Fair, and I will grant that a capable model (or human) could in theory break out of near anything.
My point is that this incident is not evidence of that. There is zero skill visible in the setup of the sandbox. Nobody messed up a critical detail, they didn’t even start to consider what the details were.
I doubt most people "blind to the possibility" would imagine that what we’re measuring against is the equivalent of benchmarking burglar skill based on how easily they can break through an unlocked door.
