Very likely AI slop, very hard to read. Too many indications. HN should have another rule: explicitly mention if article was written (primarily) by AI.
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.
I do not know how to say this another way. No. Nothing in this article was created, edited, outlined, pre-drafted, suggested, or in any other way influenced by AI. AI did not write the words, it did not review the words, it was not a part of a pre-writing discussion that influenced the words. There is NO AI IN THIS ARTICLE OR AS AN INPUT TO THIS ARTICLE. If the article is an apple, then 0% of the apple is AI or AI influenced.
And let this be a lesson to you. You apparently do not have any ability to distinguish between these two kinds of thing.
It doesn’t strike me as AI. The writing is reasonably information-dense and specific, logically coherent, a bit emotional. Rarely overconfident or vague. If it is AI then there was a lot more human effort put into refining it than most AI writing I’ve read.
