The Moore law is more a doubling each 26 month. Actually the typical
calculation
time is about 2-3 month. A three year computation would meam number in the
over
with N>20 000 000.
I my own opinion we are finishing the number slower than the progression of
the
computer power. Therefore we should never reach this cross-over.
