Re: Point Whoosh.

I said "build it with your bare hands". Beyond "magic" materials, we cannot build a space elevator. Just as without the thousands of people helping, and the specialist factories and machinery, you cannot build an iphone.

Rockets, phones, computers etc are increasing the fidelity of existing skills and technology. They are reaching under the limits of physics.

A space elevator asks to reach the limit of physics.

I never said "impossible". I said "impractical" (and as an example, we are starting to hit the impracticality of nano scale etching processes on silicon chips, so limits exist).
