AlphaGo is not conscious.
DeepBlue was not conscious.
If we wait some time (the mythical 20 years) we will probably build a machine that is so complex that can simulate consciousness so good that it will be undistinguishable from human consciousness.
By the way, how are you sure that humans are truly consciousness and it's not only a simulation of consciousness made by the neurons?
