If ETCs persist over long reaches of time then we need to explore their likely evolution. As the famous physicist Niels Bohr once remarked, it’s hard to make predictions, especially about the future. It’s probably impossible to predict how a billion years of biological evolution will pan out. However, one might argue that biological evolution becomes increasingly irrelevant once a civilization reaches a certain level of technical sophistication: cultural evolution vastly outpaces biological evolution.
Wow. Cultural evolution outpaces biological evolution when civilization reaches a certain technological sophistication.
