The World becomes more unpredictable

Recently, I read a lot of news and I find that there are a lot of changes happened in the World which are not predictable at all in the past.

For example,

– the decline of Japan electronics corporation

– the so called Keynesian economics theory seems to be outdated

– Hong Kong’s life expectancy is the highest in the World despite of its stressful environment and the highest population density in the World.

What I find is when there is one new thing coming up and become a dominating force, then the prediction of existing theories will become invalid.

If this is true, then what a the waste of life for us to study so many theories in University.
