A world where we don't need people at all. Kubrick's machines are more real than people, but boil that away and all you have is a lonely man, talking to walls in the dark. Once the machines start talking, I imagine a lot of people will turn away from men completely. People can be cruel. People can be thoughtless.
People can be emotional at all the wrong times.
Machines would be so much better. Supportive and loving in a perfect digital way. Loving you because they're programmed to love you. Not so with people. People have this icky quality of randomness that comes out at inconvenient times.
