Most ideas that get “selected” by culture are demonstrably improvements in terms of local objectives: the cases where we have chosen an inferior technology or scientific principle over a more productive or accurate one are the exceptions that prove the rule. And even when we do briefly choose the inferior VHS over Betamax, before long we have DVDs that outperform either option. So when you look at the arc of history from that perspective, it does trend toward better tools, better energy sources, better ways to transmit information.
