Meghan Cox Gordon likes the idea of typos in finished products.

If there’s a goof, you know the author is human. Writers who compose using their own eyes and brains (and fingers) are going to err. Machines that collate and disgorge synthetic blocks of text, or that comb through human-generated text for usage mistakes, are not.

Not so. AI will learn to introduce typos and mistaken phrases entirely separately from its “ordinary” hallucinations. Dishonest writers and plagiarists will inject typos and mistaken phrases in attempts to disguise their own dishonesty.
