Just like the "tesla hyperloop" or whatever they're calling it, it's not about innovation. It's about keeping his brands in the public eye as a form of marketing. Even if on a logical level we all know it's horseshit, it still keeps himself and Tesla salient.
He can afford to burn an incomprehensible amount of money on stunts for outcomes most people would consider inconsequential.
I'm not saying it's 4D chess, it definitely isn't. He's not particularly intelligent in that way. That said, I do think there are some very simple reasons for him to do this that go beyond his absolutely insane delusional ego.
He has enough money that he can continue funding whatever he wants regardless of public opinion. He literally exists at a level where any press is good press as it keeps him fresh in peoples' minds.
These concepts are not mutually exclusive. You can be right about AI considerably overstepping boundaries and still be exhibiting classic signs of paranoia issues, which OP is.
Their immediate response to people not reacting to this post and their comments is to immediately jump to the idea that they're being targeted by their designated enemy. That's not particularly healthy.
I'm worried that AI is becoming the new gangstalking for tech aligned people predisposed to disprdered thinking.
