wasn't in-context learning an emergent behavior a while ago (1-2 years)?

This is quite on brand for China. I think they are experts at reverse engineering and learning 'from context' rather than by formal consumption of foreign training material.

The fictional training data with a made up country and laws was a very interesting experiment design, I can imagine that's how they approach making business with other countries. Like an alien made up system they have to learn on the spot.
