Has AI delivered?

Here's a good article that talks about the lofty promises of AI, which go back as far as the 50s, and have yet to materialize. The article also gives some examples of recent AI successes. One of summary points is that the classical definition of AI isn't where most of the progress is being made. Rather, it is in specialized system.

A rather astonishing figure is that Microsoft Research employs nearly 1,000 PhDs that are actively working in the field of AI. Wow. That's about a factor of 10 larger than I would have guessed.
