Yeah, while there are some folks that are die-hard must have gas cars, lots of other folks experience instant torque, smoothest and quietest drive imaginable, and replenishing range without having to go out of your way to a station. Wondering when the next maintenance needs to come and there's no oil, no wearing belts, no super hot engine bay, just some things like wiper blades and a bit more rough on tires owing to generally higher weight.
There are downsides and awkward fits for some people. My apartment dwelling colleague would be screwed since his place has no available residential charging. Road trips can be more inconvient (though viable and perhaps worth it if you are taking a road trip every few months but spare yourself a weekly trip to the gas station). But certainly there's a market for which EVs provide more value than combustion vehicles.
Also, Elon rolled most of that 'future AI empire' stuff into SPCX instead. Meaning that even if investors wanted to believe it that, they know that Elon can play shell games and put the prize wherever he wants and the investors are not able to control that.
