I think you would have to justify why humans share a kind of consciousness that is tangibly different from AI while maintaining that we have no apparent means of discriminating between the two. It would seem that it's a difference without meaning.

while maintaining that we have no apparent means of discriminating between the two.

Yeah, and that's part of what makes this whole conversation so frustrating. And maybe also pointless in the end. We have a hard time even establishing for certain that we ourselves are conscious. Even more so that "each other" are conscious. Now extend it to some "artificial thing" running on an entirely different substrate and... all bets are off.

My argument though, is not that "AI's are conscious" or even that "AI's will definitely become conscious". I just have an issue with fervent assertions that say "No, AI's cannot become conscious" while not really providing any particular justification for that position. I think a more neutral "wait and see" position is more honest.
