It seems there is a straw man leg of this thread arguing against a radical free-range osmotic thing and by proxy dismissing the whole principle of child-led learning.

I don't know if there is a realistic unschooling path for average parents or average kids, which isn't quite what the focus of the discussion ought to be here.

Can a gifted child have an interest in a specific area and be supported by their parents in pursuing information and training and support in that area? Why not multiple areas, why not within a guided scope of a bigger picture of life goals.

Will a typical teacher be as aware of a highly gifted kid's learning methodology and approach than that child combined with their parent? Experiences here says it's a coin toss or less.

As to the other side of the skill equation, will an expert in a particular field be inherently more competent at teaching that skill? No, pedagogical skills are different than field expertise. It might be better for someone to support their own learning through various sources than to waste time listening to the back of an instructor mumbling in broken English to a chalkboard.
