China has successfully replicated everything internet has to offer and built its own version of it. Google, Youtube, Whatsapp, Facebook, Twitter, Paypal, Ebay and everything else. After duplication these companies have evolved in many different ways. WeChat is the biggest example, one interface is whatsapp + twitter+ youtube+ hyperlocal+ google+ amazon + paypal and has humongous data which in a very scary fashion shared with the govt too.But if chinese apps start to overtake over american apps, all over the world, won't China become the mightiest empire of the world. I am sure, giants in silicon valley must be worried about it.
