Is Human Creativity a Form of Perspiration?

This is really what I was claiming way back in the AI episode. It's just a matter of how you happen to use the word knowledge. David Deutte said, okay, and then he started to give me the example of perspiration versus inspiration. He says,  the trial and error for AI, it just tries lots of different things, so it's just perspiration whereas with humans, you know, it's inspiration. And I'm not sure I can buy that argument. How do I know that human creativity doesn't use perspiration?
