Debate: new model abilities emerged via generalization, not a shared RL env

A widely circulated exchange: after a Japanese user marveled at a model's video output resembling Fable, LinusMixson argued that this ability emerged all at once across every model family because of generalization — not because someone sold a "code painting" RL environment to all the labs.

It's a pointed take in the ongoing debate about emergent capability mechanisms, pushing back against the theory that labs bought the same RL training environment from a common vendor.
