Ultimately the galaxy, indeed the sum of the universe in its entirety, was mostly nothing; average it all out and it made a pretty good vacuum. But w… - Iain Banks

Look at these humans! How could such glacial slowness even be called life? An age could pass, virtual empires rise and fall in the time they took to open their mouths to utter some new inanity!
