"Requiem For A Universe"

Poul Anderson sketches a future society effectively in the opening pages of this story. For reference, see here.

The narrator has spent a year helping with the construction of a Galactic Analyzer fifty astronomical units away from Earth;

he and his wife are holidaying in a primitive cottage on Kauai where they can be alone with sea, sand, flowers, sun and rainbows;

their phone, visual as well as auditory, can be set to respond only to important messages;

the narrator is a "linker" and his friend, David Rhys, is a "holothete";

both somehow interact with computers;

the narrator's wife is a school teacher;

most children are taught by computers although gifted children of well-off parents can instead have human teachers;

there is an Institute of Holothetes and also a Peace Command (the latter sounds familiar from other Anderson futures);

the Peace Command lends the Institute a sub-orbital rocket to take the narrator to France where his friend is catatonic.

A future full of information technology has been outlined and a human drama is about to begin.
