If you're interested in such things, then start layering on epigenetics. The "I" is a product not just of genes, but of your environment as you developed. I was just reading about bees' "royal jelly" recently, and how genetically identical larvae can become a queen or a worker based on their exposure to it.

So the program is not just the zeroes and ones, so to speak, but also more nebulous real-time activity, passed on through time. Like a wave on the ocean.
