I'd like to recommend Ben Goertzel's book from 2006 Hidden Pattern, and particularly Chapter 2 "Kinds of Minds". (The book is also available at the author's site, but that may trigger SSL certificate warnings.)
We've come to understand that a future AGI may have non-anthropomorphic implementation and behavior, but this chapter situates possible minds in a variety of types of implementation and embodiment that I have not seen described elsewhere.
Specifically, p.17 compares
- High-resource minds (like AIXI) or modest-resource
and among modest-resource minds
- Embodied versus non, and within the "embodied" category: singly versus multiply versus flexibly embodied, and tool-dependent versus non
- Mindplexes versus fully unified minds
- Socially-dependent versus non
If there is other literature that enumerates and compares these and other kinds of minds, I'll be glad to know.
