Ramin Bahrani (who may not be objective, as he has directed a film adaptation of the Bradbury book): “In the novel, he imagined a world where people are entertained day and night by staring at giant wall screens in their homes. They interact with their ‘friends’ through these screens, listening to them via ‘Seashells’ – Bradbury’s version of Apple’s wireless AirPods – inserted in their ears.”
