to the 1 million input configuration of 1 million bits right and for each of those 2 to the 1 million configuration you have one output bit that's the truth table of a particular boolean function ok so the number of configurations of 2 to the 1 million bits is 2 to the 2 to the 1 million it's an adorably large number I mean it's just a ridiculously large number now among all of those functions how many do you think what proportion do you think your brain can actually compute your visual cortex visual cortex has you know order between
