It's also definitely the trend in human evolution, and kind of unstoppable when you think in big picture terms. There must be a literal race against it, with contingency plans and long-term Operations plotted in the ruling class, but ultimately they are fighting a losing battle I hope. It's really going to come down to man's capacity for courage.
"Ah, those endless forests, and their horror-haunted gloom! For what eternities have I wandered through them, a timid, hunted creature, starting at the least sound, frightened of my own shadow, keyed-up, ever alert and vigilant, ready on the instant to dash away in mad flight for my life. For I was the prey of all manner of fierce life that dwelt in the forest, and it was in ecstasies of fear that I fled before the hunting monsters."
Jack london, "Before Adam"
