I don't think many people think we just need to scale. All of these things are giving us an idea of how to make AGI. So now we know how to get it to self improve. We can simulate a thinking process. When these things are combined it could get us closer.

If we can give it some kind of long term memory that it can use to retrieve and act upon that information and have some kind of common sense reasoning that that's very close to AGI.
