Neil deGrasse Tyson has a very valid argument behind why he doesn’t use a phone case. A thin phone does decrease your risk of dropping it, It doesn’t mean he won’t ever drop it. I don’t drop my iPhone X all that often either, but that once in a while I do I’m pretty glad my phone’s case is around it to keep me from having to replace my very expensive screen.
