This is some real inspiration porn. The kid sounds amazing, and it's tragic that he died so young. I have family that practices unschooling, and in their case, that means fundamentalist indoctrination, no math, no history, near illiteracy, no saleable skills or motivation to get a job or do anything independently. And I just know that they're going to send this to my mom as evidence that they're doing the right thing…
For the truly remarkable (and the subject here seems to fit that), sticking them in any factory-like school setting is a waste. Un-schooling the majority of children would be an interesting social experiment that I'd rather see in a different country first.
The brightest candles burn out the fastest, wasn't that they saying, roughly?
