The next 50 years: A personal view

I review history, starting with Turing’s seminal paper, reaching back ultimately to when our species started to outperform other primates, searching for the questions that will help us develop a computational account of human intelligence. I answer that the right questions are: What’s different between us and the other primates and what’s the same. I answer the what’s different question by saying that we became symbolic in a way that enabled story understanding, directed perception, and easy communication, and other species did not. I argue against Turing’s reasoning-centered suggestions, offering that reasoning is just a special case of story understanding. I answer the what’s the same question by noting that our brains are largely engineered in the same exotic way, with information flowing in all directions at once. By way of example, I illustrate how these answers can influence a research program, describing the Genesis system, a system that works with short summaries of stories, provided in English, together with low-level common-sense rules and higher-level concept patterns, likewise expressed in English. Genesis answers questions, notes abstract concepts such as revenge, tells stories in a listener-aware way, and fills in story gaps using precedents. I conclude by suggesting, optimistically, that a genuine computational theory of human intelligence will emerge in the next 50 years if we stick to the right, biologically inspired questions, and work toward biologically informed models.This material is based on work supported by the U.S. Office of Naval Research, Grant No. N00014-09-1-0597.
