I think the idea of the OLPC was just ahead of its time. A good live teacher will likely always be able to provide higher quality education, but at some point recorded lectures and adaptive learning software will be adequate and more cost effective than the average live teacher who can only teach a few dozen students at a time. If the alternative is no or low quality education then certainly that would be preferable.
