In the same way you might use Google Maps to get everywhere and not know how to get there otherwise, AI might cause people to stop learning things they would have otherwise had to learn.

The argument makes a lot of sense to me but this particular example somewhat falls flat. When I started my new job, I used Google Maps to learn the optimal route for a couple days until I had it committed to memory. Then I didn't need it anymore.

For a place I am going to exactly once and then probably never again however, why would I want that information to take up valuable brain space? In a pre Google maps world, you spend probably twice as long taking a less optimal route that goes in that general direction, then driving around the area for a bit longer until you hopefully stumble upon what it is youre looking for.
