All right, I'm going to open up a history lesson because it's been a couple of generations of software engineers since this essay, and I have to assume not everyone knows what a cathedral is. Everyone knows what a bazaar is because they're using it day to day with GitHub.

GitHub took the bazaar's ideas—a decentralized, open, self-organizing open-source project—and provided a workflow that lets anyone inspect or contribute source code via a pull request.

I've been thinking that there needs to be a new software development model. We're not going back to the cathedral, where a small, private, exclusive group builds the source code, with releases that are heavily planned, infrequent, and polished.

But it's clear we need something else now that AI is here. The GitHub bazaar model, even before AI, was already showing its cracks because it created consumer-based entitlements where everyone was nagging maintainers to merge something. It created really weird social-structure expectations: that someone who releases code has an obligation to maintain it and get paid nothing for the work.

But now that AI is here, the dams have well and truly burst.

For what's the point of reading a pull request that's been generated by code? All I want is to read and understand the core idea. If it's a good idea, I might incorporate it back upstream, but there should be no expectation that I will.

You see, open source software is open source by definition because the license says that it's as is, and that as is permits you to remix software.

But the problem has been that it's been perceived as too hard to remix software, but it hasn't been. It's just a knowledge gap issue that no longer exists now that agents are here. Nix has existed for a long time. If you haven't seen the article that I posted a couple of days ago about Nix overlays, you should read it.

So, I'm going to propose something that I hope helps other open source maintainers. This is how I'm thinking about my software now that I release it under open-source licenses.

• Structure: Decentralized and compositional. Ideas spread through independent overlays rather than converging on a single repository and a single maintainer.
• Workflow: Publish source and intent under an as-is license. Others remix by writing a small Nix overlay that expresses the desired change once, then reuses that derivation across devenv shells, Docker images, NixOS systems and tests, CI, and agent sandboxes—without forking or maintaining a divergent artifact.
• Core Principle: Ideas over patches. The valuable unit is a change in behavior or architecture. Maintainers decide whether to incorporate it, reimplement it, or ignore it. The original author has no standing obligation to review, integrate, or maintain the change.
• Social Contract: The license already permits remixing without creating a claim on anyone’s future time. Credit and visibility can still exist; there is no ongoing maintenance duty. Upstream incorporation remains optional and deliberate.
• Discovery: Useful adaptations appear as a proliferation of overlays in the wild. Maintainers can sample from that spread if they choose; everyone else can grab and compose ideas simply by updating their own overlays via an agent.

Example: A consumer of a project wants to disable Git's ability to force push in that project. Instead of raising a pull request to the upstream project, the consumer makes an overlay that patches Git to refuse force pushes; this is defined once and then appears consistently in developer environments, container images, and system tests—without a pull request against the upstream project.

In practice, from this point forward, for any code I release on GitHub, I will disable pull requests, keep discussions open, and publish + maintain guidance on how you can remix my software.

The GitHub network graph provides a fantastic way to explore the remixes in the ecosystem. Heck, you can even run agents over it to summarize what people are doing. You can also use it in an agent loop to explore remix ideas and feed them back upstream into the main project.
