I agree, take a thousand brain theory book for instance, the author argues that artificial intelligence will never be a threat to humanity, since it won't have motives like we do. Primal motives are hardwired in our brain, they are actually shortcut to our muscles that our intelligence possesses no control over. On the other hand, the neocortext, the part of the brain that is actually intelligent, doesn't exhibit such motives... Creating intelligence that mimics ours is just bad design, artificial intelligence will probably look a lot different than ours.
