Speaking as someone who posts a lot of stuff like this, the question isn't "Do I use AI or not?" The question is, "Do I have time to deal with writing this up for public consumption or not?"

This was a relatively complicated post of the sort that we are lucky to get in any form, AI-assisted or otherwise. Does it meet my personal stylistic standards? No, it's too LLM-ish. Assuming I cared about the presentation at all -- which I don't always, but would here -- I wouldn't be able to stop myself from fixing that in the process of reviewing it. Is it the usual bucket of slop? Emphatically no.
