I think there has always been lots of stupid people. It's just that they haven't had the Internet to show everyone how stupid they are until recent times.
In 2012, the aliens (or possibly humans from a parallel universe) are coming to collect the gold we have been mining for them! I have not yet determined if they they will permit us to live beyond that point. Who knows what will happen after that..... I hope they take off with the gold, but leave us with new technologies. There are so many exciting technologies 100-200 years out, and I wish I could live to see them =(
