And the machine will ship relentlessly. Support tickets of customers will go straight to machines to implement improvements and fixes, for other machines to review, for humans to rubber stamp in the morning.

A lot of this sounds both unappealing and reminiscent of the textile industry. The individual weaver no longer carried responsibility for a bad piece of cloth. If it was bad, it became the responsibility of the factory as a whole and it was just replaced outright. As we’re entering the phase of single-use plastic software, we might be moving the whole layer of responsibility elsewhere.

I Am The Bottleneck

But to me it still feels different. Maybe that’s because my lowly brain can’t comprehend the change we are going through, and future generations will just laugh about our challenges. It feels different to me, because what I see taking place in some Open Source projects, in some companies and teams feels deeply wrong and unsustainable. Even Steve Yegge himself now casts doubts about the sustainability of the ever-increasing pace of code creation.

So what if we need to give in? What if we need to pave the way for this new type of engineering to become the standard? What affordances will we have to create to make it work? I for one do not know. I’m looking at this with fascination and bewilderment and trying to make sense of it.

Because it is not the final bottleneck. We will find ways to take responsibility for what we ship, because society will demand it. Non-sentient machines will never be able to carry responsibility, and it looks like we will need to deal with this problem before machines achieve this status. Regardless of how bizarre they appear to act already.

I too am the bottleneck now . But you know what? Two years ago, I too was the bottleneck. I was the bottleneck all along. The machine did not really change that. And for as long as I carry responsibilities and am accountable, this will remain true. If we manage to push accountability upwards, it might change, but so far, how that would happen is not clear.

A Language For Agents

Last year I first started thinking about what the future of programming languages might look like now that agentic engineering is a growing thing. Initially I felt that the enormous corpus of pre-existing code would cement existing languages in place but now I’m starting to think the opposite is true. Here I want to outline my thinking on why we are going to see more new programming languages and why there is quite a bit of space for interesting innovation. And just in case someone wants to start building one, here are some of my thoughts on what we should aim for!

Why New Languages Work

Does an agent perform dramatically better on a language that it has in its weights? Obviously yes. But there are less obvious factors that affect how good an agent is at programming in a language: how good the tooling around it is and how much churn there is.

Zig seems underrepresented in the weights (at least in the models I’ve used) and also changing quickly. That combination is not optimal, but it’s still passable: you can program even in the upcoming Zig version if you point the agent at the right documentation. But it’s not great.

On the other hand, some languages are well represented in the weights but agents still don’t succeed as much because of tooling choices. Swift is a good example: in my experience the tooling around building a Mac or iOS application can be so painful that agents struggle to navigate it. Also not great.

So, just because it exists doesn’t mean the agent succeeds and just because it’s new also doesn’t mean that the agent is going to struggle. I’m convinced that you can build yourself up to a new language if you don’t want to depart everywhere all at once.

The biggest reason new languages might work is that the cost of coding is going down dramatically. The result is the breadth of an ecosystem matters less. I’m now routinely reaching for JavaScript in places where I would have used Python. Not because I love it or the ecosystem is better, but because the agent does much better with TypeScript.

The way to think about this: if important functionality is missing in my language of choice, I just point the agent at a library from a different language and have it build a port. As a concrete example, I recently built an Ethernet driver in JavaScript to implement the host controller for our sandbox. Implementations exist in Rust, C, and Go, but I wanted something pluggable and customizable in JavaScript. It was easier to have the agent reimplement it than to make the build system and distribution work against a native binding.

New languages will work if their value proposition is strong enough and they evolve with knowledge of how LLMs train. People will adopt them despite being underrepresented in the weights. And if they are designed to work well with agents, then they might be designed around familiar syntax that is already known to work well.

Why A New Language?

So why would we want a new language at all? The reason this is interesting to think about is that many of today’s languages were designed with the assumption that punching keys is laborious, so we traded certain things for brevity. As an example, many languages — particular modern ones — lean heavily on type inference so that you don’t have to write out types. The downside is that you now need an LSP or the resulting compiler error messages to figure out what the type of an expression is. Agents struggle with this too, and it’s also frustrating in pull request review where complex operations can make it very hard to figure out what the types actually are. Fully dynamic languages are even worse in that regard.

The cost of writing code is going down, but because we are also producing more of it, understanding what the code does is becoming more important. We might actually want more code to be written if it means there is less ambiguity when we perform a review.

I also want to point out that we are heading towards a world where some code is never seen by a human and is only consumed by machines. Even in that case, we still want to give an indication to a user, who is potentially a non-programmer, about what is going on. We want to be able to explain to a user what the code will do without going into the details of how.

