I dont take the Peace and literature nobel prices
very seriously.
Writing some "social critic" book is not the same as
making a scientific breakthough in physics or medicine.

(Obama is a good example of that. He
should not get the price currently, He might be elegible in the future
though, given what he can really move in the peace process.
You also dont give that physics nobel price for "is smart, might find
something interesting in the future")

They should rather establish Nobel prices in mathematics and computer technology.
