"Khan Academy and its donors may preclude better products from coming along"

I just don't understand this. KA, Udacity, Coursera, Codecademy, MITx, teachontablo.com, this list goes on. I don't see how KA has done anything but prove the possibility of traction. When professors like Thrun and Norvig and investors like Paul Graham, Fred Wilson, and Peter Thiel are excited about the educational space, I believe the students will eventually win. It's no secret that many of the above have been inspired by Sal in one way or another.

The more products competing here, the better education will be. Yelling at Khan Academy because it's "the only thing that [exists]" feels...oddly misplaced.

I think it's a mistake for them to throw KA in the same category as traditional K-12 education in the first place. At least from my experience with it, people don't go on Kahn Academy to try to learn everything; it's more valuable when you're looking for knowledge about a specific subject, and you already have a reason for wanting to learn it.

The article's main criticism is that KA doesn't try to talk about all the possible uses of the subject matter. I'd rather they didn't, or at the very least kept it separate. Unless someone's being forced to sit down and watch educational videos, that doesn't add enough value to justify the time spent.

It may be that other competitors (including the ones you've mentioned) will try to fill the gap and take a more traditional education role. But saying something's bad just because it's not occupying the exact niche that the author wants it to? That's not a very useful criticism.

I feel like KA frees up some of the time constraints of traditional educators so that they can spend more time doing the motivation and the possible uses of a subject matter.

I'm no teacher but if I was I'd much rather spend my time getting kids excited about stuff and then point them to the resources they need to get going. I'd also have more time to answer questions so the kids wouldn't get as frustrated or stuck.

Replace "better products" with "the products I make" and it makes more sense.

Expect haters when you're doing something disruptive. The term 'disruptive' itself implies you're pissing someone off.

I'm sure Henry Ford had people who thought cars were a bad idea.

Carry on.

I don't mean to quibble, but you should really replace Henry Ford with Karl Benz. By the time Henry Ford got into the act, cars had already proven their usefulness. Ford's innovation was making cars cheap enough for the average person to afford.

Ford also wouldn't be happy about truly progressive, disruptive innovations like the rise of a strong labor movement.

What are you talking about? The labor movement in the US was stronger during Ford's lifetime than it has been since then, and Ford always had good relations with it.

But he also paid High wages.
