Blaming "human ineptitude" is pessimistic. Sure, the fact that humans can't all manipulate computational machines directly and require layers of abstraction to effectively model problems can, technically, be called ineptitude, but really-- why be so down about it? That's the way things are and there's a lot of good that comes from software if you think about it for more than 30 seconds.
Human ineptitude is a part of our physical environment. We're just animals. Clever ones, but not perfect.
Furthermore it is a physical limitation for how much software you can write (and have it work) if you can get something that "mostly works" by building on top of yesterday's cruft then you do it, since the alternative is starting over from scratch and not being able to finish.
One of the more intriguing comments I've seen on HN. Care to elucidate?
