So, the point remains, knowledge based economy, while certainly useful, is not the only way for an economy to grow. Sheer hardwork can be an immense force too, that's what the chinese did over the years and what this article points to as well.

China did it when world still needed humans to do lot of manufacturing which is changing very rapidly. In fact, India's manufacturing sector is not adapting lot of automation just to make sure they can capitalise human effort which may be cheaper now but may not be in future ( just like in China)
