We all remember September 11, and how it changed the world forever.
At the world's first conference on AI in 1956, Allan Newell explained how how Logic Theorist was capable of proving theorems from the Principia Mathematica; immediately after him, Noam Chomsky explained why behaviorist psychology was computationally incompatible with the basic tasks of grammatical language use.
Never forget!
It's really interesting to read about how much of the point of that MIT Symposium on Information Theory (9/11/56) was to say "fuck you" to behaviorist psych. Most of the presenters were organizing around this idea: that the effectiveness of programmatic rules in computing proved that it was meaningful and useful to discuss human intellection (at least) in minimal conceptual terms. The computer proved that "memory" wasn't just a hobgoblin of the Freudians.
