It was fascinating discovering this guy, I didn't know anything about him but I watched his series on algebraic topology bc I wanted to understand homology. Seemed like a good series, explained homology in a really intuitive way, but then I started watching his other stuff. It was mostly boring but made sense, but then he started saying some shit about real numbers not existing and it really made me sit up and listen. Glad he's out there questioning the foundations, I guess, and the equivalence class of sequences definition of real numbers definitely has a rigor problem, but there's a canonical choice of representative so it isn't really worth thinking about. What a crackpot.
