I think the time to have that discussion is when the volume of neural tissue we're talking about is similar to a mouse's brain, until then it seems too detached from the realities on the ground to be much use.
I think that's too late, because by then we might make great leaps and show this technology is feasible, and you know as well as I that it's hard to put the genie back into the bottle at that point. Well all just ignore it and pretend we know there's no one inside.
