Given the amount of his personal wealth he put into Tesla and the financial tricks he pulled to get further funding (if what is said in Elon Musk by Ashley Vance is true), then it seems likely that Tesla would have gone bankrupt without him. Maybe any rich person could have done it, and electric cars would always eventually be on the trajectory they are now, but he was the rich person that actually did it. He should get some credit for that, I think. But it is right that he didn’t create Tesla, and he should definitely stop implying that he did, I agree with that.
On Lemmy there is disincentive to troll right? If you’re being too much of a troll you might get thrown out of your instance for making it look bad. Unless you selfhost of course. I’m not sure why botspam from selfhosted lemmy’s is not a bigger problem to be honest. You can deferate them but it’s easy to make new ones.
