Nobody is debating the usefulness of GPS versus a paper map. Obviously the paper map was worse. The point is precisely that because GPS is so much better than maps, we delegate all direction-finding to the GPS and completely lose our ability to navigate without it.

A 1990s driver without a map is probably a lot more capable of muddling their way to the destination than a 2020s driver without their GPS.

That's the right analogy. Whether you think it matters how well people can navigate without GPS in a world of ubiquitous phones (and, to bring the analogy back, how well people will be able to program without an LLM after a generation or two of ubiquitous AI) is, of course, a judgment call.
