This is the problem with the dialogue around Musk. He's not 99% vaporware, he's 80-90% vaporware. That's problem enough.
In some cases, like Tesla, the vaporware is propping up the company (pivoting to robots!) even though sales are crashing because of the self-inflicted immolation of his personal brand. This is not going to end well.
Going to the moon was, at the very least, demonstrated as technologically possible in the 1960s, and you can literally go watch a Starship launch if you want. I have a very hard time putting it in the same "entirely prospective" category as androids, self-driving taxis, and Mars bases.
