This is a hypothetical, not an assumption. I’m interested in your response to the hypothetical.
As a side note, experience isn’t a unidimensional value that is directly comparable. You can have more experience than someone else in one dimension, and the other person can have more experience than you in a different dimension. I’d never argue with my mother about how to perform a blood draw.
I already implicitly responded: this should be handled like in any other walk of life - a few probing questions, maybe a preceding dialogue, etc. Admittedly tech people probably don't know how to handle this outside of tech either <shrug>
You answered your own question:

When two such people communicate, it's rarely clear who knows more. Typically, I know more about the task I'm working on, and he knows more about X, and that's why I'm asking him about X. Sure, if he wants to know what I'm working on - happy to engage, provided he doesn't withhold the information I'm asking for.
Useful conversation relies on mutual purpose.
