What is Bradbury reminding us about as we finish reading Fahrenheit 451?

I was reminded of Ray Bradbury's Fahrenheit 451 a day or two ago while reading Ian Bogost on Apple's Airpods. Bogost examined Airpods' potential long term social consequences. "Human focus, already ambiguously cleft between world and screen," he suggests, "will become split again, even when maintaining eye contact." A little further on, he writes, "Everyone will exist in an ambiguous state between public engagement with a room or space and private retreat into devices or media."
