I don't see this happening. People learn wordy prose in education: an assignment requires certain amount of words, but the student is either unwilling or unable to come up with information-packed content and resort to padding with fluff. Some become copywriters, some middle managers, some HR. Eliminating fluffery makes these positions, built around wrangling as much written word as possible, suddenly obsolete and consequently people, because writing well masked fluff is their main marketable skill. There's very strong feedback loop working against information dense written word.
