Ever watch a sci fi movie made in the 1970's. 1980's, or 1990's depicting the world around the present time and laugh at how silly they were? Like flying cars and floating cities. My son always asks how we could get it so wrong. Al Gore made similar predictions a few decades ago about the dire situation we would be in right now. At least they have now learned to project just far enough into the future that none of us will live long enough to laugh at their silly predictions if they turn out to be silly.
