1. Starlink, which you provided

2. Made the modern EV relatively commonplace; no other manufacturer was taking it seriously until Tesla succeeded, and took many years to catch up, although they have

3. Re-usable rockets / higher launch cadence leading to significantly cheaper costs to put things in space. No major competition yet.

Falcon rockets, starlink, Tesla. They all pushed the envelope in their field. Are the stocks overpriced? Yes. Did they do impressive technical work? Also yes. They might get surpassed by competitors, but that is to be expected for all companies. But they clearly did something special there. And I deff am no Musk fanboy, but you have to give him the credit for establishing those systems.

Tesla may not have pioneered fundamental technology, but it put together a combination of price and utility that nobody matched at the time. Find me anything in 2018 like a Model 3 that wasn't a compliance car.

Profitably reusable rockets were a major accomplishment. People like to argue against this. Every argument I've seen is either saying it doesn't actually save money or it wasn't new, neither of which is correct. It's very hard to argue with the numbers here; SpaceX is now launching more into orbit than every other launch provider combined.

I think the main reason people downplay these things is precisely because his own claims are so exaggerated. Doing 165 orbital launches in a year just doesn't sound impressive when he promised we'd be sending people to Mars years ago.
