A couple that I haven’t seen yet: Foolish Baseball for a zillenial take on baseball, Hagerty, Throttle House and savagegeese for quality car YouTube and Scott Manley, BPS Space and Vintage Space for some good rocket science and history, and languagejones and Dr. Geoff Lindsey for linguistics.
We should crowdfund that! We could call it something clever… Like Soylent! :P
