Having been an academic, this article confused two things. The use of jargon is often justified, as specialists often use particular words to encapsulated complicated but also well defined concepts. Having seen the confusion that comes when hidden assumptions are allowed to change (equivocation), the use of jargon will not go away.

The problem that I see is that translating ideas into words takes work. Jargon can also be translated. But unless the incentives are in place, this work won't be done.

(I set aside the question of people who deliberately obfuscate. This is simply compounding incompetence with fraud.)
