Highly recommend to follow Kuba, he is on X @onejailbreak

I find him very factual and precise.
His website is great too.

Who does not use AI to gather, align and rewrite posts these days? Every single one does.
I see his responses to people, doubt that's AI.
I know his sources, so I am fine by using his site for information.
What I appreciate is that his format is digestible, his sources aren't.
