There are other factors that may encourage artistic and scientific advancement. The peace of Edo era in Japan (1603-1868), and a Samurai class that had no wars to fight anymore brough many artistic, cultural and scientific inovations.
The Japanese of the era had relativelly high literacy rates, developed mathematics and astronomy (sometimes discovering principles slightly before Europe [1]). The Japenese were also fond of Dutch science books on mechanics and medicine, and were more adept in using firearms [2] than it is usually assumed.
When Europe and the US, now with industrial revolution technology levels, began to harass Asia, Japan was able to modernize quickly and even defeat Russia. But this was only possible because Japan had their own "mini Renaisance" of sorts in the Edo era.

That's an important point. However, what was important over the long-term is what the West did with that new wealth, namely feed a significant portion of it into helping the self-propelling dynamics the article describes.
The other civilizations, in contrast, had self-perpetuating dynamics that prevented growth and technological progress beyond a certain level, as least for the most part.
