My statement assumes parity, describing an ideal scenario. I believe that's what the parent described from his experience, today.
Assuming subterfuge then my statement wouldn't apply, obviously, as the flow of information wouldn't exactly be symmetric. Symmetric information flow implies a commitment to operate in good faith with free exchange.

The trick will be to maintain parity. This may be a fool's errand, but that point is key. It may be that only 0.01% of intellects eventually maintain symmetric conversation with AI, but that is important, nonetheless.
