Computers are capable of a limited form of consciousness, and as such we could use them to create a kind of simple artificial life form. Computers are able to receive sensory information, and can be programmed in such a way as to effect a kind of growth over time (programmed to check for certain factors and improve efficiency as a result), and could be connected to a self-moderated industrial complex capable of producing copies of the machines being used (limited reproduction).
But what computers are NOT capable of being right now is sentient. They are not able to be aware of their own awareness. They are not capable of goal-oriented self-direction (they cannot decide what goals are preferable).
I suppose it is barely possible that if we created a simple artificial life form and allowed it a billion years of industrial evolution, then it might evolve a sentient construct, but something tells me that that particular experiment is beyond the time frame of relevance for human endeavor.
