Pretending like computers can do the job of a person is not that much sillier than pretending a poorly paid proctor who doesn't care can do the job of a professor is not that that much sillier than pretending a class grade is sufficient to certify somebody's knowledge is not that much sillier than pretending a written test can do the job of a one-on-one evaluation.

But each step is more "efficient" than the previous one. It's just that each one is also less effective.
