I think the key is to have the humility to realize that we haven't had another Euclid or Archimedes in modern times. Possibly Decartes or Tesla compare, but it's arguable. We've come so far and have such promise, and yet we have so much to lose. I would argue that far from being being doomed to repeating history because we forget, we have the possibility of being the first to wipe out our own race, either through inaction or brazenness.
