I keep thinking about the monkeys in the movie 2001 who didn’t know how to use tools throwing sticks or bones up in the air—until someone accidentally figured out they could use them to kill other folks.
The march of evolution continues to this very day, eh?
As far as the Ancient Egyptians use of tools, today I am of the opinion that an infinite number of Egyptians, with an infinite number of hard rocks, could eventually produce the Serapeum vaults.
The temptation is to look it from the context of a young, vital workforce that only knows how to swipe, or type with their thumbs.
