Ok. The music industry has an AI problem. I'm not anti-AI, but I'm pro-people. I don't ever want a track a person didn't perform to auto-play and infect my recommendations. It's so much more insidious and cynical than AI image gen because you can't opt-out. You support/fund them via auto-play.

I do not have a problem with AI, it's a tool. What I find fascinating is that in the case that AI removes the 'human connection', the value of its output, to me, falls to zero, or even less than zero for wasting my time. (We are social creatures, like it or not.)

The most 2026 question you can ask someone on a PR: "Sorry for asking, but are you a person or an AI agent?"

It's a sign of the times, that whenever a new open source project pops up, I instinctively and cynically check the commit history for evidence that this new library has just been vibe-coded and released into the wild.

Both these statements can be true at the same time: 1. AI slop is a burden for maintainers that were already suffering from burnout. 2. AI use can significantly lower the costs of maintaining open-source software.
