Would Descartes have said that modernity is infantilizing? I'm not advocating the Whig theory of history, which says that the present is better than the past in all ways. You can look at the advantages and disadvantages of any society.
But theocratic monarchies are infantilizing in different ways than individualistic societies. The peasant's assurance about Christianity contrasts with the underlying nihilism of modern Western cultures in which consumers are trained rather by large cynical corporations.
I'm not familiar with most of the references you provide, but I'm sure there's much complexity to be found in premodern cultures. I still take the Scientific Revolution to be paramount, though, because it objectively expanded our understanding of nature.
