For the sake of this debate, lets presume that somehow, magically, the studios and actors come to an agreement on the use of AI that satisfies evertone. The actors and/or their estates are all paid, and their likeness can appear anywhere as agreed upon, whatever.
In theory, this could open up a lock of potential, good and bad. All the MCU characters could have their own TV shows (where that falls on good or bad is up to you). Actors who can no longer act can show up (like say, Bruce Willis). And more things I can't think of.
Personally, minus maybe some extenuating circumstances, I don't think I could. Uncanny valley in spirit is still uncanny valley.
You?
