This was a wonderful TedTalk. I have just decided to change my major to Biology and become a pediatrician and this talk was extremely eye-opening and inspiring. Thank you, Dr. Chang, for the courage it took to give this talk in advocating for the rates of unhappiness in doctors, sharing your patients' stories with us, shedding light on the untapped potential in artificial intelligence in the medical field, and the fact that pediatrics is still a wonderful profession. God bless you.
