And that's not a false dichotomy? If I say which sport is more exhilarating to watch football or basketball? It's not a false dichotomy and it's weird if someone were to butt in with "What about baseball? Why didn't you mention baseball? What about soccer, what about tennis, this isn't a fair discussion!" I wasn't saying and didn't even imply those are the only options they just happen to be the ones we're talking about and it would be absurd to bring in the thousands of other sports to figure out which of the two is more exhilarating to spectate.
Tokyo has been considered a high tech utopia for a long time no one is surprised by its modernity (similar with Hong Kong) whereas China over the last decades has been portrayed as being little more than poor starving farmers and slave labor in worn out factories, and that juxtaposition is what makes it an interesting point of contrast.
Also I did see a barrage of articles praising Japan in the last few decades. There's literally multiple terms for westerners who are obsessed with Japan.
Also if it hasn't been unique to China at all (although I never said it was) why doesn't the country with a similar population and similar location (India) seem to have the same sort of reduction in poverty, economic prosperity, high tech buildings, and extensive modern transportation?
