If a task (like accounting) can be codified to a set of fixed rules, then it should be automated, because computers are better than us in memory. I do agree that one should look at #AI (ie. not rule-based) outputs critically, because memory recall does not translate into performance in unknown situations, but I do have doubts whether the failure to do so can be simply framed as "#skill erosion."
