Selfishness re-considered

Physicists suggest selfishness can pay 

Frank Tipler thinks that games theory explains why selfishness doesn't pay, and that therefore the future  Omega Point that is God naturally doesn't like it.

I didn't realise that so much thought continues to go into games theory, but this article notes how there has been recent controversy over whether previous conclusions about how to best play the prisoner's dilemma  still hold up. 

This is hard to summarise, but it's interesting to note that Freeman Dyson is one of the guys putting thought into this.  I think the conclusion is that it still seems safe to assume, in an evolutionary context, that co-operation is best.

Lucky for Frank, then...
