There exists a button that, when pressed, makes every human’s IQ become 200. However, humans will experience no emotions whatsoever, including empathy, love or attachment, joy, anger, fear, sadness, disgust, pride, shame, jealousy, spite, hatred, guilt, regret, frustration, irritation, resentment, envy, contempt, grief and all other possible emotional states. Humans still have preferences, can plan and act, can understand what others believe and want, but cannot feel anything about it. This change is global and cannot be reversed, and every human onward will be born this way.
