The inscription on the (now destroyed) “Georgia Guidestones”:
Guide reproduction wisely – improving fitness and diversity.
Unite humanity with a living new language.
Rule passion – faith – tradition – and all things with tempered reason.
Protect people and nations with fair laws and just courts.
Let all nations rule internally resolving external disputes in a world court.
Avoid petty laws and useless officials.
Balance personal rights with social duties.
Prize truth – beauty – love – seeking harmony with the infinite.
Be not a cancer on the Earth – Leave room for nature – Leave room for nature.
“Maintain humanity under 500,000,000 in perpetual balance with nature.”
A point I’ve made before is that this population level will support the level of technology and longevity that the world had when it was last at this level, the level of the 14th century.
Most of the world will revert to subsistence farming. It takes around 6 to 8 billion people for the world to have, among other things, iPhones.
