He didn't create Tesla or SpaceX. About the only company he created from scratch was the OG “X”, which then became PayPal. Credit (lol) where credit's due, that was an ingenious idea, but Musk is clearly this one-trick pony that has been living on borrowed time and fooling everyone around him into thinking he was some sort of genius, by buying up fledgling companies and manage to hire decent VPs and executives and not run them straight into the ground.
He thought he could do the same with Twitter much later in the game and do it alone, because… I don't know, manbaby temper tantrum, anyone? In any case, hubris got the best of him and the mask has fallen. In the meantime, we all had plenty of opportunities to learn about Gwynne Shotwell's and NASA's subsidies' crucial role in SpaceX's continued “success”, and see just how crappy his cars actually are when compared with properly made EVs from mainstream automakers (again, credit where credit's due: I distinctly recall Musk saying something a few years ago to the effect of having invested in Tesla just to get other automakers to take EVs seriously and transition the entire industry onto them, and that it being a successful company was just a bonus… Oddly prescient, much like his comments regarding a potential Twitter bankruptcy post-acquisition) and how many empty or otherwise failed or delayed promises he could spew.
Here we are, poor imposter syndrome-stricken ADHDers, highly competent but constantly doubting ourselves and our abilities, while this buffoon burns billions of dollars (with a B) while being called a “genius”. This circus ends now, I'm afraid; we're not taking that bs lightly or silently anymore.
