Semianalysis seem to have useful information but increasingly crazy extrapolations of trends and future predictions.
It's helpful to realize that Dylan (Semianalysis), Dwarkesh, Aschebrenner (the Situational Awareness guy) and Sholto Douglas (Anthropic) all share a house in SF, so what you are getting from any of them is the SF AI scene view of the world, which is interesting to know, but probably not the best predictor of how things are going to pan out.
