I'm the author. Literally 0% of this was written with AI. Not an outline, not the arguments, not a single word in any paragraph. We agonized over every aspect of this article: the wording, the structure, and in particular, about whether we were being fair to Yjs. We moved the second and third section around constantly. About a dozen people reviewed it and gave feedback.

EDIT: I will say I'm not against AI writing tools or anything like that. But, for better or worse, that's just not what happened here.
