about to say as someone who has spent time in both cities on multiple occasions... wth are they talking about? The pollution in NYC doesn't make it hard to open your eyes when a low-pressure system comes in.

I have been visiting Shanghai since 2006, and the changes have been enormous every time I go back, it's a great city, lots of cool and interesting things to do, but IMO New York is still another level above it. I guess if stone age = not every building having day glow light shows going on 24/7 then yes.
