Another analogy is not to a child but to a part of the brain. Can a part of the human brain be intelligent? Are humans missing a part of their brain, such as through brain damage, intelligent? Such humans may not be as fully capable as humans with an uninjured brain, but (depending on the extent of the damage) we would still consider them intelligent and conscious. We may think of current AI's like that: as partially functional intelligences. But in a way they are more, because some of their functions exceed human capacity. So they are really something new: in some ways less than humans, in some ways more.
