Why would anyone want to become a Chinese citizen? How's everyone discussing linguistics while completely ignoring the authoritarian elephant in the room?
Tech people need to reduce complexity to make it computable, that's our job. Our strong points are the weak points too. Again: no blame or shame. Just wanted to point out we are susceptible in these matters.
I would think for most people, you care about whether you can fit economically before you consider something that is unlikely to matter.
Obviously don't go and try to immigrate to China if you are planning to be a political commentator.
But for most people in most places, what will you notice? Are there jobs, how is tax, are the streets clean, are there homeless people, can I see a doctor, is there a lot of paperwork? Will I find friends?
