Spike, I appreciate your enthusiasm for educating your son and applaud it.
(So please don't take my comments as criticism).

The Sal Khan Academy is one extreme.
Looking at education from the opposite extreme, I have read articles
worrying about smartphones causing the dumbing-down of the population.
With a smartphone, nobody needs to remember or know much at all.
Google gives you any info you need. Apps do calculating for you, give
directions, organise schedules, buy stuff, etc.
That's why the younger generation are addicted to gossiping on their
smartphones.
There's not much else left for them to do.
