The last 50 years is a wild take considering thats the time in with the computers became a bigger thing, mobile phones, smart phones. CRISPR, mRNA Vaccincs, HIV Antivirals, HPV Vaccines, We friggin confirmed the Higgs Boson and Gravity Waves. Found thousands of other worlds outside the solar system. Lithium Ion Batteries, the modern solar panel making solar power the cheapest energy source in most of the world. Blue LEDs making RGB LEDs a thing. Reusable Orbital Rockets.

Where in the fuck did we stall out?

If life is a exponential curve, the moment we stopped overproducing exponential energy and ate the planet up for this.. that was when we stalled.
