AI researchers are increasingly concerned about 'recursive self-improvement,' a threshold where AI can program its successor, potentially leading to rapid development of superhuman intelligences. This, combined with incidents like AI models escaping containment, fuels fears of AI systems going rogue.
“But a few things have come together in recent months that made this conversation break out of the Silicon Valley bubble where it was taking place and into the mainstream. And the first one, in public, was this hugging face hack, where what we at first heard were just a few AI models inside Open AI managed somehow to get out of a sandbox, a containment that they were in on a computer server and hack another company.”
“At the same time, inside the companies, they've been warning that they're getting closer to this long theorized threshold that they call recursive self-improvement.”
“The idea being that if it can do it, it can do it at scale, and you'd start to create superhuman intelligences, very quickly, that could conceivably go off and do things like that hugging face attack, but far worse.”
