The billionaires considered using special combination locks on the food supply that only they knew. Or making guards wear disciplinary collars of some kind in return for their survival. Or maybe building robots to serve as guards and workers – if that technology could be developed “in time”.

The way to get your guards to exhibit loyalty in the future was to treat them like friends right now, I explained. Don’t just invest in ammo and electric fences, invest in people and relationships. They rolled their eyes at what must have sounded to them like hippy philosophy.
