This AI Game Forgets Everything Behind You

You look at the ground. You look back up. The tree is gone. A lake is there instead. Nobody deleted it, the game simply forgot it. This is Oasis, an AI-generated Minecraft with no game engine inside, just a neural network guessing the next frame. Two broken brains explain why. In 1953 Henry Molaison lost the ability to remember today. In 1985 Clive Wearing's memory shrank to about thirty seconds. This is the story of a game that forgets, and the people who got there first: hippocampus, place cells, dreams, and the AI labs trying to give their worlds a memory.
