On its basis it is hard to think we won't this at some point as it promises essentially orbit-like capability on the surface, so everyone has the right to dream we'd get this sooner.
..well known example is given..
"Has Elon actually promised something concrete about this?"
you can see that those things are different.
Hyperloop was always being to be extremely expensive and Elon's role on it was never but just try to be a catalyst for more innovation towards it. He used terms like "open-source idea" and did that student competition to try to kind of drive other people to grab the idea. Things like FSD are instead considered concrete and produced by his companies.
Your kind of thinking would say that no one will ever need more than 840k of memory or that rifling will never take off
