It has been around 40 years since I read the story, so the details are a little vague. Best guess is it was published after Star Wars was released in 1977 and probably before 1980.
From my recollection, the author basically described virtual assistants like Siri/Alexa and something akin to the WWW.
The story started with the human asleep, and the computer woke him up, read him the important news, maybe some messages, and did some other stuff like maybe setting the thermostat and making coffee. Sort of a "day in the life with a virtual assistant."
