Like what precisely? Infosec twitter is gone, science twitter is long dead. Visiting my timeline in non-algorithmic mode yields a post from months ago. In algo mode it's just ads and rage-bait.
(It is absolutely true that a lot of creators hate AI, although I would argue that they have fair reasons to do so given the way AI is frequently presented / talked about / used. I find it unfortunate that everything remotely related to machine learning has now been rebranded as "AI", which leads people to reflexively dunk on tools that really aren't that much like the AI they have in their heads, but it's not their fault.)
It is a journey, I still miss so many people from Twitter and it took me/us years of building a specific community, which is now mostly gone, but I do see signs of that appearing on Bluesky.
