Your EV knowledge is 3 years out of date. Both Ford and GM have well liked and selling EVs. Meanwhile Tesla's sales are cratering.
While I cannot remember the names of these sites, there were various attempts to create a shared platform website where you could create a profile and communicate with others. I remember joining a few at least back in 2002 before MySpace, Yahoo360. There was also Bebo which, I think, was for the younger kids of the day.
Lets not forget about friendsreunited.
Many Companies become successful being at the right place at the right time. Facebook is one of those companies.
Had facebook been created a year or so beforehand (or a year or two after) we would likely be using some other "social media" today. Be interesting how that would have compared to facebook. Would it be "more evil" ???
Regardless, whether its Facebook/MarkZuckerberg or [insert_social_media]/[owner]... we would still end up with a new celebrity millionnaire/billionnaire.. and would still be considered "a fool" one way or another.
That doesn't tell me anything about his ability to build "augmented reality" or otherwise use artificial intelligence in any way that people will want to pay for. We'll see.
Ford and GM have a century of experience building cars but they can't seem to figure out EVs despite trying for nearly two decades now.
Tesla hit the ball out of the park with EVs but can't figure out self-driving.
Being good at one thing does not mean you will be good at everything you try.
