The problem, and I think the article indirectly points at that, is that the next generation to come along won't learn to think for themselves first. So they will on average end up on the 'B' track rather than that they will be able to develop their intelligence. I see this happening with the kids my kids hang out with. They don't want to understand anything because the AI can do that for them, or so they believe. They don't see that if you don't learn to think about smaller problems that the larger ones will be completely out of reach.
