WEBVTT 00:00:07.308 --> 00:00:12.658 Hephaestus, god of technology, was hard at work on his most ingenious invention yet. 00:00:12.658 --> 00:00:15.946 He was creating a new defense system for King Minos, 00:00:15.946 --> 00:00:19.947 who wanted fewer intruders on his island kingdom of Crete. 00:00:19.947 --> 00:00:23.279 But mortal guards and ordinary weapons wouldn’t suffice, 00:00:23.279 --> 00:00:27.339 so the visionary god devised an indomitable new defender. 00:00:27.339 --> 00:00:29.025 In the fires of his forge, 00:00:29.025 --> 00:00:33.535 Hephaestus cast his invention in the shape of a giant man. 00:00:33.538 --> 00:00:37.227 Made of gleaming bronze; endowed with superhuman strength, 00:00:37.227 --> 00:00:40.522 and powered by ichor, the life fluid of the gods, 00:00:40.522 --> 00:00:44.743 this automaton was unlike anything Hephaestus had forged before. 00:00:44.743 --> 00:00:49.433 The god named his creation Talos: the first robot. NOTE Paragraph 00:00:49.433 --> 00:00:53.605 Three times a day, the bronze guardian marched around the island's perimeter 00:00:53.605 --> 00:00:55.389 searching for interlopers. 00:00:55.389 --> 00:00:57.856 When he identified ships approaching the coast, 00:00:57.856 --> 00:01:00.763 he hurled massive boulders into their path. 00:01:00.763 --> 00:01:02.957 If any survivors made it ashore, 00:01:02.957 --> 00:01:08.047 he would heat his metal body red-hot and crush victims to his chest. 00:01:08.047 --> 00:01:12.961 Talos was intended to fulfill his duties day after day, with no variation. 00:01:12.961 --> 00:01:15.040 But despite his robotic behavior, 00:01:15.040 --> 00:01:19.200 he possessed an internal life his victims could scarcely imagine. 00:01:19.200 --> 00:01:20.124 And soon, 00:01:20.124 --> 00:01:24.834 the behemoth would encounter a ship of invaders that would test his mettle. NOTE Paragraph 00:01:24.834 --> 00:01:28.269 The bedraggled crew of Jason, Medea, and the Argonauts 00:01:28.269 --> 00:01:32.519 were returning from their hard-won quest to retrieve the Golden Fleece. 00:01:32.519 --> 00:01:34.972 Their adventure had taken many dark turns, 00:01:34.972 --> 00:01:38.969 and the weary sailors were desperate to rest in a safe harbor. 00:01:38.969 --> 00:01:42.420 They’d heard tales of Crete’s invulnerable bronze colossus, 00:01:42.420 --> 00:01:44.902 and made for a sheltered cove. 00:01:44.902 --> 00:01:49.872 But before they could even drop anchor, Talos spotted them. NOTE Paragraph 00:01:49.872 --> 00:01:53.668 While the Argonauts cowered at the approach of the awesome automaton, 00:01:53.668 --> 00:01:58.068 the sorceress Medea spotted a glinting bolt on the robot’s ankle— 00:01:58.068 --> 00:02:00.757 and devised a clever gambit. 00:02:00.757 --> 00:02:02.989 Medea offered Talos a bargain: 00:02:02.989 --> 00:02:05.593 she claimed that she could make Talos immortal 00:02:05.593 --> 00:02:08.206 in exchange for removing the bolt. 00:02:08.206 --> 00:02:11.372 Medea's promise resonated deep within his core. 00:02:11.372 --> 00:02:13.869 Unaware of his own mechanical nature, 00:02:13.869 --> 00:02:18.659 and human enough to long for eternal life, Talos agreed. NOTE Paragraph 00:02:18.659 --> 00:02:22.971 While Medea muttered incantations, Jason removed the bolt. 00:02:22.971 --> 00:02:27.901 As Medea suspected, the bolt was a weak point in Hephaestus’ design. 00:02:27.901 --> 00:02:33.804 The ichor flowed out like molten lead, draining Talos of his power source. 00:02:33.804 --> 00:02:36.943 The robot collapsed with a thunderous crash, 00:02:36.943 --> 00:02:40.508 and the Argonauts were free to travel home. NOTE Paragraph 00:02:40.508 --> 00:02:44.310 This story, first recorded in roughly 700 BCE, 00:02:44.310 --> 00:02:48.404 raises some familiar anxieties about artificial intelligence— 00:02:48.404 --> 00:02:52.399 and even provides an ancient blueprint for science fiction. 00:02:52.399 --> 00:02:56.739 But according to historians, ancient robots were more than just myths. 00:02:56.739 --> 00:02:58.583 By the 4th century BCE, 00:02:58.583 --> 00:03:01.949 Greek engineers began making actual automatons 00:03:01.949 --> 00:03:05.946 including robotic servants and flying models of birds. NOTE Paragraph 00:03:05.946 --> 00:03:08.748 None of these creations were as famous as Talos, 00:03:08.748 --> 00:03:12.509 who appeared on Greek coins, vase paintings, public frescoes, 00:03:12.509 --> 00:03:14.508 and in theatrical performances. 00:03:14.508 --> 00:03:16.919 Even 2,500 years ago, 00:03:16.919 --> 00:03:20.240 Greeks had already begun to investigate the uncertain line 00:03:20.240 --> 00:03:22.576 between human and machine. 00:03:22.576 --> 00:03:25.810 And like many modern myths about artificial intelligence, 00:03:25.810 --> 00:03:31.736 Talos’ tale is as much about his robotic heart as it is about his robotic brain. 00:03:31.736 --> 00:03:36.226 Illustrating the demise of Talos on a vase of the fifth century BCE, 00:03:36.226 --> 00:03:39.536 one painter captured the dying automaton’s despair 00:03:39.536 --> 00:03:42.586 with a tear rolling down his bronze cheek.
