Actually this is wrong. Altruism isn't an evolutionary stable strategy thus it can't be absolute. Let's say we have a population of altruists then we get one selfish renegade. He will reap enormous short term advantage over the altruistic individuals. In the example above with the prisoner's dilemma he would never go to prison while the altruist would always serve 6 months when grouped together.
The selfish individuals themselves won't be evolutionary stable either. The evolutionary stable strategy will usually favour a polymorphism in the case of selfish/non selfish. This has been proven both by observation and simulation on several occasions.
Altruism will be the best strategy on average, but it allows selfish individuals to gain too much advantage and will break down with time. The idea is beautiful, but it suggests that evolution favours long term over short term. Evolution doesn't work that way. Evolution doesn't "think ahead".
Now ignoring the fact that they tried to use evolution as a part of this it's entirely possible that human society might move towards a state like this because we are able to think ahead unlike evolution. We can actually plan ahead and increase our long term success at the cost of short term. The cynic in me doesn't consider this plausible though.
