You are of course correct but let's not forget that humans get out of the woman's womb underdeveloped because a little more growth and the baby can't get out through the vagina. So it's a biological tradeoff.
Working on artificial organisms, we should be able to have them almost fully developed by the time we "free" or "unleash" them (or whatever other dramatic term we can think of).
At the very least we should have a number of basic components installed in this artificial brain, very similar to what humans are born with, so then the organism can navigate its reality by itself and optimize its place in it.
Whether we the humans are desired in that optimized reality is of course the really thorny question. To which I don't have an answer.