So the case for a new language comes down to: given the fundamental changes in who is programming and what the cost of code is, we should at least consider one.

What Agents Want

It’s tricky to say what an agent wants because agents will lie to you and they are influenced by all the code they’ve seen. But one way to estimate how they are doing is to look at how many changes they have to perform on files and how many iterations they need for common tasks.

There are some things I’ve found that I think will be true for a while.

Context Without LSP

The language server protocol lets an IDE infer information about what’s under the cursor or what should be autocompleted based on semantic knowledge of the codebase. It’s a great system, but it comes at one specific cost that is tricky for agents: the LSP has to be running.

There are situations when an agent just won’t run the LSP — not because of technical limitations, but because it’s also lazy and will skip that step if it doesn’t have to. If you give it an example from documentation, there is no easy way to run the LSP because it’s a snippet that might not even be complete. If you point it at a GitHub repository and it pulls down individual files, it will just look at the code. It won’t set up an LSP for type information.

A language that doesn’t split into two separate experiences (with-LSP and without-LSP) will be beneficial to agents because it gives them one unified way of working across many more situations.

Braces, Brackets, and Parentheses

It pains me as a Python developer to say this, but whitespace-based indentation is a problem. The underlying token efficiency of getting whitespace right is tricky, and a language with significant whitespace is harder for an LLM to work with. This is particularly noticeable if you try to make an LLM do surgical changes without an assisted tool. Quite often they will intentionally disregard whitespace, add markers to enable or disable code and then rely on a code formatter to clean up indentation later.

On the other hand, braces that are not separated by whitespace can cause issues too. Depending on the tokenizer, runs of closing parentheses can end up split into tokens in surprising ways (a bit like the “strawberry” counting problem), and it’s easy for an LLM to get Lisp or Scheme wrong because it loses track of how many closing parentheses it has already emitted or is looking at. Fixable with future LLMs? Sure, but also something that was hard for humans to get right too without tooling.

Flow Context But Explicit

Readers of this blog might know that I’m a huge believer in async locals and flow execution context — basically the ability to carry data through every invocation that might only be needed many layers down the call chain. Working at an observability company has really driven home the importance of this for me.

The challenge is that anything that flows implicitly might not be configured. Take for instance the current time. You might want to implicitly pass a timer to all functions. But what if a timer is not configured and all of a sudden a new dependency appears? Passing all of it explicitly is tedious for both humans and agents and bad shortcuts will be made.

One thing I’ve experimented with is having effect markers on functions that are added through a code formatting step. A function can declare that it needs the current time or the database, but if it doesn’t mark this explicitly, it’s essentially a linting warning that auto-formatting fixes. The LLM can start using something like the current time in a function and any existing caller gets the warning; formatting propagates the annotation.

This is nice because when the LLM builds a test, it can precisely mock out these side effects — it understands from the error messages what it has to supply.

For instance:

fn issue(sub: UserId, scopes: []Scope) -> Token
    needs { time, rng }
{
    return Token{
        sub,
        exp: time.now().add(24h),
        scopes,
    }
}

test "issue creates exp in the future" {
    using time = time.fixed("2026-02-06T23:00:00Z");
    using rng  = rng.deterministic(seed: 1);

    let t = issue(user("u1"), ["read"]);
    assert(t.exp > time.now());
}

Results over Exceptions

Agents struggle with exceptions, they are afraid of them. I’m not sure to what degree this is solvable with RL (Reinforcement Learning), but right now agents will try to catch everything they can, log it, and do a pretty poor recovery. Given how little information is actually available about error paths, that makes sense. Checked exceptions are one approach, but they propagate all the way up the call chain and don’t dramatically improve things. Even if they end up as hints where a linter tracks which errors can fly by, there are still many call sites that need adjusting. And like the auto-propagation proposed for context data, it might not be the right solution.

Maybe the right approach is to go more in on typed results, but that’s still tricky for composability without a type and object system that supports it.

Minimal Diffs and Line Reading

The general approach agents use today to read files into memory is line-based, which means they often pick chunks that span multi-line strings. One easy way to see this fall apart: have an agent work on a 2000-line file that also contains long embedded code strings — basically a code generator. The agent will sometimes edit within a multi-line string assuming it’s the real code when it’s actually just embedded code in a multi-line string. For multi-line strings, the only language I’m aware of with a good solution is Zig, but its prefix-based syntax is pretty foreign to most people.

