Tom Scott very much seems like a workaholic and clearly has a passion for these types of videos. I'd be incredibly surprised if this were truly the end of his presence in YouTube rather than just the end of the current iteration of his channel.

Episodic deep dives would be lovely, it'd be really be fun to see that different pace of information from him. I always enjoy when he starts going on a tangent on the Lateral podcast, but he always catches himself for the sake of the show (to my slight disappointment at times.)
