Like to Fight? 1977 Soviet Cartoon Predicted Artificial Intelligence Weapons

The work of Soviet Director Anatoliy Petrov, Polygon is set on a remote island. A military crew is finishing preparations for a weapon testing range, cutting down palm trees, leveling sand, ejecting natives from their homes. As they work, a soldier notes the next closest island is five kilometers away, and the island is far removed from major shipping lanes and airways. The weapon in question then looms into view -- a gigantic tank. A Professor dressed in white also appears, and as he places a proud hand on the tank's armor plating, the scene flashes back to a younger version of the character, beaming as his son runs to him from the family house.
