Humans are a learning algorithm in a body. Very, very few learning algorithms incorporate original thought, because it's computationally expensive. Extremely, extremely expensive. Genetic algorithms are close to the only ones and the best reason to use generic algorithms is when you have no example data whatsoever, and even with datacenters full of machines, a lot of patience is required. Otherwise, genetic algorithms are going to get clobbered in performance by almost every other algorithm.

Which brings me to my point : imho the chances that humans are capable of real original thought is nil. Don't get me wrong, humans are very capable of creatively combining ideas from very different disciplines and non-human sources to arrive at surprising insights and works. But I'm pretty sure humans are not in fact capable of creating something out of nothing, even when it comes to intellectual works.
