Space is basically half the cost of it's competitors on a per kg basis. And while previous experiments like the DC-X existed, SpaceX absolutely gets credit for the first operational reusable rocket stage.

And I say that as someone that despises Elon and the way he casts his companies as due to his personal technical genius.

Not true. What about STS?

Eh that's a spaceplane and solid rocket booster shells which I see as categorically different, and an absurd failure on a cost per kg basis.

It was a spaceplane and also a rocket. It literally had fixed rocket engines and was carried up by separating rocket stages. And yeah, it was expensive to operate, but it was built in the '80s and it truly was the first reusable rocket regularly flown, rather than being merely an experimental craft.
