I believe the fundamental misconception here is that we believe that we have free will!? and machines do not. Do we? I think not, As Brian Greene says free will is an illusion. I read this not so long ago:
At any one moment in time our brain, however amazingly large and complex it is, represents a gigantic probabilistic computer that turns a set of inputs into outputs. The probabilistic part means that even if the same brain were to be presented with the same inputs it might produce a different observed output (given the complexity involved this is a complete hypothetical, as the “same” brain implies each of nearly 100 billion neurons in the same state). What is true though is that the probability distribution over outputs is entirely encoded in that brain. And hence there is no free will.
And we are largely "programmed" by our genetics. This is becoming clearer as we start understand the biogenetics behind the inner working of the brain. Our genetics are similar to the "program" fed to our computers.
I think our machines as they "evole" under our unwilling guidance will be more and more complex. We will eventually loose the capacity to distinguish it from human intelligence. Then the fun will begin.
