Jargon is the little-death

Somewhere in France someone is getting really excited about learning jargon.

Definitely are.

In a way it makes sense because the industry loves its acronyms and you'll be using them.

On the other hand, I have the ability to search. I'm an IT professional, I will have a computer. Let me let the computer do the lookup. Its the old "you won't have a calculator with you all the time" argument that was dated when my teachers told it to me.

Absolutely! One of the difficulties that I have with my intro courses is working out when to introduce the vocabulary correctly, because it is important to be able to engage with the industry and the literature, but it adds a lot of noise to learning the underlying concepts and some assessments end up losing sight of the concept and go straight to recalling the vocab.

Knowing the terms can help you self-learn, but a textbook glossary could do the same thing.

Yeah, I may be wrong but I think it usually comes down to a very specific kind of precision needed. It's not meant to be hostile, I think, but meant to provide a domain-specific explanation clearly to those who need to interpret it in a specific way. In law, specific jargon infers very specific behaviour, so it's meant to be precise in its own way (not a law major, can't say for sure), but it can seem completely meaningless if you aren't prepped for it.

Same thing in other fields. I had a professor who was very pedantic about {braces} vs [brackets] vs (parentheses), and it seemed totally unnecessary to be so corrective in discussions, but when explaining where things went wrong with a student's work it was vital to be able to quickly differentiate them in their work so they could review the right areas or understand things faster during a lecture later down the line.

But that noise takes longer to teach through, so if it is important, it needs it's own time to learn, and it will make it inaccessible to anyone who didn't get that time to learn and digest it.
