Is there a transcript somewhere? Unless you're willing to pay me to throw away 40 minutes of my life listening to a stranger when it could have been an email
That said, you'd be missing a bunch of hand-made illustrations and animations from one of the best math communicators in the world. If that's not appealing to you, I'm not sure the transcript will do much for you either.
As it turns out, the only bits relevant to the title are the last five minutes of the video, and his contribution comes down to basically ignoring peoples' concerns and asserting that more technology means more joy. He conflates interest in math with a career in math and doesn't seem to address why actual mathematicians go into the field or what they get from it. In fact, the channel seems aimed at people who don't ever intend on going into the field.
If he doesn't grapple with the angst of turning an entire field of discourse into watching a chatbot beam-search a proof space, why make the video?
