Interesting blog post and theory.<p>A core counter argument to their base premise is that learning effectively is done in person, as part of a social group, in a physical space dedicated to learning, with hands on practice. It certainly seems to be the core takeaways of Waldorf/Montessori/constructionist/etc. approaches.<p><i>> When our kids were in school and struggled with a class/teacher/subject, we would get them a tutor to come to our home in the evenings.</i><p>In other words, there's a reason they paid the tutor to come in person, and not tutor over Skype or the phone.<p>The author speaks of their intent being to open up access to education, and replace the "outdated tech" of physical schools and classrooms. I need to be convinced that successful execution of this plan (and its inevitable percolation into policy if it makes financial sense - which I have no doubt it does, for a VC to take interest in it) won't result in a two tiered system, with students from poorer families getting free, public education over video lessons, and students from wealthier family being able to attend private, more expensive, in person schooling.
