For anyone interested in private space flight: Wild Wild Space documentary. Also a commentary about startups in general. Separately, I've been wondering how uneven human progress is. I think we have come a long way in electronics (relays to vacuum tubes to transistor to … to an M5 chip) but in some other domains, like moving objects through space, we are basically mostly reliant on thrust generated by burning fuel (EV's are a genuine advance, but mostly due to battery tech).
