The 6 current categories seems not to be the right ones for greatest honour in contemporary world. Is better physicists, chemists or economists what we need most? And what about the winners of the peace prize, did they deserve it?
Are authors that important today, compared to many other artists?
One example of a "missing prize" (it may exist, but rather unknown) - this prize should clearly be the most prestigeous: An environment award.
Instead of "advanced" medicine the prize may better go to "health" in a broader sense. The prize in economy (as far as I not really not created by Nobel, but swedish bank)should instead go to research in "human needs" (what we need to live a "good life") - if such a category could be properly defined - perhaps it should just be remkoved?
And one can ask if physics or chemistry is more important or honourable than many other academic disciplines.
