This is a very weird list. I'll just comment on the places I've lived and worked in:

- Why is Hong Kong even on the list?

- Sydney and Melbourne: expensive; Internet is both low bandwidth and high latency; lack of travel destinations due to distance; poor air quality due to excessive use of fossil fuels and bushfires (yes I checked, nowadays average air quality across Melbourne is worse than HK); toxic politics. Not to mention lots of unpaid overtime. Why are they so high on the list?
