This is somewhat off-topic, but does Wolfram have a degenerative muscle illness? He puts his right hand down at around 30 minutes, and then doesn't move it again for hours. That and his unmoving legs are strikingly reminiscent of a friend who had MS.

He gestures with both his hands frequently throughout the entire video, not just before the 30 minute mark. I think this is just confirmation bias. And frankly, if he did have a degenerative muscle illness, that would be nobody’s business but his own.

That's fair, and you're entirely correct that its nobody's business but his own.
