I think we all agree that even if a million monkeys typing on a million typewriters generated the paragraph above, it wouldn't make the Hal who wrote it real. Only Hal's brain or a simulation thereof - being instantiated - can put actual qualia behind the statement. It's not enough to have the inputs and outputs in a Giant Lookup Table. So the question is, if the playback was generated by random chance, can the Hal it "records" be said to exist? Will he ever, even once, have said "cogito ergo sum", or is there only a text-based representation of the words? For the purposes of this argument we are *assuming* that an actual neuron-by-neuron simulation would make the Hal real; the question is, *given* that, does a randomly generated recording also make Hal real?
