Others have said in this thread, and I'll repeat it: I do not understand why so much of what I see around Elon seems emotional. And I've seen the same from others about other public people, and find it just as irrational and, well, odd to me.
Elon is often portrayed as a genius, but no one seems to define why or in what capacity. I do not believe that, in the strict sense, he is. He is a gifted leader and at least intelligent and educated enough to recognize innovative thinking and technology. Steve Jobs was such a leader and visionary. He was also well known as an "@ssh0le" and a tyrant to work for. I walked past his Mercedes several times, only to see it parked in handicapped spots outside Apple's old headquarters.
Looking at significant innovations, you can point back to great science fiction as the source of thought fodder. The tables and phones we use today were well-sorted in the science fiction of decades past. The rockets landing, robots working, and electric cars whirring were also well-worn. It takes great engineers to build those into reality, but it takes outstanding leadership to believe in it, to believe it can be better, and to sell it to investors and the public.
Elon is a fair target for criticism. I don't like some of his trollish behaviors, but I don't eat dinner with him either.
Twitter/X:
He put his money where his mouth is on X and appears to have a chance of saving the company. If anyone really believed it was going to last before he bought it, they were smoking something. Time will tell if he can make it a go.
Politics:
He used his money in politics. All of the very wealthy people do, just more quietly, which is the key. It's their money, do we get to tell them what they can do with it?
DOGE:
He volunteered his time to step in and "help". You can debate whether what he did was good. I have seen people say that he caused harm, but I haven't seen anything substantiated on that front. I have seen the numbers substantiated on claimed savings, and no one on the other side of politics in the government seems to argue that those savings aren't real. But back to my point, he volunteered to go help. I haven't. What I've seen is a lot of hand-waving about potential harms, potential privacy issues, potential this or that. And, yes, disruption.
Otherwise, he leads some of the most innovative companies on the planet. Companies that are disrupting industries and will forever hold a positive place in history.
