This does not change my mind - I'm going anyway. It helps that it is being held in Shanghai, which is special by itself since I have not been to that city before. It helps that the Chinese are promoting it in their own particular way, which turns into a touting of the largest world's fair ever. It helps that the theme of this year's expo is about "better city, better life" is all about imagining the world in which we will live in the future, according to our concerns for sustainability and maintaining harmony with our surroundings. And it helps that my visit will coincide with the World Cup, which will give added dimension to the global village (it helps to be outside the US to fully appreciate the grandeur that is the largest sporting event in the world).
I suppose that all the wonders of the modern world will conspire to minimize the joy we can experience in these sorts of cultural exchanges - but I'm not buying. I'm excited about an Expo and curious to join the millions who will find the same excitement too.
