> AI writing will make people who write worse than average, better writers.

Maybe it will make them output better text, but it doesn’t make them better writers. That’d be like saying (to borrow the analogy from the post) that using an excavator makes you better at lifting weights. It doesn’t. You don’t improve, you don’t get better, it’s only the produced artefact which becomes superficially different.

The point of the article is the thinking. Style is something completely orthogonal. It’s irrelevant to the discussion.
