But humans didn't evolve to be the fittest organism through strength or individualism. We're in our position through social cohesion and cooperation.
The most successful people I've seen got there through cooperation, coalition building, and community development. Some jerks also succeed, and are used as examples of why being a jerk is necessary or easier, but it's fallacious to think every local jerk is following the footsteps of bezos or musk.
So the next time you find yourself thinking, "the best engineers are jerks, because it's a social Darwinian landscape", remember that the strategy that seems to be winning today is "strength through social cohesion".
