As used in discussions of human intelligence and psychometrics, g has been around for about a century now. I don’t believe I’ve seen a single instance of someone in the field not understand the usage. In this case, g or ”g factor” seems to be a very helpful term. When I first became interested in the study of intelligence, I wasn’t at all confused by it, and I knew of the physics use of the same letter. (And I never confused lowercase g as used in physics with it as used in function theory (for another function so you say things like f(g(x)) = g(f(x)).)

Actually, coming up with new letters, etc. each time is okay (think of Cantor using the Hebrew alphabet in his work), but I don’t see any big confusion here. Even AGI seems to be a decent distinction, though one could argue AI == AGI. (That’s what’s under discussion by those making the distinction, so I wouldn’t rule it out as meaningless if I were to think AGI is nothing more than AI. Folks inventing the term were not aiming to obfuscate to my knowledge.)
