I just started reading the book "2312." It starts on Mercury, where we built a city that constantly travels along rails to avoid the cataclysmic fire of the sun.

Once upon a time, we thought big. We built bridges. We carved new rivers. We sent men to the moon. But we've stopped thinking big. Did you know Saudi Arabia's building a tower that's almost twice as tall as our tallest building? Saudi Arabia ain't part of "we"? It ... That's not what I ... Oh, shut up.
