It's not, and unfortunately you cannot just dismiss perhaps the greatest refutation of functionalism as being incoherent, you have to actually address the argument. Take a person (Fred) with no experience of knowledge of chess. They don't know how the game works, how the pieces move, or any of the rules. They memorise an algorithm, say how Leela does its search and evaluation, and they can then look at a position on…
There is no algorithm that can be memorized. Leela's understanding is in the weights, not neural net algorithms. I'm familiar with the Chinese room argument and I've never accepted it because what it describes isn't real. It imagines some algorithm for which there is no evidence. Show me this process running and then ask me if it understands Chinese. To me this is as philosophically dubious as the notion of p-zombies…
If you did see the process running, when asked would you say it understands Chinese?
