Software (and hardware) security is abysmal. This was increasingly obvious long before LLMs. Once companies stop gatekeeping, LLMs will be able to be used to help harden sites and we start making progress. In general LLMs are harmless. If somebody wants to hook an LLM up to a missile or whatever then they become dangerous, but the problem there isn't the LLM - it's the person using them to do awful things. In the same way a car used normally is harmless outside of freak accidents, yet a car can also be driven through a parade leaving mass death and destruction in its wake. But the problem there isn't the car.
