I did not say that the a machine intelligence mustn't share motivational complexity a la humans. I said that a SAI need not share such complexity. Those are two very different statements.
And to understand how/why a machine intelligence could arise without being substantially similar to a human intelligence and sharing similar motivations, well, I suggest you read the book or similar articles. In short, just because humans are the most sophisticated intelligences of which we yet know, it would be a very callous and unsubstantiated leap to believe that a machine intelligence is likely to share similar traits with humankind's intelligence. If this is unclear to you, I recommend you learn about how computer programs currently work, and how they're likely to improve to the point of becoming superintelligent.
By the way, there are many types of SAI, for example an SAI who's superintelligent portion relates to speed, or strategy, or a few other types.
