I’m sure that many people in disparate places around the globe invented the bow and arrow and the arch and column form of architecture but they were statistically a tiny fraction of the population.
Once those ideas were shown to a given population they may have been refined but the underlying idea was simply copied over and over again.
Almost everything anyone knows today is due to an accumulation of knowledge over tens of centuries. Real “out of the box” breakthrough ideas are still incredibly rare.
We all stand on the shoulders of giants. Its been said and its true.
A book I can highly recommend is “Where good ideas come from”.
It has the idea of the near adjacent. Most great ideas are the next door over if you will. Very few ideas are way out of time and if they are then their is no way to implement them.
He gives the example of a scientist (Pascal?) speculating about computer programming in the 1600’s. Of course he had no way to implement his idea.
