Consider: what would the table contain as appropriate responses for the following questions? (Each question would certainly appear many, many times in our record of all conversations up to length N.)
“Hello, what is your name?”
“Where do you live?”
“What do you look like?”
“Tell me about your favorite television show.”
Remember that a GLUT, by definition, matches each input to one output. If you have to algorithmically consider context, whether environmental (what year is it? where are we?), personal (who am I?), or conversation history (what’s been said up to this point?), then that is not a GLUT, it is a program. You can of course convert any program that deterministically gives output for given input into a GLUT, but to do that successfully, you really do need all possible inputs and their outputs; and “input” here means “question, plus conversation history, plus complete description of world-state” (complete because we don’t know what context we’ll need in order to give an appropriate response).
In other words, to construct such a GLUT, you would have to be well-nigh omniscient. But, admittedly, you would not then have to “know” any Chinese.
I remain dubious.
