Tbh, some anti-tech ideas (essentially eloquently presenting steelmanned ideas I'd only had at the periphery of my mind). All their ideas which goes against the grain, that I find valuable. (Warning tho: there's a lot of dopey-ness, amateurishness, and ideas in the podcast that I don't agree with. It's not for everyone. But I've found a lot of value in it the last month of listening to it.)
