I was thinkin' about science fiction and technological explosions. A scifi writer and utopian once said something about how "machines will eventually take over so much of what we currently do with manual labor, humanity will be in a state of enforced leisure. What an envied thing it will be to work!" (That's not even close to an exact quote.)
Humans are, of course, really inefficient at a lot of things.
How does one measure efficiency of creativity?
