"Open a PR on a popular repo today and observe what happens. Within seconds, a bot leaves an AI review summarizing your own change back to you. Another bot posts a preview deployment. Another posts a "walkthrough" with a sequence diagram nobody asked for. Sometimes a fourth shows up to respond to the third. By the time a human actually looks at it, the thread is a wall of generated text, and the real conversation (the human part) is buried somewhere in the middle.

That's the good case, where a human wrote the PR. The bad case is when nobody really did, like PRs that "fix" issues that don't exist, or PRs that rewrite half a file with confident, plausible, completely wrong code, or security reports that read like the real thing until you realize the vulnerability was hallucinated. And there are apparently accounts opening dozens of these a day across hundreds of repos, just farming green squares for a résumé.

I've started muting notifications from repos I used to love following since it's mostly just noise now, and that makes me sadder than I expected it to."
