Exactly. Very few of these people will actually listen to the first lecture, and very few of those people will put in the work to complete the course and master the material.
Damn. AI 3rd ed on amazon is $115. Assume the authors get $50 so Norvig gets $25. He may have just banked $2.5MM.
No disrespect meant -- it's awesome to see Stanford experimenting with education like this. But still... wow.
Edit: reminds me of the $24MM house Stewart -- of Stewart's calculus -- built with earnings from his calc texts [1]. I'm not hating on educators being paid well, but particularly stewart seems a little... unseemly, particularly in light of the constant churn of new editions. Has calculus or calculus pedagogy seriously changed in the last 10 years in a way that requires a stream of new calc book editions?

Speaking as a math prof: No. No. NO. It is a ripoff of our students, pure and simple.
When teaching calculus at a previous job we used the eighth edition of this calculus book by Varberg et al., and the statement of Taylor's theorem (one of the major theorems of calculus) was wrong. You figure, eight editions, you could get it right. But evidently I was naive.
However, a couple of universities I have taught at have explicitly told publishers that if they go to a new edition, and stop selling the old one, then the department will move to a different book entirely. I've finally moved up to a tenure track job; I'm going to enjoy this game of hardball :)
The best introduction to Calculus is classic "Calculus Made Easy" by Silvanus P. Thompson. It is in public domain, is a de-facto standard and is praised by many working scientists (Antony Zee, for example).
It gives you a working knowledge to get going with almost any practical problem you may encounter that needs to be approached with mahtematical analysis.
I would say that Spivak books are more about learning the culture of working mathematicians, and while with its merits one must be careful with commitment of investing her personal time to it.
Also, here is a great page to learn about good (and usually public) books for different branches of mathematics and physics by a Nobel-winning theoretical physicist G. t'Hooft

Have not seen any of these public domain books yet, but I hope they catch on!
I don't have a favorite yet; Thomas was good, I expect to also like Stewart (which I am using for this first time this fall). As is typical, the math department as a whole chooses which book to use.
I'm not familiar with the `aristocratic' books (Spivak, Apostol), but I have heard they are excellent. I don't need to learn calculus anymore :) -- but I will check them out if I ever teach an honors class.
In America people shouldn't be able to get rich selling education? I guess we're ok with movie stars, athletes, and rock stars making crazy money but it just doesn't seem right that educators can make their fortune? Maybe we should encourage them to move into finance if they really want to make lots of money?
This is your conclusion from reading about a class at the top university in the US offering completely free courses from renowned experts to anyone in the world who wishes to sign up? They are greedy bastards getting rich? That is really what you conclude from this story. Amazing.
In fairness to Stewart, his calculus book is actually pretty awesome. I had a class that used another book, written by one of the professors, and went out and bought another copy of Stewart's book because I could actually follow it. He does a very good job of explaining something that can be difficult. Trying to learn from a poorly constructed book really increased my respect for the quality of Stewart's explanations. There is a very good reason that his book is so well used.
Considering I can only get about sixty percent conversion to making a bingo card if I catch you in the same session as signup, and that making a bingo card is vastly easier than programming, I think you're overestimating by probably 100x or so.
It should be noted that outside the US, the international 3rd edition of the book (supposedly containing some undisclosed differences) can be had much cheaper. I bought a new copy from a seller in Malaysia back in April for about $50 USD.
