Once again ignoring the setup of the argument. The solution to the chinese room isn’t “the trick is to wait long enough”.
I don’t know why you want to argue about this given you so clearly reject the entire concept of the thought experiment.
I find the entire thing to be intellectual wankery. A very simple and ethical solution is that if two things appear conscious from the outside then just treat them both as such. Job done. I don’t need to find excuses like “ah but inside there’s a book!” Or “it’s manipulations are on the syntactic level if we just look inside” or “but it’s just valves!” I can simply not mistreat anything that appears conscious.
All of this feels like a scared response to the idea that maybe we’re not special.
