Amazing. and BEAUTIFUL besides. However I believe we are still at least 20 years away still from having the technology to build such a hyper-tall structure. Nano-carbon would have to be the primary building material because it's much stronger and lighter than any materials currently available.
I think that in, say, 50-100 years from now, such hypertalls won't be uncommon.
But not yet, not now. Someday. Maybe.
Be patient.
