I remember someone a while back tried to pass off a script as being A.I. generated when it clearly wasn't and I thought to myself, will we need to develop a reverse Turing test? Of course some one already thought of that;
I assume you agree with the worry about the first part (fake pretending to be real). For the second part, I left out the word, and was more thinking about 'wondering', but I agree the sentence structure suggests 'worry'.
I agree it is not a worry, at least not of the same kind. I do worry a bit though about assuming something and reasoning/discussing with that premise, which is nullified if the premise was wrong.
