I also think it's kind of pointless as anything other than a demonstration of the speech synthesis (which is getting pretty good). The Feynman character especially shows that while these models can pick up a bunch of the details about the surface style, they certainly can't be clever or insightful, which is the appeal of the people being imitated.

With respect to using the voices or faces of dead people, I do think it's interesting that the estates of the deceased can have some control over commercial uses of personal images. The estate of MLK I think still controls use of the whole audio from some of his famous speeches. But my understanding is we haven't yet settled whether synthetic / derived artifacts which rely heavily on existing photos or recordings should themselves be controlled in the same way.
