I'd also add: Tom Scott (basically the human version of Atlas Obscura) SmarterEveryDay (Former missile flight test engineer who does deep dives into science topics he's curious about) ThinMatrix (indie game developer who's building a custom game engine and game from the ground up) Adam Neely (music theory) Jan Misali (linguistics and obscura) Numberphile (math) PBS SpaceTime (physics) Simone Giertz (engineering) Journey to the Microcosmos (microbiology) Cody's Lab (all sorts of stuff, but he's currently in the multi-year process of building his own freaking Mars habitat) Ian Hubert (indie filmmaker who creates better work than most of hollywood, including absolutely massive CGI projects)
