If a professor learns from multiple books, generalizes from them and then shares his knowledge he is providing a valuable service. Versus someone who makes a recording of the professor's lectures and resells them to undercut the professor--that guy is not providing a valuable service. |

Teaching isn't a race to the bottom. You don't undercut teaching by giving more lessons, just like you don't slight the hospital by performing CPR.
