> Having someone human there both gives them the answer much better than they can find themselves and gives them the knowledge that someone is there to help them, so they don't give up.

Yes. Even if the human doesn't actually give you the direct solution to your problem, but just reassures you that you are on the right path and with a bit more thinkingn you will overcome the current obstacle. (Or points out to you when you are blatantly wrong.)

Having confidence that there is a solution is often half the battle to finding one.
