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?
