I don't think you quite realize the implications of what you're saying.

Surely you don't actually believe, or even desire, for everyone to fully understand everything that they say... No room for questions, uncertainty, bewilderment, etc?

If someone is feigning competence via AI, that's the problem. Not Ai.

If they use Ai to polish a communication, be it statement, question, etc, and they do it in a thoughtful manner to ensure the final communication clearly and effectively communicates what it should be, there's no problem with that.
