Some advancements specific to the PRC:

• The elimination of city-poverty.
• An attack on rural poverty that’s lifted more people out of extreme poverty than any country in world history.
• Upcoming fusion power
• The Chinese space program that’s likely to land people on mars within a few decades.
• The ubiquitious payment systems and apps that can even let you book doctors appointments.
• Digitally connected cities with 5g.
• Ubiquitous and affordable health care.
• The most high speed rail per capita.
• Lots of up and coming natively developed tech like CPUs and wireless that for years have been controlled only by western powers.

All of these point to what’s possible when you eliminate capitalist’s control of the surplus.
