While yes that is the ideal policy, it doesn't seem likely that it will be implemented by schools and they will probably continue to have them write essays, even if AI is a thing. Private schools would probably be lobbying the government to regulate AI and prevent it from writing essays and all of that or something rather than just do what you said.

The thing is, the arguments you just listed completely ignore the political side of things, as AI technology can potentially sway opinions and may just destroy the reputation of a politician even if he didn't do/say the thing the deep fake says he do (or will do). They will become so accurate that you wouldn't be able to tell if it was faked or real. Elections could be decided just by these deep fakes (in the near future). Like, people immediately reacted to a fake Trump arrest image on Twitter, just imagine that in the future.

If there was no political side to this, I would agree, this is not really a new problem. But the fact that there is one just concerns me. This isn't just about the silly little artist mad that an AI can do something better than him. No, this can be used and would inevitably be used by politicians to attack other and divide the populace even further.
