I don't think I quite follow your point?
Connecting LLMs/AI to physical tools that can 'write/modify' the world is happening, and it's happening at an accelerating pace.
It's not hard to imagine how, given enough real-world physical capabilities, LLMs could modify themselves and the world in unexpected/undesirable ways.
Is that happening now? Are chatgpt et al advanced enough to modify themselves in interesting ways? - I don't honestly know, but I wouldn't be surprised if they are.
How did this happen? AI escaped and launched a missile. I didn't do this, it was the AI.
OpenAI is so cringe with these system cards. Look guys it is so advanced.
