Whats important is that people are made aware of all the arguments, presented with all the evidence so there is little recourse for the masses to say they were oblivious and deluded (the sheeple as I call them now)....so they fully own what ends up happening long term. But then who really thinks about descendents way in the future (like say 5 - 10 generations from now)....where the real multiplier effect of what we do today will probably have maximum effect on the ground? We are overall quite fickle, transient and impulsive beings. I honestly have lost a lot of hope in humanity since peaking somewhere in my teens....but now my solace is in the end, w.r.t the universe, it (humanity's fate) probably matters as much as knowing the exact number of asteroids orbiting the sun.
