Possibly depending how fast the individual can become viable, or able to live with the necessities given to it. Because there is a hole in between the time that it can live on it's own, and when it begins complex, human conscious thought. I can't find the link for the life of me right now because I forgot what it was called, and who conducted it, but an experiment was done to show that up to a certain age, we are intellectually similar to apes, in that we cannot conceive reason. After such point (I believe it was 2-3 years or something) this reasoning factor becomes apparent. So we could possibly have care for it until it can eat on it's own, which would render no effect on the outcome, because without our complex reasoning system, our perspective is null and void, and we usually do not remember this time in our life's. Or we can care for it for the starting years via robotics. Just kind of throwing out ways around what you have posted, which I must say is pretty damn interesting, thank you for that!

exactly the reason why i posted this link the reasoning we obtain is not because of an age we reach but more of exposure to outside influences some children can read and write by age 3-4 because the parents either accelerated the learning process or had a very nuturing caring atmosphere to raise the child in others that develop later in life that learn to read at the "normal" rate and age are the majority because they are not provided with the "ideal" atmosphere to develop at an increased rate

Well the problem that I have with that is that writing and speaking are not examples of actual intelligent reasoning, but merely exercises accomplished by focused repetition, reading can be done similarly, however is not a fully learned ability until the reader can actually correlate the contents of the text and understand what it's meaning is, rather than just know what the combination of symbols are suppose to sound like. The actual ability of understanding reasoning and being able to extrapolate meaning from data is something that the brain has to mature into, and is not born with it. This is what the test I mentioned uncovered, which then what I said beforehand can be inferred.

im sorry i got the original post confused with another comment about the reading and writing process XD
