How many times do we need to re-define the same concept? Artificial Intelligence, Human Level Artificial Intelligence, Artificial General Intelligence, Strong Artificial Intelligence etc....
Lets pick one as a community and stick with it. I thought AGI was in the lead there recently what with the conference, journal and high amount of web searches but apparently that isn't enough.
Beyond that, I would like to see how they make their algorithm narrow for the narrow application of the Pac-Man game while keeping it generalizable. My guess is that they don't and this algo ends up being a "starting point" for narrow AI applications to rest on. In that case it's fine and interesting, but doesn't pass the test to integrating specificity within a general learning model.
