I think we can and will one day create unconscious robots that *act* like they have consciousness. We already have some unconscious robots that act conscious for certain tasks. Do you really disagree with this?
In any case I want to take a moment to address your claim that "consciousness is a necessary by-product of intelligence".
I notice first that the claim needs some disambiguation. I don't believe evolution scientists use that vocabulary. Generally they classify traits as either adaptive or non-adaptive.
Adaptive traits increase the probability that the host's genes will propagate. Eyesight serves as a good example of an adaptive trait.
Non-adaptive traits do not increase the probability that the host's genes will propagate. The red color of human blood serves as a good example of a non-adaptive trait. Blood looks red because hemoglobin contains iron, and hemoglobin carries precious oxygen to the cells. The redness of blood appears only as a "byproduct" of something else that has adaptive value.
Now then should we consider consciousness an adaptive trait or a non-adaptive trait? I think it clearly qualifies as an adaptive trait, and I think you will agree. Conscious awareness enhances intelligence and gives the organism more flexibility in dealing with multiple stimuli simultaneously.
As evidence of this we need only look at nature: conscious organisms like humans exhibit more complex and intelligent behaviors than do unconscious organisms like plants and microbes.
