They 100% got too much slop PRs. I can't speak for all OSS projects but in the case of Rust, it definitely got way out of hand. As a maintainer, there is no easy way to tell whether it was "AI code slop" or "closely human-guided agentic coding", you actually have to go in and understand the stuff. But making careless slop PRs takes 1% or less of the effort, and so the garbage PRs vastly outnumber everything else.

AI has ruined all of our previous signals for high-effort work, it is effectively running a sybil attack on FOSS.
