I think more people will begin to marry into other races and religions (which will result in more biracial people), majority of people in 1st world countries will be Atheist or Agnostic, bikes will be used more rather than cars to be more ecological and because of the soaring gas prices, poverty will go up by a much higher margin, the Internet may go through phases and play an even bigger role in daily life, technology will become everything in our daily lives, the amount of families will decrease, climate will be even warmer than it is now, North Korea could go to war with the South by then or even before, Scotland would no longer be a part of Great Britain, and so many other things I predict to happen in the next coming years.
I think it's exciting to think ahead. Who knows what the future brings!
