If this is right, then once we know enough about the brain, one second of supercomputer time should be able to simulate one second of brain processing. If technology advances at anything like its usual speed, we can expect computers to speed up by a factor of ten every decade, or a factor of 10 billion (1010) over a century. That suggests that within a century (at a speed of 1026 flops), a second of computer time will be able to simulate 10 billion brains for a second each. Within another century (at a speed of 1036 flops), a second of computer time will be able to simulate 10 billion brains
