You have a bunch of stuff that isn't a mind at all. It's simple and it's not there yet. Then you have a bunch of stuff that is a fully complete mind capable of anything that any mind can do. There's also some special cases (you could have a very long program that hard codes how to deal with every possible input, situation or idea). AIs we create won't be special cases of that type which are a bad kind of design. This is similar to the computer design space, which has no half-computers.

I'm somewhat skeptical of this claim--I can design a mind that has the functions 0(n) (zero function), S(n) (successor function), and P(x0, x1,...xn) (projection function) but not primitive recursion, I can compute most but not all functions. So I'm skeptical of this "all or little" description of mind space and computer space.

However, I suspect it ultimately doesn't matter because your claims don't directly contradict my original point. If your categorization is correct and human beings are indeed universal knowledge creators, that doesn't preclude the possibility of us having cognitive biases (which it had better not do!). Nor does it contradict the larger point, which is that cognitive biases come from cognitive architecture, i.e. where one is located in mind design space.

Are you familiar with universality of computers? And how very simple computers can be universal? There's a lot of parallel issues.

If you're referring to Turing-completeness, then yes I am familiar with it.
