Do computers have consciousness?

[Zen Badger]

And we should also keep in mind that even if we do create a conscious machine, we don't necessarily know how it will behave, especially if we don't create it in a way that it interprets sensory information and acts the way we do.

I think, odds are, if it is patterned after human consciousness, it will be developed the same way, through years of learning and training, and vetted the same way, by an accumulating record of good performance. We can't predict how any single consciousness will behave now. How would it being non-human change that?

That's assuming it is the result of a controlled experiment.
If it should spontaneously arise free of human manipulation, then we might not even recognise it as such.

Fuck, it might have already happened. We wouldn't know.
