Computer Science is the purest science

It's the only system that can use itself to prove itself

As The Abelson mentioned in his famous lecture, Computer Science is a rotten name for the field, as we don't really fully understand yet what we're trying to do yet.

I believe in future generations, whatever becomes of Computer Science, and computation in general, will be regarded as the most important and fundamental of fields, more fundamental than physics or mathematics. After all, the Universe is starting to look far more computational in nature than anything else, and mathematics is merely a fuzzy Human language that captures abstract declarative concepts from the computational processes of our own minds, which themselves have emerged from the computational chaos of the Universe over the millennia. The only reason there appear to be mathematical truths is because there are computational truths.

Mathematicians are the ones following a religion and are the ones unable to see the forest for the trees.
