We need a button like this but it clearly and in common language states the levels of technology and quality of life we can expect.
Humanity globally votes on a spectrum of these agreements until we find a suitable level.
My pitch is; we maintain enough electronic production to keep us all online at a basic desktop computer.
We get one new phone each decade, and one replacement phone should it break.
Other than that, what do we really need? Electricity and farming, a mild amount of houses to be constructed.
We should minimize R&D to things that lower power costs or energy usage/efficiency.
But we don't need a space program. We don't need excessive military spending. We don't need Formula One races, or joy rides in helicopters. We don't really need tourism. We only need a limited amount of mining and manufacturing. We don't need plastic toys.
We need a global shift in culture, lifestyle and cooperation... We need to be the techno-amish-collective.
