1 00:00:07,308 --> 00:00:12,658 Hephaestus, god of technology, was hard at work on his most ingenious invention yet. 2 00:00:12,658 --> 00:00:15,946 He was creating a new defense system for King Minos, 3 00:00:15,946 --> 00:00:19,947 who wanted fewer intruders on his island kingdom of Crete. 4 00:00:19,947 --> 00:00:23,279 But mortal guards and ordinary weapons wouldn’t suffice, 5 00:00:23,279 --> 00:00:27,339 so the visionary god devised an indomitable new defender. 6 00:00:27,339 --> 00:00:29,025 In the fires of his forge, 7 00:00:29,025 --> 00:00:33,535 Hephaestus cast his invention in the shape of a giant man. 8 00:00:33,538 --> 00:00:37,227 Made of gleaming bronze; endowed with superhuman strength, 9 00:00:37,227 --> 00:00:40,522 and powered by ichor, the life fluid of the gods, 10 00:00:40,522 --> 00:00:44,743 this automaton was unlike anything Hephaestus had forged before. 11 00:00:44,743 --> 00:00:49,433 The god named his creation Talos: the first robot. 12 00:00:49,433 --> 00:00:53,605 Three times a day, the bronze guardian marched around the island's perimeter 13 00:00:53,605 --> 00:00:55,389 searching for interlopers. 14 00:00:55,389 --> 00:00:57,856 When he identified ships approaching the coast, 15 00:00:57,856 --> 00:01:00,763 he hurled massive boulders into their path. 16 00:01:00,763 --> 00:01:02,957 If any survivors made it ashore, 17 00:01:02,957 --> 00:01:08,047 he would heat his metal body red-hot and crush victims to his chest. 18 00:01:08,047 --> 00:01:12,961 Talos was intended to fulfill his duties day after day, with no variation. 19 00:01:12,961 --> 00:01:15,040 But despite his robotic behavior, 20 00:01:15,040 --> 00:01:19,200 he possessed an internal life his victims could scarcely imagine. 21 00:01:19,200 --> 00:01:20,124 And soon, 22 00:01:20,124 --> 00:01:24,834 the behemoth would encounter a ship of invaders that would test his mettle. 23 00:01:24,834 --> 00:01:28,269 The bedraggled crew of Jason, Medea, and the Argonauts 24 00:01:28,269 --> 00:01:32,519 were returning from their hard-won quest to retrieve the Golden Fleece. 25 00:01:32,519 --> 00:01:34,972 Their adventure had taken many dark turns, 26 00:01:34,972 --> 00:01:38,969 and the weary sailors were desperate to rest in a safe harbor. 27 00:01:38,969 --> 00:01:42,420 They’d heard tales of Crete’s invulnerable bronze colossus, 28 00:01:42,420 --> 00:01:44,902 and made for a sheltered cove. 29 00:01:44,902 --> 00:01:49,872 But before they could even drop anchor, Talos spotted them. 30 00:01:49,872 --> 00:01:53,668 While the Argonauts cowered at the approach of the awesome automaton, 31 00:01:53,668 --> 00:01:58,068 the sorceress Medea spotted a glinting bolt on the robot’s ankle— 32 00:01:58,068 --> 00:02:00,757 and devised a clever gambit. 33 00:02:00,757 --> 00:02:02,989 Medea offered Talos a bargain: 34 00:02:02,989 --> 00:02:05,593 she claimed that she could make Talos immortal 35 00:02:05,593 --> 00:02:08,206 in exchange for removing the bolt. 36 00:02:08,206 --> 00:02:11,372 Medea's promise resonated deep within his core. 37 00:02:11,372 --> 00:02:13,869 Unaware of his own mechanical nature, 38 00:02:13,869 --> 00:02:18,659 and human enough to long for eternal life, Talos agreed. 39 00:02:18,659 --> 00:02:22,971 While Medea muttered incantations, Jason removed the bolt. 40 00:02:22,971 --> 00:02:27,901 As Medea suspected, the bolt was a weak point in Hephaestus’ design. 41 00:02:27,901 --> 00:02:33,804 The ichor flowed out like molten lead, draining Talos of his power source. 42 00:02:33,804 --> 00:02:36,943 The robot collapsed with a thunderous crash, 43 00:02:36,943 --> 00:02:40,508 and the Argonauts were free to travel home. 44 00:02:40,508 --> 00:02:44,310 This story, first recorded in roughly 700 BCE, 45 00:02:44,310 --> 00:02:48,404 raises some familiar anxieties about artificial intelligence— 46 00:02:48,404 --> 00:02:52,399 and even provides an ancient blueprint for science fiction. 47 00:02:52,399 --> 00:02:56,739 But according to historians, ancient robots were more than just myths. 48 00:02:56,739 --> 00:02:58,583 By the 4th century BCE, 49 00:02:58,583 --> 00:03:01,949 Greek engineers began making actual automatons 50 00:03:01,949 --> 00:03:05,946 including robotic servants and flying models of birds. 51 00:03:05,946 --> 00:03:08,748 None of these creations were as famous as Talos, 52 00:03:08,748 --> 00:03:12,509 who appeared on Greek coins, vase paintings, public frescoes, 53 00:03:12,509 --> 00:03:14,508 and in theatrical performances. 54 00:03:14,508 --> 00:03:16,919 Even 2,500 years ago, 55 00:03:16,919 --> 00:03:20,240 Greeks had already begun to investigate the uncertain line 56 00:03:20,240 --> 00:03:22,576 between human and machine. 57 00:03:22,576 --> 00:03:25,810 And like many modern myths about artificial intelligence, 58 00:03:25,810 --> 00:03:31,736 Talos’ tale is as much about his robotic heart as it is about his robotic brain. 59 00:03:31,736 --> 00:03:36,226 Illustrating the demise of Talos on a vase of the fifth century BCE, 60 00:03:36,226 --> 00:03:39,536 one painter captured the dying automaton’s despair 61 00:03:39,536 --> 00:03:42,586 with a tear rolling down his bronze cheek.
