"These people are people who can study for a doctorate in liberal arts with confidence. Anyone else who does this will face great personal risks. They can't measure the full consequences of this choice because they don't understand the recruitment system of universities or don't want to listen to those who try to tell them the truth.

This is the choice I made after much deliberation.
