Will open source survive when agents can rebuild any package in seconds?

Alberto Arena asks whether open source still matters when an AI agent can generate a utility in 30 seconds, bypassing downloads, stars, and maintainer recognition. He cites matplotlib maintainer Tim Hoffmann's point that code generation is cheap but human review still falls on a few core developers. The piece argues that agents learn patterns from public READMEs, tests, and issue discussions—if no one writes those in the open, agents stagnate. Arena also notes that Roo Code shut down in May 2026, showing that teams trying to escape dependency on open-source projects often end up depending on a different, equally mortal tool.
