I wonder what would happen if the tech industry giants pooled their resources to build a metropolis elsewhere, wherever they could found a county and just go to town without restrictions on building height or whatever.

And then they could uproot their workforces (and if you took the combined employees of Yahoo, MS, Google, Apple, AOL, Facebook, etc, you would have moved the employee base) and move there, it would probably be the most futuristic city on the planet.

I mean, they wouldn't - or they already would have - because it isn't economically feasible. But that always comes off as a buzz kill since we just end up trying to grow new businesses like cancer into the ancient ruins of lost revolutions we call "historical preservation".
