Predator bots cooperate, they just limit their cooperation to other predator bots in consuming the Chump bots.
It's a recurring theme for me lately. To cooperate with those who would cooperate with you is good; to cooperate with those consuming you is not. Cooperating with Predator bots only makes it easier for them to consume you. Pacifist bot = Dinner bot.
Here is an interesting blog post about a guy who did a resume experiment between two positions which he argues are by experience identical, but occupy different "social status" positions in tech: A software engineer and a data manager.
The author concludes that positions that are labeled as code-monkey-like are low status, while positions that are labeled as managerial are high status. Even if they are "essentially" doing the same sort of work.
Not sure about this methodology, but it's food for thought.
