I also watch and like that channel, it definitely has a bias and affinity, but IMO it is well researched and does a good job of explaining that perspective and the rationale behind it as opposed to just reciting talking points. I liked the most recent video about the threat of permanent dystopias, even though I don’t agree with some of the implicit assumptions it’s making about the nature of the problem (Rationalist stuff leans neoliberal). It’s fun and probably important to think about the long term future of humanity in an analytical way, sci-fi style.
