A reader offers this comment about the education marketplace:

Better and cheaper aren’t even issues in the disruptive Educational marketing game. Only profit matters. Especially if you capture regulatory control, you can degrade quality to reduce cost, then mandate public funding to maximize profits. There’s no public sector, and no free market, to stop you.

I’ll quote again from Farrell:
“Christensen’s theory of innovation showed how “true revolutions occur, creating new markets and wreaking havoc within industries. Think: the PC, the MP3, the transistor radio.”

The wheel is still spinning on applications of internet and satellite “technology” in education. I’m a visionary and innovator myself, but in our classrooms, profit seekers are trying to freeze out wondrous real advances for their own advantage. Don’t confuse innovation with mean-minded little schemes to curtail and monetize other people’s inventions. The emperor is naked, and has no actual innovations to offer.

If you want to think more deeply than opportunistic market manipulation, here’s Anil Dash’s magnificent rumination on the internet, The Web We Lost:

He also understands the wheels are still spinning, and proposes ways to bring the internet back into the commons, where (like public education) it belongs.
