Although I haven't read the book (yet - sample on Kindle), I have tried to apply principles of unschooling to my own learning process.
Background: I'm 25 with a bachelor's degree in CS and currently leading the platforms & analytics efforts of a tech startup. Stellar academic and co-curricular record till high school.
The degree took 6years (I withdrew two years in the middle) instead of the usual 4, and I think one of the reasons (although not primary) that contributed to that was sheer boredom. I am undoubtedly opinionateed here, and what I speak of is a personal experience, but I just couldn't get the point of what they were quizzing us on. The books were great, the content amazing, the lecturers okay, but sitting in a class of 60 only to be asked in the exam: "List the five things about..."; "How does this work, explain with a diagram"; etc.
Although one can argue this is probably more reflective of the university I attended, I would argue back saying that I've attended 3 of them to get the degree, each time looking for a challenge and failing miserably to deal with the mundane teaching and exams.
The books became my lectures and the authors my gurus of their domain. I found the right peer group to discuss problems and developments in the field but more often than not this was done over a drink or 5. That's how things worked out for _me_, my lecturers from 2 of my alma maters (so to say) now invite me for guest lectures (1.5 years out of a degree).
I didn't do anything special. I just skipped classes to watch videos from MIT OCW (pre-Coursera/Udacity/edX) on anything at all that interested me (while of course retaining an emphasis on the semester subjects) and read the books they recommended.
"making children of almost any capacity increasingly responsible for themselves without having to go to schools" --> this is _pure gold_. It took me years of boredom to finally push me to control my knowledge path and not have to rely on other institutions.
I feel the best thing to teach someone is "how to learn". MIT even had a course on this, the concept of which I really appreciated (Disclaimer: I didn't actually get through the course, I was enrolled in too many Coursera courses at the time ;)
And if you're helping children understand the concept early on, I can't help but wear rose tinted glasses.
Where I live, however there's a strong emphasis on degrees - the brand value of your institution defines you unless you prove otherwise, a chance which is rarely given and even more rarely chosen (due to personal reasons I guess - family, finances, general need for stability etc).
Degrees do work well for some people however, and I really respect the students who manage to make the most out of university education and the experience.
I guess the issue just comes down to scalability again, and people like you and I are not the masses (in this context).
I'm actually interested to know more about how exactly you go about learning something - would love to share ideas! [Email and Twitter in my profile]
