Is AI a growing field?
frisco: If by AI you mean machine learning, yes.  If you mean "human-like-interactive-thing," yes but not in a way that means we're substantially closer than we were 15 years ago.AI in the ML sense is quickly becoming critical to business and is opening up lots of possibilities that we could only dream of 5 years ago.  At its heart, Google is basically an ML company for one big example.  Facebook is moving in that direction as well.  There are lots of startups solving old problems with AI, too, such as Knewton (tutoring), and for some self-promotion, my company (Quantios).
