I find it amusing how this question even needs to be asked. LLMs are well-established at this point. There's a wide range of experience with them (and their results). A better question to ask then is: "based on my first-hand experience, have I seen anything, anything at all, that would organically (not influenced) make me think/feel this technology can or will evolve into something capable of killing off humanity?"

On a purely technical basis, the most common, honest answer is "no." There are no inherent properties of LLMs that would make them independently turn computers into death machines. That's all humans, no matter how you dress it up.

There is, however, the hubris (human) problem. The rhetorical, experimental, and financial irresponsibility around this tech's roll out is far greater a threat to humanity than the actual technology itself.

And frankly that's a shame because LLMs are a phenomenal tool. But the Hollywood shit has cooked people's brains to the point of absurdity.
