I would imagine many people here who watch Youtube are already familiar with Folding Ideas, at least from his video about NFTs. He is imo the best video essayist by a wide mile.
Then there's Jenny Nicholson, her videos are hit or miss in the sense that I really don't care about most topics she talks about, but I find even those videos engaging and when she does talk about an interesting topic it's an all-timer for me.
