"My response to the systems theory is quite simple: let the individual internalize all of these elements of the system. He memorizes the rules in the ledger and the data banks of Chinese symbols, and he does all the calculations in his head. The individual then incorporates the entire system. There isn't anything at all to the system that he does not encompass. We can even get rid of the room and suppose he works outdoors. All the same, he understands nothing of the Chinese, and a fortiori neither does the system, because there isn't anything in the system that isn't in him. If he doesn't understand, then there is no way the system could understand because the system is just a part of him."
Searle does not seem to understand that the systems reply is not dependent on where or how the components of the system are implemented. He apparently cannot conceive that, while the subject's conscious mind is solely occupied with mechanically performing the operations of the algorithm, the system that her conscious mind is part of actually understands something, and that this would be so even if the system were implemented entirely within the physical body of the subject. It is an outlandish concept, but the premise of the experiment is itself outlandish, and a philosopher should not expect ordinary intuitions to be a reliable guide to what would happen in such cases.
The SEP entry mentions Schaeffer (2009) and Nute (2011) for the line of disagreement extending into a discussion of modality.
Regarding the second line of argument, the entry mentions Harnad (2012) and says that he appears to follow Searle in, "linking understanding and states of consciousness" as well as arguing "that the core problem of conscious "feeling" requires sensory connections to the real world."
The primary issue in all of this is whether certain non-biological systems (i.e. a computer) are sufficient for the understanding generated by certain biological systems (i.e. humans). This has not much of anything to do with physicalism or dualism, no matter what certain responses by non-experts (Penrose, Kurzweil, etc.) would have some believe. The fact that Cole even mentions Kurzweil is, arguably, a disservice to those outside the relevant domain.
The take-away is this: in analytical philosophy, many famous thought experiments are important not for their intended conclusions, but for the expanded dialectic they generate, and which lasts for decades (if not longer). The expanded dialectic brings additional clarity and raises important questions that had either gone unnoticed or were impossible to see before the thought experiment.
There is a small minority of individuals on both sides that seem to want to slow scientific progress (whether intentionally or not). Now, the vast majority of the time it is presumed people like Searle fit this description. People like Dennett fit this description as well, though. Anyone truly making definitive claims about having resolved the question of (say) conciousness, is not taking the right tack from a scientific perspective.
No-one ever disproved vitalism, but its implicit threat to the progress of biology simply dropped by the wayside.
