The author is patting themselves on the back a bit, and with regard to the painter, discussed in the closing sentence, loses sight of other non-written communication. It’s the broad strokes - in any form - that drive the largest impact. Indeed, the quality of writing does “taper with the level of interaction needed”, but in the opposite way described. As a middle manager, writing is critical for conveying all the necessary information. Get the work done, this way is right, and at the highest speed! At the highest levels though, it’s less useful - though exceptions to the rules (e.g. Warren Buffet using his soapbox to great effect) do exist.
