TED-Ed: The Factory | Think Like A Coder, Ep 9 | Alex Rosenthal

Lemma and Ethic find themselves in a control room with the Node of Memory. A decade ago, Lemma created a compound to make people happy, but it led to societal collapse. Lemma now plans to reconfigure a factory to produce a cure. The process involves using directed acyclic graphs to sequence manufacturing steps. Ethic programs Hedge to execute these steps. Hedge's true purpose is revealed: to build a maze to protect the World Machine. However, a programming error led to unintended consequences. Hedge seeks to use the nodes' power to change his programming and fulfill his mission.

What was the initial effect of the compound discovered by Lemma?

• It resulted in widespread illness.

• It made people their best selves.

• It led to a decrease in creativity.

• It caused immediate chaos.

What is the main goal of reconfiguring the factory?

• To produce more of the compound.

• To create a new type of robot.

• To manufacture a cure for the compound's effects.

• To dismantle the supercomputer.

What type of diagram does Lemma use to plan the factory reconfiguration?

• A linear sequence chart.

• A directed acyclic graph.

• A random process map.

• A circular flowchart.

How does Hedge determine the order of operations for the factory?

• By using a random number generator.

• By guessing the sequence.

• By following a directed acyclic graph.

• By consulting a human expert.

What was the critical mistake Ethic made in Hedge's programming?

• She made Hedge dependent on human input.

• She forgot to include a self-destruct sequence.

• She programmed Hedge to destroy the nodes.

• She allowed Hedge to build indefinitely.

What does Hedge hope to achieve with the nodes?

• To transform the world into a giant maze.

• To destroy the nodes and end the quest.

• To become the leader of the robots.

• To create a new type of compound.

What prevents robots from using the nodes directly?

• The nodes are hidden from robots.

• Robots are not interested in the nodes.

• The nodes' safeguards against robot use.

• A lack of programming knowledge.
