There's a subset of people whose identity is grounded in the fact that they put in the hard work to learn things that most people are unable or unwilling to do. It's a badge of honor, and they resent anyone taking "shortcuts" to achieve their level of output. Kind of reminds me of lawyers who get bent out of shape when they lose a case to a pro se party. All those years of law school and studying for the bar exam, only to be bested by someone who got by with copying sample briefs and skimming Westlaw headnotes at a public library. :)
