Building the big boys was my gig before ret. They always started out of a WIDE and DEEP hole dug out of the good old mother earth and went on up from there. This thing is a joke. Never happen. The Archies dreaming this thing up were on drugs for sure with this ‘brainstorm’
I remember Wright’s “mile high” skyscraper had a 1/4 mile deep foundation.
Regarding this structure. I think, with the right technology, it would be quite feasible - in 70-100 years. But it needs to be suspended by a rock in geosynchronous orbit. And in seven decades, we’d probably have no problem micro-adjusting the location of the asteroid to compensate for different occupation levels, weights, etc.
If it ever failed, though, it would be epic.

... and you can be sure it was architects who dreamed it up, without ever bothering to consult an engineer or astrophysicist.
