One of the possible characteristics that can distinguish a conscious AI of any other being, is immortality. Nevertheless to be immortal an AI should have the ability to transfer his conscience to another body, but is that really immortality or just recreation?
Imagine the following scenario: A conscious AI have all its data storage in one HD, HD1, and that HD is very old, so the AI need to have its data transfer to another HD, HD2.
When this transfer is perform, the HD2 receive a copy of the data of HD1, not the actual information, soo, we can say that when we erase the data of HD1, the AI died, and we have a copy of that being in HD2. If you think about that scenario, you will realize, that we are facing the same problems that we would have, if we have invented a machine, capable of "transfer" a human consciense to another body.
To sum up, in the same way we cannot be really immortal, because the everything is perishable, a machine cannot be immortal either.
