Comparable clock rate

Say there’s three clock ticks per machine instruction, and get 3 • 3 • 10 17 cycles per second. I’ll round this up to 10 • 1017 to get 1018, which is a tidy quintillion ticks per second, or one exahertz.

10 18

Table 12: The Three-Hundred-Petaflop Brain as an Exahertz PC

Were Moore’s Law to continue holding good, we could get a billionfold speedup in forty-five years and reach the petaflop-to-exaflop zone of human brain hardware around the middle of the century. So does that mean we’ll have humanlike robots in the year 2045?

Not so fast. First of all, we don’t know how long Moore’s Law will hold up. As of the writing of this book, some pessimistic chip engineers are saying that we can hope for at most another fifteen years of Moore’s Law, meaning that our PCs are going to have a hard time getting much past the teraflop range. But maybe they’re wrong. People have predicted the end of Moore’s Law before, and over and over new technologies have emerged to keep things going.
