Wally , what I think you're missing is simple. How one communicates among a group of peers about a particular subject is generally very different than how one might talk about the same topic during a lesson or clinic. When instructors start talking to each other, yes, sometimes things go tech. That's what often happens. Case in point, my kid and I were watching a really cool program about quantum biology last night. It introduced concepts and thought in laypersons' terms. We dug it, but I'm sure we'd have been scratching our heads if we attended their professional conference.
When skiing with
@Zentune this past season, on the hill I don't think either of us went into the weeds much on ski talk, but did discuss how too much talk 'from above' on the hill just isn't much fun. We pretty much just skied and had a rippin good time even though we both enjoy geeking out on tech talk.
Good conversations, instruction, etc... are evidenced by smile and commensurate mental/ physical engagement. Droning on, rhetorical questioning, and 'my way or else' linguistic gymnastics are generally met with yawns, eyes on the snow, and much weight supported on ski poles. Good is good, and bad is bad. There's always wheat and chafe in the world.
