Recently, NPR interviewed the man who “de-aged” Robert De Niro for the film, “The Irishman”. The conversation drifted into the metaphysics of computer-generated imaging:
GARCIA-NAVARRO: And what you’re describing is a technology that’s only going to get better and better, which I think brings up some ethical issues because as the technology gets more seamless and commonplace and those likenesses that you’ve just described get more subtle, could we end up doing away with the actual actor altogether? I mean, could it come to a point where a studio owns the digital image of an actor and just uses that instead of the real thing?
HELMAN: I don’t think so ’cause the performance has to come from somewhere, and that has to be the actor. And so just think about what it’ll take for a computer to do what Robert De Niro does. You need to train the computer – right? – to do those kinds of things. And basically, if you think about the behavior or likeness of somebody, how do you become yourself? You become yourself by living, you know, by having a bunch of experiences. And then you also have all the connections that are made in your face, the way you smile, all the cultural things that you live.
So if you want a computer to act like Robert De Niro, you need to train the computer like Robert De Niro. And then you spend a lifetime, you know, basically training the computer. And for that, you might as well just use Robert De Niro, you know?
Quite right, and more generally correct than I suspect Mr. Helman intended. Explanations pertain to the past, where things could not have been otherwise. The future will always be the realm of probability, else, to echo Mr. Helman, it will already have been.
The supervenient identity specifies its base. Otherwise, there is no explanation of the identity by the base. The point is: there are no loose ends – no theoretical De Niro’s.
