SpaceX blew up an entire launchpad because Musk thought flame diverters are gay, or something.
And, yes, Twitter is now a shithole.
Musk has a singular goal as far as I can tell: to make humanity a multi-planetary species. All of those things are testing the boundaries of what's possible in areas that will or could be very important for building a permanent settlement on Mars.
I posit that while there's much room for debate around whether or not those projects are viable, as far as I can tell everything Musk has done has been in service of building the corporate framework, talent pool, skills, and technology necessary to colonize Mars.
While my own views are likely closer to Musk's than I suspect yours are, I share those concerns. I don't think I'd be interested in moving there, at least not in the initial waves.
My optimistic view of the future looks more like "The Moon is a Harsh Mistress" than "Total Recall".
Hyperloop and the Vegas Loop are projects used to justify the existence of the Boring Company. The Boring Company's tech is definitely relevant to extraterrestrial habitat creation.
Just to add that to the crazy pile.
