Whether big or small. We all have that one thing from Scifi we wished were real. I’d love to see a cool underground city with like a SkyDome or a space hotel for instance.

As AAA said in a comment beside me it isn’t so much that I expect it would predate a space elevator. Simply that it is possible with current tech rather than still waiting on additional moderately likely breakthroughs like long chain carbon nanotube tether.
Also there are plenty of options to have the vast majority of the material be from space and not the surface since the core idea is a metal like copper being spun above orbital speed after being made into a full loop then used for the mag lev to keep at ground speed. There are absolutely a lot of astroids that might allow for that.
