Something that deserves more attention is the fact that the textbook industry in the US runs like a cartel (as alluded to above, with professors requiring a particular book for which they get free copies, and the proceeds from which help to pay their salaries).
In Europe I preferred buying college textbooks to learn programming, because they were cheaper and better value than the commercial offerings, without the fancy graphic design covers and marketing outreach.
Saying that textbooks must die reminds me of the Nazis burning the books they considered un-German. Textbooks can be wonderful when they're really good, and no Kindle or anything will kill the joy of reading a book in paper. Of course, if one looks at marketing books, it's clear they're mostly junk and I would not mind if they were replaced by e-books at all. However, the same does not apply to math / physics books, which tend to require a lot of effort and time to be written, plus the illustrations, etc. This hard work needs to be paid for, and I am willing to pay for it just as long as it's more like $30 rather than the obscene $150.
To refrain from committing the same sin, let me explain that Rod's comment does not show why this blogposting by Godin is 'shallow' or 'vague' and uses the fallacy of 'poisoning the well', by connotating 'listenening to him' with 'acting as if he is a God', leaving no room for someone to say: well, this article is pretty decent, but on the whole I think Godin adds little worth reading.
I used to like reading Seth Godin. He makes some valid points. However, anyone with a functioning brain is capable of arriving at the same conclusions he does. He does not go into depth because there's no depth to go into. His posts are sweet and fluffy but have zero nutritious value. It's a bunch of truisms that add little to anyone's knowledge.
