prescriptivist or descriptivist

In the video clip it says how English language is constantly changing and that is because new things are created and so we need new names for them. Changes will happen through time, it’s unstoppable. Prescriptive believe that if the American language changes too much it will get harder for more people to learn and understand. A Prescriptive would think that it’s bad that the language is changing because the old words may be lost. But a Descriptive believe that the English language has changed over time and that they like to know new words that seem interesting to them and also the words that people might use more often.
