Yeah I suppose that is the other side of the coin. Knowing about functors makes it easier to intuit what utilitu functions to write to avoid boilerplate. But sometimes the 'mysticism' gets in the way, this article spends a lot of words on technicalities but very little on the intuition that this should be fairly trivially true. This might make sense in the context for which this article is written, but why this article is on the front page of HN I don't understand.
