While you can say that LLMs have each of A, G and I, you may argue that AGI is A·G·I and what we see is A+G+I. It is each of those things in isolation, but there is more to intelligence. We try to address the missing part as agency and self-improvement. While we can put the bar arbitrarily high for homocentric reasons, we can also try to break down what layers of intelligence there are between Singularity Overlord (peak AGI) and Superintelligent Labrador On Acid (what we have now). Kind of like what complexity theorists do between P and NP.
