Well this is the other side of the public opinion on Elon Musk. His companies have done a bunch of things, ranging from impressive to bad. As outsiders all we know is that his involvement with, say, a rocket that can land itself is somewhere between "Elon single-handedly designed, constructed and assembled every part of it" and "Elon told someone the rockets re-usable". There's no way to know, but you and a legion of people seem to be portraying his involvement as closer to the former (literally "He’s also built rockets that land themselves..." - come on)

Honestly this discourse has played out a thousand times over. Some people love him, attribute all his companies' wins to him and memory-hole any of the fuck-ups or gaffes. Some people acknowledge his business acumen, don't quite believe the hype on the company-level achievements that get attributed to him personally and find his personality as portrayed on traditional and social media to be grating.

I'm clearly in the latter group and I think that's a pretty uncontroversial position to take.
