text: The last way that this technology has no value, is that the way on how others feel, is none of your business. In paragrpah 5, is states, "For instance, you can probably tell how a friend is feeling simply by the look on her face." That statement is accurate, but no one really knows how anyone feels. Picture this, you have a best friend who you think is the most happiest person in the world, never in a million years would you think they're depressed. You download the app just for fun and use it on your friend to see how they really are feeling, you find out that the're really sad. You try to talk to them, but they get mad at you for being in their business and you come to the conclusion that you did do something wrong, because it was none of your business in the first place. How someone is feeling, is none of anyones concern and this app in an invasion of privacy.
