Lee Sedol said something like a human player would need three days of thinking time vs the CPU. However it's no different than human vs car. Any car can do 300 km in 3 hours. A pro probably can do 300 km in 3 days. The different time allowance makes up for quantitative differences in hardware.

Sometimes there are also qualitative differences, no human can fly or dive very deep or go to the moon without the assistance of a machine. I don't know if there are qualitative differences in go and chess, like no human can win 60-0 against fellow pros or get to 3400 ELO despite a very large time allowance.
