Ah, just like the "roboticisation" of Japan solved their problems with low birth rate, their lack of people available to care for the elderly, and got them out of their decades-long economic funk?

Um, no. China will have one-third of its population aged 60 or older, and - surprise, surprise - we older people (I'm 58) do NOT want to be cared for by robots in our golden years. We want human beings around us, preferably family. And this fact is going to place a great deal of pressure on younger Chinese couples - and especially the wives - in the future.

Also, no, China's not going to implement 'full communism' by 2050, or ever. Communism - like its polar opposite of libertarianism - sounds wonderful in theory, but cannot be implemented on nationwide scales. Why? Because in order for either to be successfully implemented, all (or almost all) the citizenry must be of the same mindset. Neither system allows for the insanely-wide range of mindsets of any large population of human beings.

And that, sir, is why there never has been a truly communist nation. There's always humans who lust after riches or power or privilege, and these will always do what they can to take power without regard to laws, customs, or tradition. This is how Stalin and Mao and Kim and Castro and every other dictator in every allegedly-communist nation took power.