Reformatting also often causes constructs to move to different lines. In many languages, trailing commas in lists are either not supported (JSON) or not customary. If you want diff stability, you’d aim for a syntax that requires less reformatting and mostly avoids multi-line constructs.

Make It Greppable

What’s really nice about Go is that you mostly cannot import symbols from another package into scope without every use being prefixed with the package name. Eg: context.Context instead of Context . There are escape hatches (import aliases and dot-imports), but they’re relatively rare and usually frowned upon.

That dramatically helps an agent understand what it’s looking at. In general, making code findable through the most basic tools is great — it works with external files that aren’t indexed, and it means fewer false positives for large-scale automation driven by code generated on the fly (eg: sed , perl invocations).

Local Reasoning

Much of what I’ve said boils down to: agents really like local reasoning. They want it to work in parts because they often work with just a few loaded files in context and don’t have much spatial awareness of the codebase. They rely on external tooling like grep to find things, and anything that’s hard to grep or that hides information elsewhere is tricky.

Dependency Aware Builds

What makes agents fail or succeed in many languages is just how good the build tools are. Many languages make it very hard to determine what actually needs to rebuild or be retested because there are too many cross-references. Go is really good here: it forbids circular dependencies between packages (import cycles), packages have a clear layout, and test results are cached.

What Agents Hate

Macros

Agents often struggle with macros. It was already pretty clear that humans struggle with macros too, but the argument for them was mostly that code generation was a good way to have less code to write. Since that is less of a concern now, we should aim for languages with less dependence on macros.

There’s a separate question about generics and comptime . I think they fare somewhat better because they mostly generate the same structure with different placeholders and it’s much easier for an agent to understand that.

Re-Exports and Barrel Files

Related to greppability: agents often struggle to understand barrel files and they don’t like them. Not being able to quickly figure out where a class or function comes from leads to imports from the wrong place, or missing things entirely and wasting context by reading too many files. A one-to-one mapping from where something is declared to where it’s imported from is great.

And it does not have to be overly strict either. Go kind of goes this way, but not too extreme. Any file within a directory can define a function, which isn’t optimal, but it’s quick enough to find and you don’t need to search too far. It works because packages are forced to be small enough to find everything with grep.

The worst case is free re-exports all over the place that completely decouple the implementation from any trivially reconstructable location on disk. Or worse: aliasing.

Aliasing

Agents often hate it when aliases are involved. In fact, you can get them to even complain about it in thinking blocks if you let them refactor something that uses lots of aliases. Ideally a language encourages good naming and discourages aliasing at import time as a result.

Flaky Tests and Dev Env Divergence

Nobody likes flaky tests, but agents even less so. Ironic given how particularly good agents are at creating flaky tests in the first place. That’s because agents currently love to mock and most languages do not support mocking well. So many tests end up accidentally not being concurrency safe or depend on development environment state that then diverges in CI or production.

Most programming languages and frameworks make it much easier to write flaky tests than non-flaky ones. That’s because they encourage indeterminism everywhere.

Multiple Failure Conditions

In an ideal world the agent has one command, that lints and compiles and it tells the agent if all worked out fine. Maybe another command to run all tests that need running. In practice most environments don’t work like this. For instance in TypeScript you can often run the code even though it fails type checks . That can gaslight the agent. Likewise different bundler setups can cause one thing to succeed just for a slightly different setup in CI to fail later. The more uniform the tooling the better.

Ideally it either runs or doesn’t and there is mechanical fixing for as many linting failures as possible so that the agent does not have to do it by hand.

Will We See New Languages?

I think we will. We are writing more software now than we ever have — more websites, more open source projects, more of everything. Even if the ratio of new languages stays the same, the absolute number will go up. But I also truly believe that many more people will be willing to rethink the foundations of software engineering and the languages we work with. That’s because while for some years it has felt you need to build a lot of infrastructure for a language to take off, now you can target a rather narrow use case: make sure the agent is happy and extend from there to the human.

I just hope we see two things. First, some outsider art: people who haven’t built languages before trying their hand at it and showing us new things. Second, a much more deliberate effort to document what works and what doesn’t from first principles. We have actually learned a lot about what makes good languages and how to scale software engineering to large teams. Yet, finding it written down, as a consumable overview of good and bad language design, is very hard to come by. Too much of it has been shaped by opinion on rather pointless things instead of hard facts.

Now though, we are slowly getting to the point where facts matter more, because you can actually measure what works by seeing how well agents perform with it. No human wants to be subject to surveys, but agents don’t care . We can see how successful they are and where they are struggling.
