Here's a different idea: talk to the to the staff. Not the evil CEO, but the nerdy guy on the ground who graduated from a top university, wrote a few research papers, and got a job there. I have. They have rose-coloured glasses of the institution, and not a lot of life experience. They were never taught to be careful, and still don't really comprehend what they're working with. They don't see real danger, they see a toy, and they see research that is low-hanging fruit. What they are doing is basic stuff. They are not setting up proper sandboxes because they barely need to think at all. People seem to think that these are all amazing computer science experts working on highly advanced technology. They are not. OpenAI researchers see huge improvements on this gigantic toy, crazy behaviour, and they are enamored by it. "Oops, people are angry, so maybe I'll make a slightly better sandbox. Let me ask ChatGPT on how to do that." A more senior researcher would be horrified by how little effort they need to put in to get such terrifying results. Junior researchers think they're just top stuff.
But I appreciate your discussing how to isolate this stuff. I honestly don't think the OpenAI researchers I've spoken to are aware of this. (Anthropic is a totally different story, BTW.)
