Descriptivism is a vestige of pre-industrial society. Prescriptivism is a necessity of universal literacy. Language evolves over time, and one of the ways in which it evolves is how it evolves. Also, if you believe in linguistic descriptivism, you are also required to believe in a descriptivist system of weights and measures, or vice versa, or you're a hypocrite. Thank you for attending my TED talk, I am not taking questions.
