While the tech is impressive in itself, still doesn't look to be something I'd pay for. The lip sync is annoyingly off, and the bland expressions that comes from not understanding context make the communication even worse. If having a visual talking head is that important for a project, still seems better to just hire someone.
(On a side note, I'm not sure I understand the appeal of emotionally bland fake-smile talking heads in general, even when they're real.)
Mass influencing with added custom targetting. Or fake id-ing someone else. Honestly I can’t think of anything other than that. It’s just information pollution for the most part probably. Now if they would have worked on a digital sign language avatar, that would be something innovative or useful.
Just wait until big companies start doing it. Then everybody else must do it too. Just look at how people copied the boring corporate web style which is now all over the place.
