Cool but probably not that interesting to the development of AI in Hollywood over the longer term. As the tech improves, at current rates, I expect we'll see something like VTubers on a mass scale. Companies creating their own virtual people - where they control the IP - and putting all their efforts behind promoting them instead of humans. It'll be cheaper and easier in the long run.

Same process as green screens or the rise of animation. There is a lot of pressure on the humans and once AIs crack acting they'll be much more consistently good than humans.
