Would you enter a building held up by tensegrity? I feel that to build the next generation of super massive structures in the 21st century we will have to use tensegrity concepts.

If it was properly engineered, sure, why not? It would be no different in principle from driving over a suspension bridge.

I assume all buildibgs I enter are properly engineered, but sometimes they're not. Two cases that come to mind:

Both were essentially caused by people making assumptions. You would think such things would be thought through, but sometimes they're not.
