How does "get okay at software engineering" entail that it is able to strategize at the level your scenario requires? Finding an OpenSSL exploit already seems like a big leap, but one that okay maybe I can concede is plausible. But then on top of that engineering and executing a series of events leading to the extinction of humanity? That's like an entirely different skillset, requiring plasticity, creativity, foresight, etc. Do we have any evidence that a big neural network is capable of this kind of behavior (and moreover capable of giving itself this behavior)? Especially when it's built for single-purpose uses (like an LLM)?
