Perhaps a business that makes money from educational content needs something that provides additional value (over and above what you'd get from a folder of videos), e.g.

A. Interactive features (scrimba.com)

B. Mentors (demandcurve.com)

C. Credentials (Udacity, Coursera)

D. Community/cohort

E. Convenient access to frequent updates (blinkist, shortform, getabstract)

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.

Is one that's doing Community/Cohort style learning by pairing Devs, PMs and Designers together to learn.
