How will the world be different in 20 years from now?

In my perspective, the world will be much different then today's for many reasons. Here are some changes:
1) Computer's will take over many jobs
2) Gas prices will be at least 5$
3) The world will be knee deep of old people
4) I will once again the a red head
5) Michelle may rule the world
6) Diana will have her own magazine - DARE
7) Architects will build over buildings
8) Most of the population will be needing glasses due to the fact technologies will have taken over
9) California will most likely be flooded
10) There will be less countries because more countries will merge together to survive
11) A lot more diseases
12) Species will die because they won't be able to adapt to global warming changes.

In other words, the world will SUCK.
