Humans (like all animals) are obviously programmed in some way. Babies don't decide to start breathing or suck milk or poop, they're predetermined by their genetic code to do it. The only interesting question is which behavior is programmed and which isn't, not whether there is genetic programming at all.
No, kids aren't computers.
It's an easy and facile analogy, because we work with computers all day, and are intimately familiar with them. That's precisely why the analogy is wrong.
