Valuable -- likely vital -- cooperative know-how for hugely changing the world has been LOST to the sands of time. (94%) Likely examples include the Manhattan Project, the Apollo program, genuinely uplifting colonialism, building the pyramids without epic hardships or complaints.

Much of this know-how was even widely applied during the lifetimes of some now living. Our simple loss of such important knowledge flies in the face of deep assumptions in the water we all grew up in: progressivism, that knowledge is always increasing, that at least the best First World cultures since the Renaissance have always moved forward.

There are world-changing status-move tricks seen in recent history that no one of consequence uses today, and not because they wouldn't work. (88%) Top-of-the-First-World moderns should unearth, update & reapply lost status moves for managing much of the world. (74%) Wealthy, powerful rationalists should WIN! Just as other First Worlders should not retard FAI, so the developing world should not fester, struggle, agitate in ways that seriously increase existential risks.
