> Only a very tiny proportion of problems fit into that category I think more correctly, only a tiny proportion of solutions to problems fit into that category, and I think that's largely because of the street light effect. The entire history of math and science has been written by people working out problems in their head, or on paper, which is more or less a serial process. People just don't think well in parallel, and until recently, neither did computers. We have a lot of serial solutions because that's where the light was, basically. I think we're going to start finding a large variety of problems that turn out to have parallel solutions -- including a lot of problems that we didn't even know had solutions.
