I have discussed what I think are the primary reasons in this story and criticized some other theories I often see such as Mongols stopping industrialization or China not being capitalist enough.
did they came up with the gunpowder because they were capitalist enough but Europeans not?
Fusion energy R&D is mostly funded by governments, is it because the world is not capitalist enough?
the semiconductor industry is dominated by Asia, does that mean that EU/NA is not capitalist enough?
saying something "isn't capitalist enough" is disrespecting the people who actually dedicate their life to research
