I find it impossible to pretend to have any idea what the world will be like 100 years from now.
All I have to do is pretend that I lived 100 years ago and ask myself the same question. What will the world be like in the year 2000? The world has changed so much in the last 100 years. Advents in technology alone have been absolutely incredible. I can't even begin to imagine what will come in the 100 years to follow.
