its kinda crazy with literally no guardrails and a goal, the extremes these AI models can actually go to.

Well, to some extent you might be able to argue they're "just" brute-forcing things (especially with unlimited tokens and hours to spend on a task), but they obviously have detailed knowledge to guide them in their attempts, can learn (or at least, persist their newly-gained knowledge), and can use tools.

With a swarm of them working together at speeds humans would be unlikely to match (in terms of iterating on different attempts progressively), it's a lot easier to see how they could overwhelm targets.
