I think the argument is that an amateur with copilot is going to stay an amateur longer than someone without copilot while simultaneously only helping them create something no one--including them--should rely on: it teaches the wrong habits and helps with the wrong problem.

This is good way to put it.

Another way: copilot is a crutch. It may help you move about but if you get too comfortable with it you are never going to learn to run.
