Listener question: evolutionary disadvantage of the self concept?

Finding the concept of the self being pre-programmed into the system fascinating. I can see how the incredible ability to conceptualise is key within society and all the incredible things that have come from it. But I wonder if you could talk more about  if there is a point where the evolutionary benefit of having the avatar/self is outweighed by the suffering/threat to survival of having an avatar/self. Hope this makes sense?
