Do you have more evidence than this? I'd honestly like to know.
I don't like AI slop like everybody else, but I'm also growing skeptical of the very fast determinations that sth is supposedly made by LLM just because it uses some phrase that Claude also uses. Models are trained on text written by human writers and if human text resembles it, this goes both ways. I have looked at the authors work from the pre-AI era and it reads similar to me.
So please, if you come with such a claim, please include what you base it on, so we all have a chance to determine how much to trust your verdict.
"every hour spent aligning with a co-author is an hour not spent producing output that is legible to an evaluation system." use of the word 'legible'.
"We defund the corridor and then wonder where the corridor conversations went." this is a claude-ist construction.
"This is an old worry wearing new clothes" this is a very claude-ist construction.
(rather ironically... as @embedding-shaep pointed out earlier): "Outsource the writing and you have not accelerated the thinking; you have skipped it." 'not X but punchy-Y' (not to be confused with 'not X but profound-Y'.
I'm not saying the author shouldn't have used an LLM - once in a while I suppose it gets used to good effect. But I wouldn't kid myself that the writing is certainly all human through-and-through.
[Incidentally, in case anyone's wondering where many of these claude-isms come from, just search within lesswrong.com .]
