Artificial intelligence is changing how we interact with everything, from food to healthcare, travel and also religion. Experts say major global faiths are discussing their relationship with AI, and some are starting to incorporate this technology into their worship. Robot priests can recite prayers, perform funerals, and even comfort those experiencing a spiritual crisis. BBC Global Religion reporter Sofia Bettiza has taken a look at whether AI's relationship with religion is just a gimmick, or whether it can truly transform how people experience faith.

By the third century B.C., engineers in Hellenistic Alexandria, in Egypt, were building real mechanical robots and machines. And such science fictions and historical technologies were not unique to Greco-Roman culture. In my recent book "Gods and Robots," I explain that many ancient societies imagined and constructed automatons. Chinese chronicles tell of emperors fooled by realistic androids and describe artificial servants crafted in the second century by the female inventor Huang Yueying. Techno-marvels, such as flying war chariots and animated beings, also appear in Hindu epics. One of the most intriguing stories from India tells how robots once guarded Buddha's relics.

Princeton Univ, $29.95 (288p) ISBN 978-0-691-18351-0 The Greeks thought of everything, including sci-fi tropes such as androids and artificial intelligence, according to this lively study of mythology and technology. Stanford classicist Mayor (The Amazons) surveys myths from ancient Greece (with excursions to India and China) about bio-techne, life crafted by artifice. She finds a trove of them, including those of the bronze warrior-robot Talos, who patrolled Crete, hurling boulders at ships and roasting soldiers alive; statues by the legendary engineer Daedalus, so lifelike that they had to be tethered to stay put; and marvels by the blacksmith god Hephaestus, including automated rolling tripods that served Olympian feasts and talking robot servants to help at his forge. Taking a more organic approach, the witch Medea, after defeating Talos with sweet talk and trickery, invented herbal drugs to reverse aging. Mayor also looks at real-life automata in ancient Alexandria--mechanical beasts and people that moved, vocalized, and dispensed milk to bemused onlookers.
