It's the fallacy of perpetual motion and conflation between a Turing machine that requires net external energy to operate and a passive Rube Goldberg machine.

It's the fallacy of perpetual motion and conflation between a Turing machine that requires net external energy to operate and a passive Rube Goldberg machine. While one can create combinational "logic" out of valves or dominos, it's impossible to create sequential logic out of passive physical objects. Sequential logic takes the form of S-R latches like: -+++++++++++===++++++-. ==::::::::::::::::::::=*- .-==. .. ==::::::::::::::::::::::-*-. .:-=. :#*++++++++++++++++++++++++++++++*=::::::::::::::::::::::::==. .-++. ==:::::::::::::::::::::::::=+ ==::::::::::::::::::::::::::*- ==::::::::::::::::::::::::::-*..::. .... ==:::::::::::::::::::::::::::*-+..==. .:. .:..= .= ==:::::::::::::::::::::::::::*==..-+-:::::-*+::::::::==..=-== ==:::::::::::::::::::::::::::#..--:. .=: .... ==::::::::::::::::::::::::::+= .=: ==:::::::::::::::::::::::::-*. .=: .-+++++++++++++#=::::::::::::::::::::::::-+. .=: .=- ==:::::::::::::::::::::::++. .=: .=- ==::::::::::::::::::::-++. .+: .=- -*++++++++++++++++**+-:. .:+*=:. .=- ...-**-. .=- .-=+=:. .=- :=+=:.. .==... ...-+*-. .:=+=-.. ..-=+=:. ..:=*+:. .:=*=:.. .-*+-.....-+*=.. .+#*#+:. .=*=:.....:=*+:. ...:+*=. .=*+-... ..-=+=:. .:=+=-.. .==.. ..:=*=:. .=- .=*+-... .=- .:=+=-.. .=- ..:=*=:. .=- =*===============++**=:.. ..=*+-. .=- ==::::::::::::::::::::-++. .=: .=- ==:::::::::::::::::::::::++. =: .-+++++++++++++*=::::::::::::::::::::::::-+. =: ==:::::::::::::::::::::::::-*. =: ==::::::::::::::::::::::::::+= =: ==:::::::::::::::::::::::::::#..--:. =: .=++: ==:::::::::::::::::::::::::::*==..-+-------*+--------==..=.:= ==:::::::::::::::::::::::::::*-+:.==.....................+:=- ==::::::::::::::::::::::::::-*. ... ==::::::::::::::::::::::::::*- .=++: ==:::::::::::::::::::::::::=+. .==+: :##++++++++++++++++++++++++++++++#=::::::::::::::::::::::::==. .:..-. . ==::::::::::::::::::::::-*-. ==::::::::::::::::::::+*:. :*++++++++++++++++++=:.
