I had a pull request like this on my project somewhat recently, thousands of files changed, the author seemed unsure of what exactly they added, and names suggested use of AI tools.

I think it's a cool use case for AI, for non-programmers to be able to customize open source software for themselves with AI tools (just hope it doesn't introduce a data loss bug or security vulnerability...) But obviously these tools as of today will make an absolute mess over time without a lot of guidance, and being a non-programmer makes it impossible to give it that guidance. I guess it's fine if the only user is the non-programmer and they're never gonna maintain it themselves, but sometimes they assume some of the code somewhere will somehow be useful for the project and so they open a pull request like this without realizing the insanity they're doing
