Your Darwinism favours the 'inside crowd' who are not necessarily very smart but have the connections necessary to give them the info not to inject. And it doesn't factor in the huge efforts on the propaganda side which is malicious. It would be better to have a future world where people have survived by supporting each other. Otherwise you're going to have neo-liberalism on steroids on the other side of this. And therefore the same problem again, probably quicker this time than 80 years or so.
