'Vibe Coding Kills Open Source'
13 102Four economists across Central European University, Bielefeld University and the Kiel Institute have built a general equilibrium model of the open-source software ecosystem and concluded that vibe coding -- the increasingly common practice of letting AI agents select, assemble and modify packages on a developer's behalf -- erodes the very funding mechanism that keeps open-source projects alive.
The core problem is a decoupling of usage from engagement. Tailwind CSS's npm downloads have climbed steadily, but its creator says documentation traffic is down about 40% since early 2023 and revenue has dropped close to 80%. Stack Overflow activity fell roughly 25% within six months of ChatGPT's launch. Open-source maintainers monetize through documentation visits, bug reports, and community interaction. AI agents skip all of that.
The model finds that feedback loops once responsible for open source's explosive growth now run in reverse. Fewer maintainers can justify sharing code, variety shrinks, and average quality falls -- even as total usage rises. One proposed fix is a "Spotify for open source" model where AI platforms redistribute subscription revenue to maintainers based on package usage. Vibe-coded users need to contribute at least 84% of what direct users generate, or roughly 84% of all revenue must come from sources independent of how users access the software.

I feel like the model described here is a minority of open source. I feel paid support contracts, source available, and corporations contributing to major projects is much more the norm.

AI is dumb, it cannot innovate. Without humans creating new training data, it will fall behind. AI must find a way to avoid being fatal to the host it feeds on.

Your post denies the status quo. That isn't how any of this works at all.
It's a distillation process. AI absolutely can (and is) being trained on AI-generated, AI-augmented, AI-processed, and AI-sintered data.
I'd suggest you familiarize yourself with where things are today (as opposed to 6 months ago, or 2 years ago). If you haven't reevaluated state of the art in the past 2 months with any depth, you're gravely behind.

It does seem that individual programmers would be much less likely to make their contributions to projects of all sizes available as open-source now that it's likely that those contributions will just be digested into an indistinguishable pap that will then be puked up by LLMs owned by oligarchic corporations. Because where's the satisfaction in that? Feels pretty demotivating to me.

This has nothing to do with "vibe coding".
I'm also unclear on what "documentation traffic" and "bug reports" has to do with a project earning money. Is this about seeing advertising? Because I'm not going to contribute to a project if that requires me to look at advertising.

"Open-source maintainers monetize through documentation visits"
Open source is monetized through documentation visits? Not only most open source programmers know how to use an adblocker, but I also saw very few (thanks god!) documentation pages with ads. What are these people talking about?

Bullshit. Stack Overflow does not have, and never had, a minimum reputation requirement for answering questions. You can create an account and immediately answer a question with 1 reputation (the starting default).
There is an exception for answering protected questions [stackoverflow.com] (of which there are an exceedingly small percentage). To answer a protected question you need 10 reputation, which corresponds to a single upvote.

If everybody is vibe coding and nobody is writing open source code anymore where does the innovation come from?
If you think about most success open source project, including Linux itself, they usually start small with people seeing them as a potential future solution to a problem they are working on or just something interesting to play with. They start slowly and grow in usability and interest increases. Eventually it becomes something truly useful and usage becomes widespread.
AI and vibe coding breaks that process at the early stages because there is no longer the humans looking at new things and taking a chance on something new and unfinished. Open source relies on people looking forward but AI can only look backwards. A future driven by vibe coding looks like it will free of innovation. Sounds boring to me.

Um... have you even tried vibe coding? You can one-shot a project in 20 minutes. I've done it numerous times - an old project I spent weeks writing specifications for, boom, done.
Have you even spent 5 seconds thinking about what you wrote here? If you need to spend weeks writing a specification and "vibe coding" it takes 20 minutes, it means you are either completely incompetent at writing specifications or your vibe-coded project simple doesn't do what you wrote in weeks. It's as simple as that.

It's more accurate to say that the entire concept of libraries and frameworks is now obsolete. Why bother building and maintaining libraries of tested code when you can just generate it from scratch every time? The only reason we used libraries was to keep things maintainable and reusable. If you can just get an LLM to generate bespoke code on demand, and have it do exactly what you want and nothing else, then every piece of software can be a snowflake... unique and fragile, but infinitely replaceable. It's a paradigm shift, that's for sure.

This paper reads like any one of dozens of papers I had to digest for game theory classes back in college. Granted, that was thirty years ago and “optimization theory” has replaced game theory in the course catalogs, but the bones are the same: Nash is still hiding under the floorboards, tapping out equilibria with a broom handle. What the authors are really doing here is describing a potential tragedy of the commons, and dressing it in modern clothing. In their setup, open source is the shared pasture: maintainers are the shepherds doing the unglamorous work of reseeding and mending fence lines, and users are the cows. Vibe coding adds a new kind of cow, one that grazes constantly and at scale while leaving fewer of the footprints that normally pay the shepherds back: attention, bug reports with reproduction steps, patches, docs corrections, donations, consulting leads, the whole informal economy that kept a lot of projects alive. If that return channel dries up, the equilibrium shifts: fewer shepherds bother staying out in the rain, the pasture degrades, and everyone ends up worse off even though the short-term output looks amazing.
Nothing about that is conceptually novel. What’s novel is the pressure profile. I watched Red Hat go from an interesting way to monetize Linux in 1994 to a $34B IBM acquisition a quarter century later, which tells you there’s real money in selling stability, support, and risk management around a free codebase. But this paper is pointing at a different failure mode: not “open source can’t be monetized,” but “open source can be consumed so efficiently that the incentives to maintain it get vacuumed away.” The paper’s real kicker is what they call the software-begets-software effect. We’ve all seen this: a healthy ecosystem of libraries makes building the next tool trivial. That’s a virtuous cycle that helped FOSS explode. But the authors’ math shows this loop has a reverse gear. If vibe coding starves maintainers of the attention currency they need to keep the lights on, the ecosystem doesn't just stagnate—it contracts. Entry falls, variety shrinks, and the cost of building new software starts to climb because the foundation is rotting. We’re essentially using AI to strip-mine the very topsoil we need for the next harvest.
The models in the paper may be a bit too tuned to represent all of FOSS, sure. But where they’re right, they’re right in the way you can't really argue against. If vibe coding siphons off funding, leaving some critical cluster of FOSS coders unwatered long enough, FOSS could be on a fast track to that tragedy of the commons.
