My butt has been a butt for a few decades now, and I don't have to listen to a thing it says. Perhaps mere duration does not automatically imbue a practice, habit, arrangement, or person with value and wisdom worthy of preservation.

If we came upon the idea today, and someone told me they had memorized a ton of streets, could sometimes do marginally better than GMaps, and therefore deserved to be paid a major premium over what GMaps could do, we would be skeptical of the cost/value tradeoff. Except, perhaps, as a luxury service for the upper crust.
