Nick (sorry), great article.
There are a few things we “know” about the future: population growth will continue exponentially, the processing power of computers will get faster, smaller, cheaper (despite the thermal transfer barriers of silicon), the world will be simultaneously fracturing and homogenizing (Jihad vs. McWorld). Natural resources will become scarcer. Corporations will gain more power.
Other than that, I see the future as a blank page. I say, write your own.
