The only other source of information is the non-genomic environment - extra-nucleur DNA like mitochondria, and the womb (which is arguably already specified in the genome, unless mother nature has done a Ken Thompson http://cm.bell-labs.com/who/ken/trust.html at some point.)
That just gives you a newborn baby's brain, which is a pretty poor standard for displaying "human" intelligence. If we didn't get any smarter than that, we'd be pretty dumb by animal standards. To get to "human" intelligence, you have to be able to simulate a rich environment for the brain to learn from. You also have to model the growth of the brain and its response to stimulus -- the physics, chemistry, and biochemistry of the brain. DNA doesn't have to do that, because it runs on a platform with that functionality built-in (i.e., the real world.)
Yes, but it gives you the newborn baby's brain in toto, including its ability to grow up into a normal adult human. If you get to newborn's brain you are 99.9% of the way there from the AI side. By the time we get there, feeding it stimulus will be a relatively simple problem by comparison.
Not if the world is actually more complicated than a newborn baby's brain. Can we simulate a baby's interaction with its mother without simulating the mother's brain?
We have a world in hand. We're not trying to build a world simulation, we're trying to build intelligences. By the time we get this far, the infant will probably be embodied, and we can use real "mothers". Some speculate that a non-embodied being can never become intelligent.
Bear in mind we are talking about at least 20 years hence, in my mind.
