war between
competing
algorithms trying to outguess each other then this can be interpereted in the 
ordinals.
But I can't believe
that a competent mathematician and programmer who understands this concept and 
ordinal
notations
up to, say, Gamma_0 will gain any insight useful in financial practice from the 
more
arcane systems
of ordinal notations."
