Fuzzy Logic...?

" Fuzzy logic is a revolutionary approach to computer programming that mimics the way the human brain thinks and solves problems", or in other words... a computer programing made to "impersonate" a persons mind about how it thinks, and solves problems. Some advances to Fuzzy logic would be that it's cheaper. I think fuzzy logic is kind of confusing, and I'm not really sure what it is,exactly. I'm not really sure if it will "affect" my life at all, but for a lot of people around the world, it probably will.
