The old model of education is a cathedral, and DIY is the bazaar, and each approach has its weaknesses.
MOOC is about as silly as "horseless carriage". The old model of education similar to a mathematical proof, with technical lemmas built up progressively until there is a macroscopically interesting result. That has a lot of value. Linear algebra is useful in so many fields, and learning it when you have the time, because you have to, gets it out of the way so you can progress to the fields you actually care about (machine learning, signal processing, physical sciences).
I think the new model will be graph-based and open like Wikipedia, but it will have to be aggressively curated for correctness, quality, and coherence. In 10 years, one should be able to take a query like "I want to be employable as a data scientist in 3 years" and turn that into a spanning tree of the relevant subgraph.
There'll also be a need for an offline/online hybrid approach like Meetup.com and dating sites-- some interaction offline, some in person-- and that part of it won't fulfill the dream of squashing geographic inequality. Perhaps education will be the first killer app for true "Metaverse" technology (but it won't be the last or biggest).
