The Universal Turing Machine format is designed to encourage writing as a mode of thinking, which is what the arts – seeing, listening, writing, reading – have always offered. A memory that knows it’s being remembered is up there with the hardest, cleverest kind of thinking we can do, and why, for the purposes of his test, Turing couldn’t keep his hands off literature. AIs can’t yet emulate writing as its own mode of thinking, or reading, or remembering, and it doesn’t help to learn to write by reading everything. Just as memoirs aren’t improved by total recall.
