How Bluesky and Hacker News talk about AI-written code. Updated every 12 hours.
Ongoing research, not a verdict. These are my notes on how AI adoption is being discussed, compiled from posts on Bluesky and Hacker News. I mean them as a starting point for your own reading, especially as more projects introduce no-AI contribution policies to protect code quality.

No AI-generated code or documentation, no AI-written commit messages or PR descriptions, no AI review and no agents. Its policy says the copyright status of AI output is unclear under EU law. In place since 2025, clarified in March 2026.

What people actually said
Five posts from this week. AI-assisted, human-led. Cut, never reworded.
- The flood of low effort AI-contributions makes accepting anonymous contributions impractical nowadays. They'd waste hours reviewing things of no value. I know because it happened to several of my moderately successful projects. … I'm sure I will miss genuinely good and valuable contributions, but the signal-to-noise ratio is just too low.Hacker News · wary of AI · AI contributions ·Read on Hacker News ↗ (opens in a new tab)
- im on a somewhat large opensource project and we keep getting AI pull requests with 3k line additions and thankfully they helpfully list "passed (a different ai) code review". …Bluesky · wary of AI · AI code review ·Read on Bluesky ↗ (opens in a new tab)
- … can we please stop equating vibe-coding to AI-assisted coding? They are not the same thing. It's one thing to submit 5K vibe-coded untested PR and another thing to use AI to add functionality in a granular way that you can review, or generate boilerplate, or test your ideas and scrap them if they suck.Hacker News · neutral · Vibe coding ·Read on Hacker News ↗ (opens in a new tab)
- The main way we're using AI models is for code review and helping to write a lot more tests than we used to. It's helping to improve our code quality, not reducing it. … The code generated by even the bleeding edge publicly available frontier models is rarely good enough to meet our standards.Hacker News · open to AI · Vibe coding ·Read on Hacker News ↗ (opens in a new tab)
- From the interviews I've seen, Linus has complained a lot about the deluge of slop PRs flooding open source repos and only accepts PRs if the AI contributions are carefully vetted by their authors which seems like a pretty decent policyBluesky · mixed · AI contributions ·Read on Bluesky ↗ (opens in a new tab)
