Well, you've just given up the argument, and have basically agreed that strong AI is impossible
Not at all. Strong AI is not necessary to the argument. It is perfectly possible for an unconscious machine not considered "strong AI" to act upon Asimov's Laws. They're just rules for a program to act upon.
In addition, it is not necessary for Artificial General Intelligence to be conscious.
Mind is a phenomenon of healthy living brain and is seen no where else.
We have a lot to learn of consciousness yet. But what we have learned so far seems to indicate that consciousness is a story that the brain tells itself, and is not particularly related to how the brain actually works. Descartes self-referential attempt aside, it would be difficult for any of us to actually prove that we are conscious.
