I’ve been wondering this lately myself, and this is my conclusion. Not so much that he’s bored with Tesla, but that he’s through with it. It provided the cash for his real ambitions.
Reading all this stuff about the future the tech bros are trying to usher in, I think Musk is a bit different in his world view. He thinks that mankind is destined for the birth of a new era, a technological paradise that can only be brought on by rapid, unchecked progress. Maybe it’s a Mars colony, maybe it’s the AGI singularity, but he believes there will be some tipping point after which life for all humans will get better.
And he thinks that suffering will continue until we reach this point, therefore getting to that point is the most important thing humanity should be working towards. That end justifies any means.
This is why he’s so focused on merit. Why he doesn’t care about the environment. Why he doesn’t care about putting people out of work. Why he doesn’t care about transparently selling out to the alt right.
It’s why he has 13 kids and supports eugenics. It’s all about getting humanity to burn as hot as we can until this goal is achieved. At which point everyone will be forced to acknowledge Musk’s brilliance for saving us all.
It’s all ego driven, yes, but in furtherance of this lofty goal of saving everyone from themselves.
EVs are small potatoes to him at this point.
