My model of Musk insists he can't actually believe it's a good technology (there are so many coins that deserve it more) and he's doing it to endear himself to bitcoin holders, sell like 30,000 cars (including upcoming luxury ones with thrusters on them, and flying ones (yes, battery energy density is reaching the point where they're going to start doing that)), and also massively boost his technical clout.
It bugs the hell out of me to see Ark Invest guy telling the "bitcoin isn't wasteful" story, he clearly sincerely believes it. I dunno. It's really hard to imagine musk being wiley enough to like that thread ironically, maybe my model of him is wrong and he started going senile like 6 years ago. But it seems just as likely I'm underestimating how often he lies.
