I interpreted GP's message as "We used to lean-on and learn-from our friends, families, and coworkers, and insodoing we ourselves improved in a symbiotic way".
The "job" in the speech example would be "hey Joe, can I run this speech by you?"
In that scenario, the friend would:
* feel valued,
* connect with you,
* have something to do socially instead of "sooo uh whatcha been up to... uh... nice weather...", and
* get to hone their own speech skills by critiquing in a safe environment.
And.. yeah... it is the "job" of a friend/coworker to say "yes" to that question, right?
Ok; That's good feedback. Job may not have been the right word. I admit I didn't pass my comment through an LLM, so thank you for helping me improve and push harder. ;)
