> The weird looking part to he is cramming xAI into it. It's a completely different business with little overlap that I can see, in a crowded market that they are far from leading.

My personal theory is that Musk wants to roll up all his companies into a mega corporation that he fully controls, and this is part of the process. I expect Tesla and SpaceX to merge years down the line.

Of course, the counter to this thesis is that he didn't roll in Neuralink or Boring Company. But its probably that these three companies + Tesla are the ones he's most passionate about.
