The better question would be: Even if we did have such tools, what stories would be worth telling with them?

I don't doubt that we will eventually have something like this, in the same way we now have CGI with forensic fidelity. The problem will no longer be "How do we realize this?" but "What's worth realizing?" The new limit is no longer technology; it's our taste and our discernment, which are not being developed anywhere nearly as aggressively as our tech.
