This article in the Atlantic, while suuuuper technical and too long.. is FASCINATING, and absolutely worth reading, or at least skimming (what I did). I am very seriously now considering getting a landline again.
Basically, due to the PHYSICAL experience being so different, phoning feels less human and intimate. It's not just that we're lazy and anxiety-ridden. We just instinctively don't like it. The frequencies are off, and the shape of the device also affects our experience. What used to be an intimate experience (don't you remember with nostalgia the phone calls of the past?), is no longer. He makes an argument for why texting and emailing is actually a MORE intimate experience due to the way we are wired.
Totally fascinating.
