I suspect that acting itself will be reduced to algorithms. Expression of different emotions could be digitized. This could open further avenues of automation - authors could configure various different permutations (e.g. sincerity/sarcasm, surprise), the combination of expressions could be derived from context / sentiment analysis for the character, or perhaps each character could have a preset pack of opinions/values that informs their response. Given the constantly expanding capabilities of synthesis, these seem like natural areas that people will explore.

I agree that there is no need for any of this, but that's never stopped technological / artistic progress.

That seems to largely be taking the character out of characters. I think this maybe another case of "computer geeks think that {industry name} is easy and can be solved with computers".

Yes it feels a bit reductionist... "Love is merely a series of chemical reactions, therefore I should be able to compute text that elicits these reactions in a person and makes them fall in love with me."
