I often am critical of Krauss when he speaks out of his element.
   He has a scaling problem with certain topics.

   That being said, in this article, Krauss is at his best and it
   is a well written piece, albeit it can be summed up as, "We can
   only work with what we can work with and chasing the dream of
   comprehending everything requires some sacrifice of actually
   comprehending everything".

   More or less. Disagreement welcomed.
