I never meant to imply that AI didn't have these options, merely that it takes far more work than people realize to make it sound real.

You can give the command for a block of text to be 'sad with a bit of anger,' but it will apply that to the whole thing. What if you want the 3rd line to be wistful, and the 5th line to be confused, and so on?

That's a lot of massaging.
