It is factually true that Elon Musk has a reputation for saying things will happen that do not end up happening. Picking out some things that you like about him and posting them while excluding the dozens of publicly documented examples of him either lying or (very charitably) being so “hopeful” that he’s disconnected from reality is indistinguishable from volunteering support.
If your Tesla (made by a company he took private at $420/share) makes you passive income as a robotaxi while you sleep, which you spend paying off the loan you took out in 2020 for the ticket to Mars that you bought to avoid covid which ended up being pointless because nobody got it past April then I’d understand being confused about his reputation. If not, you kind of just posted a roundabout way of saying that you don’t care or notice when he makes stuff up.
