My assertion is glib, but your response is wholly insubstantive. Can you to point out how this piece treats Rego as an actual example of a real-world Datalog? I don't see any link when mentioning real-world Datalogs. The fact that this piece makes no mention of it but provides a drive-by link to it suggests that the author is not actually interested in evaluating the problem in a realistic scenario. The piece the literary equivalent of a reminder that one can harm oneself with a gun without ever actually discussing how one should implement gun safety.
