Humans didn't need much technology to live in deserts and tundras. But what if they run out of earth metals to cycle? What if they can't build sustainable energy sources? Our top modern "tech" lasts a couple of hundreds of years before totally collapsing. Humans will eventually go back to simpler tools, be it 10 million years or 100. I give it a couple of hundred thousand.
- simonh 6y agoWe’ve essentially built the entire modern world in a bit over a century. The only way we’ll run out of metals to recycle is if we shoot it all out into space. Otherwise it’ll still be here in one form or another. I am concerned about the long term sustainability of our current phase of civilisation. I think our current way of life is largely doomed, but we will develop new ways of life. Tens of millions of years is a long time. Who knows?
