Many factors limited the continuous progress and development of human science and technology. Three very important points needed to be met.
First, technical barriers.
Technical barriers did not simply mean that a certain material or discipline had reached its limit and could not be broken through without the help of external forces.
Rather, it meant that the knowledge was too unbearable for humans to carry out more in-depth research.
A very simple example would be if civilization returned to the Stone Age like the basin, then only 100 hardworking and intelligent people were enough to push forward the technological progress and manufacturing capability of the civilization.
These 100 people would need to learn how to build stone tools, houses, and hunting and make corresponding upgrades to them.
It was not hard to find these 100 people if you had a population of 1,000,000 at most.
