I'm not sure what you mean by "he literally can't and he literally doesn't" but he's got PHD in CompSci and did everything at Google in the past from writing complex code himself to managing small teams to managing huge teams.

Exactly what do you think he can't do?

Certainly he's well qualified to manage a team of a few thousand (?) AI people and understand what they are talking about and get the best out of them.

Like Batman he has the superpower of money. If he has gaps he can pay (or otherwise arrange) for someone with those skills to 1-1 coach him in them.

He's not trying to become a top researcher, he's trying to learn enough to understand what they are talking about and be able to make decisions around say what areas should be pursued.
