I liked Elon until about 2018. Since then he's gradually degraded from "interesting founder" to "guy who picks fights about weird topics on the internet" to "absurdist oligarch actively working to destroy institutions which support average Americans."
I certainly suspect that there were always elements of what he's become that just weren't as publicly apparent.
I stopped liking Musk when his first wife's tell-all "I Was a Starter Wife" came out in Marie Claire in 2010. Yes, penned by a disgruntled former spouse, it felt nonetheless authentic and immediately believable, and all the events since have generally confirmed her characterization of him.
As so often, it's how they treat the women around them that tells you a lot about men.
What did you like about him until 2018? He is not some visionary or genius or even smart. Neither is/was he a decent person to deal with (read up on his PayPal days). He is however, extraordinarily ruthless and thin skinned.
So what is it that you saw in him that you liked him?
This. He is definitely not a genius and not even smart. He can’t formulate any interesting, original thoughts. He parrots, daily, dumb ideas and state propaganda (for example, russia) without any critical thinking.
The average person on the street is smarter than him.
My Tesla drives itself virtually everywhere. All I have to do is look out the window, which I'd do anyway. The only times I control my Tesla are when pulling in and out of my garage and when I need to get it going so FSD can take over (and occasionally when parking).
I certainly suspect that there were always elements of what he's become that just weren't as publicly apparent.
