It seems to me, this book is more relevant today than ever. Orwell might have erred with the date, but I think he didn't with the direction of human kind.
Freedom and opportunity?
Opportunity might be true in some areas (particularly IT), but not in other areas. Just because you think you are king, you are not!
Freedom, no, not at all. Democracy has brought much freedom to the people and after the 2nd WW freedom lived up to it's maximum, it seems to me. But in the last decades it declined rapidly.
Do you mean, freedom in Iraq? Or in Afghanistan or other Arabian countries? Think twice! There might be some countries, yes, but they are far away from being real free.
Freedom in western countries? Europe?? The US???
Think again! Just think!
For instance, consider the Chinese version of NSA, it is an ideal tool for a free economy (i.e. a working economy) with control of the population. The country has already got a capitalist economy married to a dictatorship. We expect China to open up and democratize, now that it is getting better and the average education is increasing. But what if the communist party instead starts to integrate with the military, increases automatic surveillance and goes the other way? "The future as a foot that stamps in a face" (iirc from 1984) might seem lika a nice scenario for quite a few guys in boots.
Will it happen? Afaik, the risk is small. But it certainly exists.
Not really.
What do you have in mind? I was thinking about it, but could not get anything fixed to 1984 that could make it a relevant date.
It was about "The year is 1984, and history has led us to this point."
