ONE of the best-selling novels of the 19th century was a work of what we’d now call speculative fiction: Edward Bellamy’s “Looking Backward: 2000-1887”. Bellamy was one of the first prominent figures to recognise that rapid technological progress had become an enduring feature of modern life — and he imagined that this progress would vastly improve human happiness.

In one scene, his protagonist, who has somehow been transported from the 1880s to 2000, is asked if he would like to hear some music; to his astonishment his hostess uses what we would now call a speakerphone to let him listen to a live orchestral performance, one of four then in progress. And he suggests that having such easy access to entertainment would represent “the limit of human felicity”.

Well, over the past few days I’ve watched several shows on my smart TV — I haven’t made up my mind yet about the new season of “Westworld” — and also watched several live musical performances. And let me say, I find access to streamed entertainment a major source of enjoyment. But the limit of felicity? Not so much.
