Anything else aside, I wouldn't be so critical of the thought experiment. It's from 1980 and was intended as an argument against the thought that symbolic manipulation is all that's required for a computer to have understanding of language.
It being a thought experiment that examines where understanding originates in a system that's been given serious reply and discussion for 43 years makes me feel like it's not ridiculous.
