Yeah, I originally joined dbzero because its an anarchist instance and I am an anarchist, but grew to dislike it cause of how pro-AI it is. So I swapped to slrpnk. But slrpnk is down and so I am stuck using dbzero till its back up.
I find it kinda wild that they are so pro-AI too cause all of the friends I have that are anarchists are varying degrees of anti-AI. Personally, I would be fine with AI if we lived in an anarchist society because no one would be negatively affected by it. However we don't, so there is only a very very small niche use case where you can use AI ethically. Otherwise I see it as scabbing. Being anti-copyright shouldn't mean walking all over artists and other creators.
"At The Cafe" by Errico Malasta and the documentary "Living In Utopia" which is on Zoe Baker's youtube channel were what made me hop the fence from being a council communist to an anarcho-communist. It was my starting point, so maybe it would be a good starting point for you. Pyotr Kropotkin is also a great source for anarchist theory, like "Conquest of Bread" and "Mutual Aid." If you want someone more recent then I hear Murray Bookchin is pretty good, although I haven't gotten around to reading anything by him yet. And as someone else mentioned, Anarchist Library is a great place to look for pretty much anything anarchist related. You'll likely find any of the books I mentioned there for free.
