The argument you are using privileges one aspect (greater access) above the whole (quality, depth of understanding, mastery etc).
The author is arguing (rightly) that the current system is a pass for educational 'meh - good enough' when we should and must try to get HIGH quality education to everyone.
A lot of proponents of MOOCs, argue that it is an improvement over what we have - that more people are going to be able to learn and be exposed.
This is fundamentally flawed as it as an over-optimistic assesment of the results.
MOOCs will have 2 outcomes
1) They will be great for auto didacts, and they will be the leading edge of subscribers and proponents.
2) They will become certification factories which prove that you can solve X test material (not subject matter) at the end of it.
Would you be OK with Math being considered the same as mental parlor tricks? Differentiation being reduced to knowing steps to carry out? Or History being reduced to rote learning?
I suspect that you will say NO, as would most people understand education to be the same as Knowing and understanding something, not being able to remember it like you would a song stuck in your head.
MOOCs can only go so far - and this is their weakness and the issue educators are trying to point out.
Having seen the philosophy of "good enough" applied to an entire country first hand, I assure you the outcome is misery. Cynical students who realize that getting an answer and learning are no longer happening, and all that matters is acing that test.
A good quality education is expensive. But the side effects of having an educated population (as opposed to literate and trained) is immense.
Half assing this is having engineers, who couldn't do R and D if his life depended on it, and instead he can create value by picking up a phone and saying "Hi this is Sammy speaking".
