You’re not the only one but I don’t really get this pedantry, and a lot of pedantry I do get. You’ll never get your average person to switch to the term LLM. Even for me, a techie person, it’s a goofy term.
Sometimes you just have to use terms that everyone already knows. I suspect we will have something that functions in every way like “AI” but technically isn’t for decades. Not saying that’s the current scenario, just looking ahead to what the improved versions of chat gpt will be like, and other future developments that probably cannot be predicted.
