I encountered quite interesting articles. I was aware of the risks involving in going to graduate school. At least no physics and mathematics professor I know recommended me to go to graduate school without talking about risks. Or probably no one really recommended me to go to grad school even though I never asked their advice either. They told us that you will see other people who just do any given tasks easily and make you think their brain are made of unknown materials etc. Also many books already informed me the hardships of graduate schools.
But it is quite nice to see some one writes so clearly about the danger of going to graduate in humanity. I am really not in humanity but many things are true in science as well.
He described horrific life in graduate school, but life can be much worse than he described. Any case, no matter what people write, I would go to graduate school in science or engineer even if I had a chance to change my life completely. Of course I would plan it better than before. Depending on the topic of studies, scientists may show no sympathy to difficulties of graduates from humanity disciplines. Some of the topics they study seem to be just an extension of hobby, but the real value of education is hard to measure.
