Prompt engineering is nothing more than learning and practicing how to communicate more effectively and objectively, in a clear and a lot of the times polite manner. I like to believe that it may be the starting point for humans to go back to investing properly into verbalizing and communicating with each other in a decent and fair way; and maybe that will be part of our salvation as a society.

This is really a good point that I hadn't considered. Ad hominem arguments don't work against an AI. I hope you're right about what this implies. It would be nice if AIs could teach us something about how to communicate with each other.
