These are always fun thought exercises. IIRC, Sapiens had an example if someone fell asleep in 1000 and woke up in 1500, they would still recognize the world. B

These are always fun thought exercises. IIRC, Sapiens had an example if someone fell asleep in 1000 and woke up in 1500, they would still recognize the world. But if they fell asleep in 1500 and woke up in 2000, it would be unrecognizable. What it seems like we're seeing is the compounding of science. Much like how compound interest works. I often wish I was born today just so I could see the progress in the next 50-100 years.
