I don't launch rockets into space, don't want a housekeeping robot, don't have a Twitter account, don't do ketamine, and have never been laid off from a government job, so I can't speak to any of those things which Elon has involved himself with more recently.

My personal experience with Elon's promises is through the Model 3 which I do own, and essentially none of his promises for it have materialized. It hasn't morphed into a revenue-generating taxi which drives around strangers at night; it can't be summoned from across town (or even across a parking lot); it can't even safely drive itself without oversight, which was a goal only "months away" in 2019.

You mean the tele-operated "autonomous Robots" ? Also, I'm waiting for >10 years now for his (really!) self-driving cars he promised would be just about 2 years away - every 2 years.

SpaceX is what gives him leverage but the success of the reusable rockets are the engineers behind it - he's just the ketamine-driven hype-man that drives the stock via publicity now.
