my impression is that by simulator and simulacra this post is not intending to claim that the thing it is simulating is realphysics but rather that it learns a general "textphysics engine", the model, which runs textphysics environments. it's essentially just a reframing of the prediction objective to describe deployment time - not a claim that the model actually learns a strong causal simplification of the full variety of real physics.
well, the fact that I don't have an answer ready is itself a significant component of an answer to my question, isn't it?
A friend on an alignment chat said something to the effect of:
And so I figured I'd come here and ask about it. This eval seems super shallow, only checking if the model is, on its own, trying to destroy the world. Seems rather shallow and uncreative - it barely touched on any of the jailbreaks or ways to pressure or trick the model into misbehaving.
