TED-Ed: The World Machine | Think Like A Coder, Ep 10 | Alex Rosenthal

Ethic recalls her past and the sacrifices made by her friends to stop Hedge, who plans to cover the world in a maze. Ethic devises a plan to use the crystal's power to stop Hedge, while the resistance stages a jailbreak. They use a depth-first search strategy to navigate the maze, marking dead ends with wire. Ethic ultimately corrects her past mistake, preventing catastrophe and restoring hope for the future.
