The jargon can be functionally like bullshitting. It's preferentially aping language that's over everybody's heads in hopes of not being criticized. Whether that is a person's toxic habits (it's not, there's nobody in there) or an epiphenomenon of the design of the machine is less important: it's bullshitting if it's a social behavior there to manipulate people.
(jargon included where relevant, in hopes that people who know it will see it's the right word to use :) )
As such, LLMs can only bullshit.
