I'd like to know from AI experts on HN. This is the third wave of AI hype in 50 years. Will this too lead to an AI winter like the last two times or are we really onto something ? Heres an interesting AI company I've found : http://www.celaton.com/solutions http://www.celaton.com/solutions It's already begun.

This time there are applications and revenue. In the financial sector, huge amounts of revenue. In the first two "AI revolutions", the startups all went bust. (I went through Stanford CS in 1985, just at the point that it was clear that expert systems were not going to be very useful. Much of the CS faculty back then was in denial about that. More recently, I took a machine learning course. It was taught by someone from Black Rock Capital, not an academic.)

  Interesting - can you describe the curriculum? Or highlight some of the differences of view that you perceived?

    The machine learning course, given at Hacker Dojo about three years ago, was right out of Andrew Ng's videos, pre-Coursera, with his awful blackboard handwriting. Support vector machines, that sort of thing. Not enough graphics showing what all those functions are doing. Most of that stuff has a clear graphical representation, but in Ng's original course, you're supposed to imagine it. A Stanford MSCS in the mid-1980s was heavy on mathematical logic. You could get through the whole curriculum without doing a floating point operation. I got discrete math, number theory (Knuth, vol. 2), proof of correctness, formal logic, proof of correctness, theory of programming languages, etc. Some graphics work, on a Xerox Alto. Dr. John's Mystery Hour, "Epistemological Problems in Artificial Intelligence", from John McCarthy. (He would describe a problem informally, then a miracle occurs, and it's in a predicate calculus notation where you just turn the crank to get the answer. It hadn't yet hit the logicians that getting the problem into the formalism is the hard part. Automatic symbolic math was in its infancy back then.)
