It's not just about LLMs. AGI will be the result of many more iterations in this field of research, of which LLM is a part of. How quickly the iterations will happen is now being drastically revised down. If AGI is the space shuttle then LLMs are 19th century gliders. They may appear vastly difference but the knowledge that created both are connected in many ways. The space shuttle exist(ed) as a cumulation of knowledge acquired over many iterations of aviation/rocketry.

Edit: changed metaphor to a more commonly known one
