When I was going to school, the thing that kept me out of jail was books. I could go read what Aristotle wrote. I didn't need an intermediary. A book got right from the source to the destination. But the problem was you can't ask Aristotle a question.

As we look towards the next 50 to 100 years if we can come up with machines that capture an underlying spirit, an underlying set of principles, an underlying way of looking at the world then when the next Aristotle comes around, maybe if he carries one of these machines his whole life and types in all this stuff, then maybe someday after that person's dead and gone, we can ask this machine: 'What would Aristotle have said about this?' Maybe we won't get the right answer. But maybe we will. And that's really exciting to me.
