Incredibly dumb approach.

You should ban using AI for the purpose of legal disputes, medicine, etc, profesionally.

Its not about the output, its about what you use it for.

I am also 100% okay with legally requiring a clearly visible disclaimer that AI shouldnt be used for x/y/z and its output should alwats be fact checked or whatever.

But trying to outright ban specific types of output is pointless and trivial to circumvent.
