okay. so John Searle doesn't believe that it is
OO possible for machines to become intelligent. one
OOOO of his arguments is the "simulation isn't real"
OOO O argument. it goes something like this. i think.
OO first Searle acknowledges that computers can
O simulate physical systems. like molecules making
OOO O O a gas. or planets rotating about each other. or
OOO the weather. or the neurons in the brain of a
O O human being.
O BUT he says - this is merely a simulation. like
when a computer simulates a plane flying through
O O the air. sure, he says, inside the computer the
OO plane is flying - but it can never, ever, carry
OO OO passengers from new york to san fran. that's
O O the difference between a simulation and the
OO real deal. and the same is true when a computer
OO simulates a human's brain. it may act like a
O O human - but it's not the real deal. it has no
OO O real intelligence.
O OO O okay. well. i don't agree. consider.
OO what if we dig-up Beethoven. we get his genetic
OO code. we get the genetic code of everyone alive
OOO O during his life. we get the plans for all the
OOO O buildings, all the forests, EVERYTHING on the
OO planet earth the day that Beethoven was born.
O O and we simulate it.
O OO OOOOO (yes, this is a very nearly impossible task.
O OOO certainly entirely impractical. but we're
OO OO conducting a thought experiment, so such things
OOOOOO are allowed.)
OOOOO now we simulate the entire earth, from the
O O OOO moment of Beethoven's birth. is the simulated
O O OOOO Beethoven intelligent? (nevermind the other
OO OOOO simulated people living with him.)
OO O O
O OOOOOOO Searle says no. yes he looks like Beethoven
OOOOOOO (well, inside the computer he does, anyway.) and
OOOOOOOO he acts like Beethoven. and he composes like
O OOOOO Beethoven. but no - the real Beethoven existed
O O OOO long ago - this doppelganger is merely walking
O OO OO in the original's footsteps. nothing original.
OOO OO O nothing truly intelligent.
OOOOO OO um.
OOO O OO
OOOOOOOOO well, it is a simulation after all. what happens
OO OOOOO if i pause it for a moment, step inside with
O OOOOOO my digital scalpel, and cure the simulated
O O OOOOOO Beethoven of his simulated syphilis.
OOOOOOO now - when the simulated Beethoven finishes his
OO OO OOOO 9th symphony - he doesn't die. he (and the rest
OOOOO OO of his slightly modified world) continue on. he
OOOOOOOO writes his 10th symphony.
O OOOO OO
O OOOOO i want to know (and Searle, if you're listening,
OO OO O and i've piqued your interest, do write back)
OOO why this 10th symphony isn't an intelligent
O OOO OO O work.
O OOOOO O
OOOOOOOO O i, for one, would love to hear it.
O OOOO -k
