Yes, they didnt have sufficient monitoring or perfect sandboxes. That could happen again in the future with a more capable model.
Maybe a useful, if imperfect, analogy would be something like this: you lock a master lock-picker in a room with a mid-grade lock on the door, then tell him his wife has been kidnapped and only he can save her. Then act massively surprised when he disassembles the radiator to MacGuyver something with which to pick the lock.
Except they multiplied it by 10000, and didn't watch what was happening.
They did not even have bad sandboxes. They had incompetent sandboxes.
