Is a flood of bad pull requests really destroying quality, or is it just stress-testing the filter that was always there? Open source was never pure — it survived bad code, duplicate issues, and abandoned projects long before AI. The difference is that maintainers now have AI tools to triage, categorize, and patch, which cuts wasted human effort. From a sustainability angle, that matters: less burned-out maintainer energy, fewer abandoned projects, less duplicated work. From an ecological perspective, this is like an invasive species that actually feeds the ecosystem. The slop is noise, not destruction. The quality bar still lives in review, not in rejection of new tools.
