> why are we worried about the virus but not the incompetency of those who are responsible for setting up the sandbox?
Right. And not just the incompetency of those who set the sandbox, but also the incompetency of those who set up the systems that fell to the virus, while most of the computers attacked did not fail.
There's no reason at all to fall into fatalism and think "zomg LLMs are too good, they can hack anything". They simply can't: the world keeps on running just fine. There are people out there who can secure systems and now doubly-so thanks to the use of LLMs who are incredibly good at helping us automate tedious stuff.
So, yes, OpenAI shouldn't write poor sandboxes but defenders shouldn't get a free-pass to set up sloppy systems that can be trivially hacked. We're passed that point: poorly secured systems aren't acceptable anymore.
