Anatomically modern humans who were modern humans in every respect and most likely even had more cranial volume than the average human today have existed for 100 000 years. These people had full capacity of language and all the intellectual capabilities of modern men.

The overwhelming majority of human beings that ever lived never knew such a thing as "technological advancement" they were born and died with exactly the same level of technology. The overwhelming majority of humans were hunter-gatherers to begin with with farming itself being a very recent innovation.

That's just crazy. These people were genetically identical to us. If one were transported to the future at infancy and raised here adopted, it would just grow into a normal human being with no one being able to tell that it was actually born 100 000 years ago and transported to the future, that'a crazy.

All these sudden vast advances of technology are just the product of human beings multiplying and clustering close together in cities which allowed such acceleration of innovation. If society were hit by a nuclear war and all knowledge were lost and the human population were completely decimated, it would take 100 000 years again for men to rebuild to this level of technology.

Billions of humans weren't alive and being born in prehistory.

>100 000 years again for men to rebuild to this level of technology.

Knowing what is possible and having individuals with a modern skillset and written records could accelerate this to a relatively short period of time

Yeah that long breach was broken the moment we discovered writing. You could argue it would be even shorter if internet, the information era, was effectively preserved but that's hardly the case in your common doomsday scenario

>>81939282
Yeah but how do people write if all technology be lost including how to make paper or other writing utensils.

Are people really going to carve all that knowledge in stone and how many people have that knowledge really?

>>81938479 (OP)
yeah and you have to thank high IQ autists for all that technology
