>>12459387TL;DR math foundations, and corresponding famous problems videos whenever appropriate.
Math Foundations, start at 1. When he references WildTrig when talking about geometry, watch that series (you can wait until afterwards as well). and potentially WildLinAlg. He also has some videos on algebraic geometry I think as well. But if you just want the high-level overview of stuff, math foundations is the way to go.
Also, he has a famous problems series so whenever you cover something in the math foundations series, be sure to check if there's a corresponding famous problems video for that as well.
Play at 2x speed (unless you're a complete math brainlet, in which case, play at 1x speed). His first videos will obviously be very basic since he starts from what natural numbers are, but I find his presentation really nice.
I personally came into his videos as a skeptic, but now at least acknowledge that finitism is a valid viewpoint. Will I abandon the reals? Probably not but I definitely don't think he is crank, just an extreme finitist with a strong opinion on things.
