Other than the obvious malicious uses of this technology, it could be great for multimedia, great for creative control for cast, great for virtual meetings to always look “your best” (as determined by each individual, e.g. clean-cut pristine, and/or preferred gender, and/or favorite anime, etc.). There are also use cases to hear letters spoken by a lost loved one, or replace the Three Stooges with politicians. Tons of “safe” use cases that I am looking forward to.
