1. Does AI weaken the Lucas critique? And a comment from Benjamin Manning.

2. “The economist view sees the comp sci position as a category error about knowledge is – not a claim about future capability levels but about the structure of the problem.”

3. Heritage Foundation is falling apart.

4. Kalshi Research, new arm of the company devoted to research on prediction markets.
