Because it's nonsense. We're a decade past the promised rollout of full self driving, the hyperloop is a failure, the cybertruck is a flop, China makes EVs significantly better and cheaper than Tesla. The batteries they're selling are looking more and more likely to get leapfrogged by solid state batteries too. Half the world refuses to touch anything his companies produce.

Tesla stock should be in the shitter, but results don't matter anymore.

Hyperloop was Musk's tactic to distract from and destroy sensible public transportation. Tesla didn't work on it or plan for it.

Ya most of his shit is stupid though

It appears to me that your average human isn't particularly smart so this hasn't been to his detriment yet.
