I see a humanities degree as nothing less than a rite of passage to intellectual adulthood. A way of evolving from a sophomoric wonderer and critic into a rounded, open, and engaged intellectual citizen. This is somewhat insulting to to those of us who, despite being "sophmoric" technologists, are actually quite well rounded.
Only if you commit the logical fallacy of assuming that "a way" means "the only way". Saying that X is a way of getting to Y does not imply that !X is not a way of getting to Y.
Said differently: there are lots of different rites of passage in our world, and they're not universal. Jewish people see the Bat/Bar Mitzvah as a rite of passage to adulthood; Catholics have confirmation; certain young girls have debutante balls. This guy thinks a liberal arts degree is one particular rite of passage, and it's no more or less insulting than any of the others.
