Though this is only relative to current techniques for teaching programming, and we shouldn't assume we know all there is to know about how to teach programming. There's reasons to think there's a lot of scope for improvement. For a very general reason: that we don't really know that much about how our brains and thinking work. Once we do we are likely to be much better at identifying precisely why some people are poor at certain tasks, and at knowing how to train people to improve their skills at those tasks.
