If there's actual evidence that quantum determinism is a requirement, then that would have been a valid argument to make instead of the Chinese room one. If the premise is that "it ain't sentient if it ain't quantum", why even bother with such thought experiments?

But there's no such clear evidence, and the quantum hypothesis itself seems to be popular mainly among those who reluctantly accept materialism of consciousness, but are unwilling to fully accept the implications wrt their understanding of "freedom of will". That is, it is more of a religion in disguise.
