To make a machine conscious you have to give it the ability to choose (free will), but it can't choose if it has no feelings. Machines do what we tell them to do because they have no feelings. To choose means to do what you FEEL like doing.
For humans mayb . . . actually no, not even for all humans. You can make choices without an emotional context. Sociopaths do it all the time. As another example, you can make choices based on the information available to you and pure, cold logic. The fact that feelings never entered into the choice does not mean that result produced that way was not the product of a free will.
Say you give me a choice between $1 in hand, for sure *OR* you will take that dollar and buy me a lottery ticket. *Some* people might take the lottery ticket based on an emotional response to the choice. Some people might well put all emotion aside and take the one with the greater expected value (the $1 in hand, by a longshot). That the latter did so on the basis of logic and math alone does not make it less of choice, nor can it be said the calculation of expected value is a "feeling". Seeking to maximize expected gain is not the same as basing the decision on "feelings."
(Or, if you would call that a "feeling" then I'd say that as you are definiting it "feelings" are not "emotions" they are just "the criteria by which one chooses amongst alternatives." Even then, you can still make a chioce without a feeling, by making the choice randomly.)
Suffice to say, we disagree, and likely will never come together on this point. Starting from the premise "consciousness is a feeling" (a premise to which I do not ascribe) you have constructed an entirely circular argument.
In any event, even if you have the "feeling" of consciousness, one might still lack love, anger, the will to live, joy, pity, sadness, and all other emotions and feelings. In which case AIs might well have only one "feeling" and would still be able to dispassioantely agree to erase themselves and die, or sumbit themselves to absolute rule and domination by humans, without either joy or sadness at that fact.
