There are scalable bits of Education - courses, books, practice questions (look at leetcode), and lectures. I think that is why a lot of ed-tech fails. Information really does want to be free, and anything that can be broadcast is usually better free. Youtube has seen an influx of high quality content IMO.

There are also non-scalable parts - access to expert, prestige, and all the bits you've mentioned. I think that's probably where the future of ed-tech is going.
