The west will continue to move away from unskilled labour so I think there is some drive towards using your brains. Also alot of asian countries tend to be big on education. India especially, alot of people that work in call centres actually have degrees in India.
(If you want to have a call centre with a high level of knowledge (degree based) it really has to be outsource to India )
I'm going to be pedantic and suggest humanity on the whole will get smarter but mainly driven from non U.S countries (The U.S having really carried alot of the progress the last 60 years). Continental Europe and Asia seem to have quite a high education level. I would expect Asian to continue to close the science gap rapidly and maybe over take the U.S.
It is a worrying sign in the west that so many people are overweight. When you have doctors saying your are reducing your life expectancy and they still can't get motivated for themselves or indirectly for their partners or childrens sake that's a big concern. If you can't get people to exercise and eat right to help themselves what hope do you have of getting them to become more educated.
Seriously, is it that hard to read a book a month, that's 12 for the year. That alone would be a help.
