It's why we have reminants of New Greek and New Latin among
Doctors, Philosophers, Biologists, various Scientific
Disciplines, etc.
Chemistry seems to have somewhat of a valid reason for
precision... although its standards of nomenclature also show
shifts and changes due to fads of the time.
Jargon is fine if it carries extra information. Sometimes a
single word is better. But in my experience, there's not much
you couldn't teach to a young child that adults learn about in
_some_ form or another so that they can understand at least the
'gist' of the concept.
Yeah. Job security. If they don't understand us, we keep our
jobs longer.
