My biggest concern with child-led learning is if it does foster a certain self-absorption in children. I have homeschooling friends who are critcial of this kind of learning because they think it teaches the child that the world revolves around them and caters to them. They think rote learning and 6 hours of desk learning teaches children virtues.
And part of [the author's] response:
I believe children embrace learning and become enthusiastic, passion-driven learners only when they see how it connects to themselves .. how it helps them connect with their interests and their purpose. What is education for, if not this? And the rote learning, six hours at a desk a day .. what is that kind of education for? Not, I think, connecting you with your deepest passions and your purpose.
