EDIT: 6. is bad. It would exclude equally many actual AI and blind people as well.
So we wouldn’t use blind people in the human control group. We’d want to get rid of any disabilities that the AI could use as an excuse (like the whole 13 year-old foreign boy).
As for excluding AIs… the Turing test was conceived as a sufficient, but not necessary, measure of intelligence. If AI passes, then intelligent, not the converse (which is much harder).
