That is cool how they knew to hedge future costs back then. I'm convinced we've been the same for like 10k years and any biological evolution we've had over 100k years or so came in sudden spurts due to evolutionary bottlenecks from whatever causes, not a steady rate of evolving
Definitely. I don't think we've evolved at all since then. If you look at how we measure our early progress, it's through our use of metals - copper age, bronze age, iron age.
We've been measuring human advancement by finding new ways to dig up and harness stuff in the ground. Even today I would say that hasn't changed. If we use an iPhone as the benchmark for technological progress... it's got at least two dozen different elements in it.
Maybe if people knew how to dig up and refine all those elements in 5000 BC, they would have been capable of producing the advancements we have today. And on the other side, today is not that different from ancient times. We still need sewers and concrete, and the Romans hacked that pretty long ago.
We also still need to wait for crops to grow, so it still helps to have insurance that they'll fetch a fair price
