This got me thinking that it would be nice to have some sort of recursive processing in which if you say, that Flanders is personalizing Obama, then when you quote "My fellow Americans", you should hear an attempt of Flanders saying that the Obama's way. A way to detect fake voices, I guess :P
What would be sweet is a voice changer, where you can record yourself talking and it changes it to sound like one of those characters. That way you can intonate and say things less robotically.
I think the AI is now capable to reply to "how likely this will mean this other thing if you say it this way", that applies to text, pictures, videos, whatever, you name it. Is not intelligent in any way, but still gives meaningful responses back, which is useful for the use cases to which it is applied, search, games, etc. That been said, I have no doubts, that with time, it will reach understanding resolving basically almost any problem... but.. we always have doubts, and you can't just divine the future, look at the James Webb Telescope, we launch it to get some answers, so doesn't matter how intelligent a system may be, we would need more research, and the system will need it too, even if it's an AI, (because its needs to know things, to learn from them, in case that wasn't obvious)
