I've been wondering about this for months. There will come a time in the not-so-distant future where an extremely high percentage of the population will have the ability to kill most if not all of the rest of population. I can't see any way to deal with this except the following. Theoretically, once we get self-sustaining off-planet populations the existential risk is reduced by a massive amount. I see this weird pseudo-utopia as a possibility where families live miles and miles apart, on self-sufficient homesteads, kids and most adults telecommute to work or school, and travel only for social, or entertainment purposes. Have some communal areas, and cities will still probably exist in some form, but keep the vast majority of the population distributed, and hopefully, in a happy fashion.What about when the day comes when everyone has the power to kill anyone else just by thinking about it?
