To be honest, this AI is the closest thing to a sentient being I ever read about. I don't think it is sentient per se according to my own interpretation of being "sentient", for that it is not still capable of thinking out of the box, i.e. the context, personality, which are still set up or hinted by human.

However, I also believe that given enough effort, it's quite likely to see a "real" sentient AI being in forthcoming years.
