“Despite the rest of the group arguing with and (mostly) disagreeing with him for half the evening, my colleague stuck to his guns: it would be handy to have robots writing poetry for people. … But at the heart of my colleague’s provocative position was a utopian ideal: of a future in which technology was advanced enough to ‘do everything,’ even write poetry, so that no one needed to work. Yet this position wasn’t convincing either. His utopia sounded more than a little dull, and nobody wants to be bored out of their minds.” — Surekha Davies, Humans: A Monstrous History, 2025
Did you know?
There’s quite literally no place like utopia. In 1516, English humanist Sir Thomas More published a book titled Utopia, which compared social and economic conditions in Europe with those of an ideal society on an imaginary island located off the coast of the Americas. More wanted to imply that the perfect conditions on his fictional island could never really exist, so he called it “Utopia,” a name he created by combining the Greek words ou (“not, no”) and topos (“place”). The earliest generic use of utopia was for an imaginary and indefinitely remote place. The current use of utopia, referring to an ideal place or society, was inspired by More’s description of Utopia’s perfection.
