No we will never learn because we can't, our personalities and our design makes its so.
Cockpit gradients will always exist because you have someone who is more senior than the other
The FO knew what to do and why didn't he suggest it? Because he was too worried about being wrong and the captain thinking he was stupid, we have all done it at sometime in our careers and anyone who says that haven't is either lying or a cold soul...
On another note nice to see someone handle a stall recovery correctly and not just fly it into the ground
