Yes this is a fascinating discussion topic and has been so since the dawn of computers. I personally think that autonomous AI is not an impending problem for humanity, it is no more than a scientific goal to prove it can be done. Computers already run things more efficiently than humans can and having them sentient will not help matters. Humans is an enjoyable programme and in this series we are seeing the beginnings of personality developing - this is another minefield of course. Must go, my laptop is demanding an update!
