> A machine can help you accumulate facts, but it can't educate you (in the sense that I'm talking about.) We are clearly on the precipice of having machines that can model the human mind and help us figure out where we are blocked on learning a topic. > you can't measure "mastery" in any meaningful sense This seems a ridiculous assertion to me. Bloom's "Learning for Mastery" paper explains what he means by mastery, which is quantified in tests. I don't see how you can reconcile your belief that "We've got these machines that are [about to be] able to do anything a human can do" with your belief that "A machine can help you accumulate facts, but it can't educate you". I never thought or wrote that "the purpose of education is to secure a place in the economic hierarchy". I specifically wrote that we can use computer tutors to augment human tutors. The best we can do with human tutors is 1:1 tutoring. With computer tutors, we will have a lot more capacity available. I meet many people who have been conditioned to think that they are "not good at math" or that they "don't have a brain for math or science" or that they are not "artistic" enough to paint or play an instrument. I think, in most cases, this is simply wrong and a rationalization or conditioning. Most people just did not have enough personal tutoring to get them past whatever obstacle was next in the way to learning. Computer tutoring is going to unlock potential, not just for economic success, but to give humans more options to explore whatever they want. Computer tutors will be able to model the human brain and, like human tutors, know how to rephrase something to help a student understand. When I was a boy learning algebra and calculus, I had to contend with my classmates for time from the teacher to get explanations on certain questions. When I wanted to learn an instrument as a boy, there was simply not enough tutors available. Computer tutors will greatly amplify teaching capacity.
