We are in a race to cross a very dangerous zone, between where we are and where our grandchildren may be. Will they will know how to manage the planet? How to expend beyond the planet? How to stay calm? How to argue in a fare and decent way, bypassing politics? this isn't a vast utopia, it is just us, much more reasonable, having raised better grandchildren. in order to get there, we have to get past all these pifalls. We have already got past the one called the nuclear war, it is pretty impressive. There are so many others along the next twenty, thirty years, that is our job. And if we make it,we might be the fist intelligent life form to make it.
