My friend Landon sent me the link I needed to say "math proves that math is
equivalent to programming"; it actually says something more like "there is
an isomorphism between proofs of deductive logic and constructions of Lambda
Calculus" but even that I'm saying badly, the link is
http://en.wikipedia.org/wiki/Curry-Howard_isomorphism
Gratifyingly, the intro has the phrase "Proofs are Programs" :-)

On second thought my guestimate of the size of a program that might be
produced from the Clasification of Finite Simple Groups is excessive. I'm
thinking 100MB would be more fair order of magnitude than 1GB.

I don't mean that the possible huge size of source code justifies 64 bit
words, it's enough, to me, that a huge integer can fit into a register, for
number theory. But yes we humans can indeed create vast grotesque edifices
of scholarship without the necessity of machine generation.

But the machines will, of course, win in the end :-)
