Things start to get a bit more challenging for new entrants to the field. It’s true that this language can initially be a blocker. In fact it can be super frustrating when talking to an expert and they say a bunch of things you don’t understand. I’ve been in plenty of situations in my career where somebody has said something in a casual, confident tone and I’ve feigned understanding, only to go and look up the term later.
In writing there are usually style rules when an acronym or technical term is expanded or defined in its first use for readers. We should make a habit of deliberately doing this, as well as using links to a shared definition in a wiki etc). In speech, this should also be done.
