A popular opinion on whether the iPhone makes the world a better place is that it doesn't. In fact, the iPhone makes us forget what the world looks like. with our heads always down focusing on gossip and texting your friends that you forget to look around you and enjoy the real world. another point is that while you're always looking down at your phone you are getting neck pains and bad eye sights and that might not seam like a big deal until you grow older and can hardly play with your grand kids because of how inflexible and fragile your neck is, and to the point where you could barley educate yourself because you cant see the notes on the board from your bad eye sight. last but not least, speaking of education, the iPhone is a huge distraction towards your goals of gaining knowledge. always on your phone unable to focus in your classes and making the classes, less prioritizing to them. over all no, the iPhone does not make the world a better place,
