“Ladies and gentlemen, at this time we are told there is an accident on the train ahead of us. There has been a collision with a car. We are instructed to hold here and await further direction. At this time we do not know how long the delay will be.”
Whose fault exactly? Yours? Mine? No, it would have been the result of several billion human beings making relatively innocuous choices: to have kids, drive a car to work, keep their job, solve the short-term problems first. When you reach the point at which even the most trivial acts are punishable by the death of the species, then obviously, obviously, you're at a critical juncture, a different kind of point of no return.
