Epistemically Isolated AI: Talkie, an LM trained only on pre-1931 text

A Reddit post proposes EIAI (Epistemically Isolated Artificial Intelligence): deliberately restricting an AI system to a defined knowledge environment to study how its reasoning, judgment, and conclusions develop without selected information.
The working example is "Talkie: an LM from 1930," released in April 2026 by Nick Levine, David Duvenaud, and Alec Radford — a language model trained only on pre-1931 text, letting you chat with an AI whose knowledge ends before 1931. The author frames it as "temporally bounded epistemic reasoning" and a brilliant window into isolated reasoning over time, while acknowledging how hard isolating and verifying an LM's information boundary is in practice.
