That's true. They do better-prepare an applicant for a job that filters on a person's ability to accomplish arbitrary things in a vacuum that is completely disconnected from the real world.

That's probably a good thing to filter on for, say, the navigation role on all kinds of crafts (from land to sea to space). There are naval roles where navigating with a sextant and memory is an important skill to have, and to test for.

But that operating-in-a-vacuum skill doesn't relate well to roles that don't need to exist in a vacuum. In most of the jobs in the real world, we get to use tools -- and when the tools go out to lunch, we don't revert to the Old Ways.

When an accountant's computer dies, they don't transition back to written arithmetic and paper ledgers. Instead, someone who fixes computers gets it going again, and they get back to work as soon as that's done.
