<p>A sequential computer program could simply be a loop that sampled random numbers and indexed into the address space of the computer program itself (not its memory). One could make a specialized computer using a FPGA that even had an instruction to do that
random dispatching. To counter the arguments of Penrose, one could do the same using quantum states.<o:p></o:p></p>

<p>There are all kinds of physical processes that are simulated on classical supercomputers, of course.<o:p></o:p></p>
