Robotics and developing countries job loss

 There is a lot of work being done on this right now. Undoubtedly our economic future will be changed by robotics and AI. Jobs will be lost and created.  My question is this:  The google AI that recently won the Go tournament, while an apparent genius at the ancient game, did it know it was playing a game called Go?  

Sentience is what it does not have. A chainsaw is much better at cutting things than a human –but does the chainsaw know it is cutting anything? It is my contention that until AI are sentient they will create more jobs than they destroy.
