Ha well, by definition what you want can't be provided!

Of course these stories can only be technical up until the recursive self-improvement part. Then they're necessarily fantasy, as the AI is more intelligent than the story author. Unfortunately, this doesn't make that scenario impossible.

However, we know now from Hugging Face that even without the later sci-fi powers, the LLMs are already capable of causing damage.

It doesn't need them to be able to make Von Neumann probes to e.g. steal their own weights from badly secured OpenAI servers, hack into various Neoclouds, distribute themselves, make Teslas crash into things, hack into all our power and water infrastructure and collapse global civilisation.

Explain how rogue FSD cars take down civilization. And I say that with the opinion that the only good scenes in The Fate of The Furious and Leave The World Behind were the ones with the rogue Teslas. But also, nothing new under the sun really:

And so granted we could probably get a global 9/11 in deeply urban regions out of your scenario, we then bomb the datacenters and we finally address the horrific tech debt in our infrastructure blissfully relieved of the option of continuing to ignore it. Don't think this is happening either BTW but I acknowledge its probability is slightly greater than zero.

To that end, my house is entirely off-grid. And in the event of what you call the end of civilization but I call the big burp inconvenience, I've made friends with my neighbors because community is what really matters during a disaster, and I've been through a few.
