What he is is a man with a vision, who has made extraordinary wealth and is now spending vast amounts of that wealth on projects which further that vision.
Bezos wailing that he needs an enormous bung from congress is pitiful, I think we can all agree with that.
Electrification of transport, it's not a new idea - but Tesla has done more to make it mainstream than most others, by lighting a fire under existing manufacturers, showing what can be done.
Space travel - SpaceX nearly collapsed, but then they managed to get an F1 to orbit, and then developed the F9, and then started bloody landing the boosters and flying them again, and again, and again.
There is still a good chance that SLS/Orion will reach orbit before Starship, but if you count doing 85% of a lap as basically orbit then it will be a close run thing - if the first starship booster flight goes without a hitch then they'll get there first, if not then SLS has a chance in November - though SpaceX might turn up for a second launch by then...
Yes - much of their funding comes from NASA, but that's part of the commercial supply services which anyone can bid on and supply.
The boring company - Yeah, not sure I see the value in this vision particularly. But I don't expect everything he touches to be fairy dust.
