This seems fair enough to me. That ChatGPT currently struggles with certain types of maths problems points to reasonably fundamental shortcomings in what otherwise appears to have the beginnings of a general purpose reasoning engine (whether you consider it AGI or not), and I'm willing to bet extraordinarily clever minds are working hard on trying to address those shortcomings.
I don't think that trying to shoehorn LLM into being AGI is the right path. Maybe some are trying to achieve this, or are hoping for this... but IMO this is trying to fit a square peg into a round hole. It's definitely an element in the overall puzzle, I think we can all agree, though. Even so, rather than warping this hammer to also screw in a bolt, why not combine it with another tool more fit for the job?
