This looks like a meme or attempt at a joke.

> Bun is the quintessential AI slop project at this point. Inheriting that is no easy task. I don’t think any human should sacrifice their sanity untangling this mess of 600K lines of slop code. For that reason, I will not be accepting any human-coded contributions until I deem the project to be in a sane enough shape. It will likely require most subsystems to be rewritten.

They're refusing to accept human-authored contributions. They're using LLMs to do the work. The author says they'll use LLMs to de-slop what they think is slop, and humans are banned from contributing.

I don't think you should take this seriously.
