> They did it because people are expecting more out of their phones e.g. better cameras, better screen, battery life, TouchID, FaceID all whilst demanding the same thickness. Something has to give. First it was the 30-pin adapter, now it's headphone, next will be SIM.

Way to completely ignore the fact that there is room for a headphone jack in the iPhone 7 and the iPhone 8. It was not removed in order to make room for anything. See the video I posted above.
