So what is, the skill in question is thinking critically. Letting that atrophy is kind of a bigger deal than if our paper map reading skills atrophy.

Now, you could argue that, when we use AI, critical thinking skills are more important, because we have to check the output of a tool that is quite prone to error. But in actual use, many people won't do that. We'll be back at "Computers Do Not Lie" (look for the song on Youtube if you're not familiar with it), only with a much higher error rate.
