Luis von Ahn on Human Computation

Although computers have advanced dramatically over the last 50 years, they still do not possess the basic conceptual intelligence that most humans take for granted. By leveraging human skills and abilities in a novel way we can solve large-scale computational problems and collect training data to teach computers many basic human talents. Professor Luis von Ahn — of the Computer Science Department at Carnegie Mellon University — discusses how human brains can act as processors in a distributed system, each performing a small part of a massive computation.
