I think it's more interesting to ask whether computer emotions are possible. (Not merely the emulation of emotions.) A simple definition of consciousness is the difference between being asleep (mostly oblivious to self) and awake (aware of self, environment, and relationship). Even then, a machine can negotiate terrain. But add emotions and you get potential for creativity (non-programmed, original output) which is a testable measure of sentience. Consciousness can be faked. Original work can't - certainly not original work that 'touches people's souls'. Somewhere in there is a machine that earns my ungrudging respect. It's not a formula: it's a feeling.
