Sure, it's hard to predict if Tesla hadn't been formed whether electric cars would be as big as they are now (perhaps another innovator would've jumped in).

I'd agree that he's failed to deliver on the FSD so far, but I mean, it'll be such a shift (when either Tesla or some other group nail it which like I said I think is the most likely) that when we look back on it in 100 years we're not going to care how far their time estimates were out by.
