"It Looks the Answers Up in a Database"
Captions available
The idea
A language model consults no database at answer time — no lookup exists, and both its unprecedented reach and its confident misses follow from prediction, not retrieval.
In practice
Systems that bolt on live document search do exist — a different machine wrapped around this one, and the wrapping needs its own audit.
Where people slip
The belief survives because retrieval is how every earlier answering machine worked.
