>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?

Nothing they said implies that.

What they said is they want the understanding of the person to be revealed in the communication. Not masked via 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.

Yes, if that ever happens in the real world, it would be ok.
