0:00:07.308,0:00:12.658 Hephaestus, god of technology, was hard at[br]work on his most ingenious invention yet. 0:00:12.658,0:00:15.946 He was creating a new defense [br]system for King Minos, 0:00:15.946,0:00:19.947 who wanted fewer intruders on his [br]island kingdom of Crete. 0:00:19.947,0:00:23.279 But mortal guards and ordinary [br]weapons wouldn’t suffice, 0:00:23.279,0:00:27.339 so the visionary god devised an [br]indomitable new defender. 0:00:27.339,0:00:29.025 In the fires of his forge, 0:00:29.025,0:00:33.535 Hephaestus cast his invention in [br]the shape of a giant man. 0:00:33.538,0:00:37.227 Made of gleaming bronze; endowed with [br]superhuman strength, 0:00:37.227,0:00:40.522 and powered by ichor, [br]the life fluid of the gods, 0:00:40.522,0:00:44.743 this automaton was unlike anything [br]Hephaestus had forged before. 0:00:44.743,0:00:49.433 The god named his creation Talos: [br]the first robot. 0:00:49.433,0:00:53.605 Three times a day, the bronze guardian [br]marched around the island's perimeter 0:00:53.605,0:00:55.389 searching for interlopers. 0:00:55.389,0:00:57.856 When he identified ships [br]approaching the coast, 0:00:57.856,0:01:00.763 he hurled massive boulders [br]into their path. 0:01:00.763,0:01:02.957 If any survivors made it ashore, 0:01:02.957,0:01:08.047 he would heat his metal body red-hot [br]and crush victims to his chest. 0:01:08.047,0:01:12.961 Talos was intended to fulfill his duties [br]day after day, with no variation. 0:01:12.961,0:01:15.040 But despite his robotic behavior, 0:01:15.040,0:01:19.200 he possessed an internal life his victims [br]could scarcely imagine. 0:01:19.200,0:01:20.124 And soon, 0:01:20.124,0:01:24.834 the behemoth would encounter a ship [br]of invaders that would test his mettle. 0:01:24.834,0:01:28.269 The bedraggled crew of Jason, Medea, [br]and the Argonauts 0:01:28.269,0:01:32.519 were returning from their hard-won quest [br]to retrieve the Golden Fleece. 0:01:32.519,0:01:34.972 Their adventure had taken [br]many dark turns, 0:01:34.972,0:01:38.969 and the weary sailors were desperate [br]to rest in a safe harbor. 0:01:38.969,0:01:42.420 They’d heard tales of Crete’s invulnerable[br]bronze colossus, 0:01:42.420,0:01:44.902 and made for a sheltered cove. 0:01:44.902,0:01:49.872 But before they could even drop anchor, [br]Talos spotted them. 0:01:49.872,0:01:53.668 While the Argonauts cowered at the [br]approach of the awesome automaton, 0:01:53.668,0:01:58.068 the sorceress Medea spotted a glinting [br]bolt on the robot’s ankle— 0:01:58.068,0:02:00.757 and devised a clever gambit. 0:02:00.757,0:02:02.989 Medea offered Talos a bargain: 0:02:02.989,0:02:05.593 she claimed that she could [br]make Talos immortal 0:02:05.593,0:02:08.206 in exchange for removing the bolt. 0:02:08.206,0:02:11.372 Medea's promise resonated deep [br]within his core. 0:02:11.372,0:02:13.869 Unaware of his own mechanical nature, 0:02:13.869,0:02:18.659 and human enough to long for [br]eternal life, Talos agreed. 0:02:18.659,0:02:22.971 While Medea muttered incantations, [br]Jason removed the bolt. 0:02:22.971,0:02:27.901 As Medea suspected, the bolt was a [br]weak point in Hephaestus’ design. 0:02:27.901,0:02:33.804 The ichor flowed out like molten lead, [br]draining Talos of his power source. 0:02:33.804,0:02:36.943 The robot collapsed with [br]a thunderous crash, 0:02:36.943,0:02:40.508 and the Argonauts were free [br]to travel home. 0:02:40.508,0:02:44.310 This story, first recorded in [br]roughly 700 BCE, 0:02:44.310,0:02:48.404 raises some familiar anxieties [br]about artificial intelligence— 0:02:48.404,0:02:52.399 and even provides an ancient [br]blueprint for science fiction. 0:02:52.399,0:02:56.739 But according to historians, ancient [br]robots were more than just myths. 0:02:56.739,0:02:58.583 By the 4th century BCE, 0:02:58.583,0:03:01.949 Greek engineers began making [br]actual automatons 0:03:01.949,0:03:05.946 including robotic servants and [br]flying models of birds. 0:03:05.946,0:03:08.748 None of these creations were [br]as famous as Talos, 0:03:08.748,0:03:12.509 who appeared on Greek coins, vase [br]paintings, public frescoes, 0:03:12.509,0:03:14.508 and in theatrical performances. 0:03:14.508,0:03:16.919 Even 2,500 years ago, 0:03:16.919,0:03:20.240 Greeks had already begun to investigate [br]the uncertain line 0:03:20.240,0:03:22.576 between human and machine. 0:03:22.576,0:03:25.810 And like many modern myths about [br]artificial intelligence, 0:03:25.810,0:03:31.736 Talos’ tale is as much about his robotic [br]heart as it is about his robotic brain. 0:03:31.736,0:03:36.226 Illustrating the demise of Talos on a [br]vase of the fifth century BCE, 0:03:36.226,0:03:39.536 one painter captured the dying [br]automaton’s despair 0:03:39.536,0:03:42.586 with a tear rolling down his bronze cheek.
