How is text-based memorization going to substitute for learning? The two are not the same. Perhaps this is more applicable to robotics than a text generator, but I also doubt an LLM could learn text-based skills like programming or math if it had not been pre-trained on them via SGD & RL, and had to instead rely on some poor-man's-learning context-based recall instead. What else can't it learn? How is the LLM intern, the "drop-in replacement remote worker" going to do on day #2?
Instead of pretending that an LLM can be human-level, or super-human, or become generalist, why not just admit that this is not the final form of AI. An LLM is not an animal/human-like intelligence, it is something different - a language model, with it's own strengths and weaknesses.
Despite all the AGI hype, an LLM seems to have more in common with a pre-trained single-purpose system like AlphaGo than a brain, but with the rubric/reward-based policy function baked into the weights.
In another 10-20 years some new idea, hopefully more brain-like, will have superseded LLMs and they will indeed be labelled as "LLMs" as the AI/AGI label becomes attached to the new more brain-like creative intelligence. Perhaps it'll be sooner than 10-20 years, but I doubt it given the current 10-year fixation with LLMs which doesn't appear to be slowing down anytime soon. Perhaps Sutskever is working on something a bit different?
