The argument, as I can gleam from TFA, is as follows: Since a human mind is equivalent to a Turing machine minus infinite memory, and a human is capable of using outside tools to expand their own memory arbitrarily, it's impossible for a Turing machine to be "more intelligent" than a human, since a human could, given sufficient time and external memory, execute the same program that machine executed and arrive at the same result.
