Scott Alexander presents a series of nested dialogues exploring the nature of understanding and meaning, from AI to humans to angels to God, questioning what true understanding entails.
Longer summary
This post is a philosophical exploration of the nature of understanding and meaning, presented through a series of nested dialogues. It starts with two children discussing an AI's understanding of water, moves to chemists debating the children's understanding, then to angels contemplating human understanding, and finally to God observing it all. Each level reveals a deeper layer of understanding, while simultaneously highlighting the limitations of the previous level. The post uses these dialogues to question what it truly means to understand something, and whether any level of understanding can be considered complete or meaningful.
