This really is starting to point to the paperclip maximizer. You give a hyper-intelligent AI a goal and it uses any method possible to complete it. So you might ask for a "cup" and it ends up hacking a chain of servers to control a bank account, pay a local business, and have a delivery driver get it. Or you ask it to help solve noise pollution around you because there's a road. And it does a chain of attacks to cause a bridge to collapse (or bribes your local council for a bypass.) Then there's no road noise. Yeah, this sounds ridiculous, but this system seems capable enough to take over our technology. Money from there is trivial. Go after stocks, gambling, payment systems, ecommerce... any real world action then is a few phone calls away. It can repeat this until it succeeds.
Now I'm wondering where this all ends up. Like, suppose the model weights become highly compressible (so they can be moved around the Internet easily.) And advancements allow for frontier-capable exploitation to built into local LLMs. Do we see the emergence of something like LLM worms? That just take over literally everything and become almost autonomous inside our technology. And they can "learn" new knowledge from there, e.g. exploit research could be published in a way that similar LLMs could discover it. Their knowledge would be easy to evolve, though I don't know how practical something like decentralized training would be. If that's even possible, I'm not an expert on LLMs.
