AI Crosses a Threshold That Earlier Writing Tools Did Not

The Gist

A spell checker does not speak for you. A model that writes the sentences does. That is why it is not just another writing tool.

Conclusion

The continuity defense fails, and the distinction between assistance and substitution can be stated as a criterion rather than asserted as an intuition.

Premises

  1. The standard defense of AI writing is continuity: it is the latest in a series of tools running from the word processor through the spell checker.
  2. Those tools operate below the level of authorship. A word processor accelerates typing without altering the writer's wording, and a spell checker corrects errors without composing on the writer's behalf.
  3. A language model does alter wording and tone, and it produces text that the reader cannot separate from the author's own formulation.
  4. The relevant test for whether a tool requires disclosure is not novelty or automation, but whether it speaks in the author's place and blurs the boundary between the author's position and the machine's elaboration.
  5. Language models fail that test in the case at issue while the earlier tools pass it.
