Architecture

What is meant by terms like "mental architecture", "cognitive architecture", the "architecture of the AI", etc?

Robin Hanson: "I think our dispute in part comes down to an inclination toward architecture or content. That is, one view is that there's just a clever structure and if you have that basic structure, you have the right sort of architecture, and you set it up that way, then you don't need very much else, you just give it some sense organs, some access to the Internet or something, and then it can grow and build itself up because it has the right architecture for growth. Here we mean architecture for growth in particular, what architecture will let this thing grow well? [...] My opinion [...] is that it's largely about content. There are architectural insights. There are high-level things that you can do right or wrong, but they don't, in the end, add up to enough to make vast growth. What you need for vast growth is simply to have a big base. [...] I think that for minds, what matters is that it just has lots of good, powerful stuff in it, lots of things it knows, routines, strategies, and there isn't that much at the large architectural level."

is the difference between humans and chimpanzees mostly about architecture or content? there's also the question of humans now vs humans thousands of years ago, where it seems clear that the difference is culture/"content".
