For me it is the fact that our blood contains iron. I earlier used to believe the word stood for some ‘organic element’ since I couldn’t accept we had metal flowing through our supposed carbon-based bodies, till I realized that is where the taste and smell of blood comes from.
The USA has 157 million workers, shuffling 140,000 years of work a day. One in 4 has an idea. One in five of those is a good idea. Two thousand stakeholders can make it an innovative idea. So, they can pump 3.5 years of brute force innovation into the world every single day. That’s well over a thousand years of advancement per year.
Critical mass populations that can keep up with their own development are a serious creative force to be reckoned with. And human evolution has been exceeded by innovation, dramatically.
But thousands of years of experience die off every day too.
