Sounds like you don’t even dispute his point, so how could you have refuted it?

To your point about relevance : nobody here has claimed this competitive advantage is wildly useful in a “first world” context, something the GP actually framed explicitly.

Personally I don’t think one needs to invoke post apocalyptic scenarios, as there are plenty of “first world” professions or scenarios that benefit from the same skill sets - military, emergency medicine, firefighting, just to name a few. The first world isn’t all spreadsheets and jira tasks.
