"Calls aren't ever really under our control anymore, they 'drop' intransitively. The signal can be lost, the device's battery can deplete, the caller can accidentally bump the touch screen and end the call, the phone's operating system can crash. The mobile hangup never signals itself as such, but remains shrouded in uncertainties," writes Ian Bogost, professor in the School of Literature, Media, and Communication, in his monthly guest column for The Atlantic.
