This reminds me a little of the transformation of radio. Traditional radio was based on one transmitter sending to thousands or millions of receivers. Now Pandora has turned that on its head, and each receiver can have hundreds of stations, each one waiting for the command to resume transmitting. Completely unthinkable back in the 60s or 70s or 80s or even 90s, now it’s ordinary. The only time in the last year that I’ve turned on a car radio was to tune into 1610 for whatever safety bulletin the highway department was broadcasting.
