I kind of agree, but at the same time we can't be sure of what's going on behind the scenes. It seems that GPT-4 is a combination of several huge models with some logic to route the requests to the most apt models. Maybe an AGI would make more sense as a single, more cohese structure?
Also, the fact that it can't incorporate knowledge at the same time as it interacts with us kind of limits the idea of an AGI.
But regardless, it's absurdly impressive what it can do today.
