…At that time [the 1960s], Bell Laboratories scientists projected that
computer speeds as high as 30 million floating-point calculations per
second (megaflops) would be needed for the Army’s ballistic missile
defense system. Many computer experts — including a National Academy
of Sciences panel — said achieving such speeds, even using multiple
processors, was impossible. Today, new generation supercomputers operate
at billions of operations per second (gigaflops).
