OK, so you take the whole simulation (with an agent that can count) and run
it on a system that is Turing-equivalent (I used an abacus above; a counter
machine is Turing-equivalent and resembles an abacus). This running can take
one of three forms: (a) the TM designer physically manipulates the machine;
(b) the TM designer writes out a program and has an ignorant person who can
follow instructions manipulate the machine; (c) the wind happens to
manipulate the machine in the same way as the human would have. Does the
program run and counting occur in each case?
