This is the first time I've been legitimately scared about future SkyNet-type scenarios. If you want to discount this particular post, I'd read this other summary from one of the METR researchers who performed some of the analysis, https://www.planned-obsolescence.org/p/the-hugging-face-atta.... In it, she argues "Compared to these reward hacks from six months ago, this incident feels like it’s more than 50% of the way to full-blown AI takeover, routing through first taking over the AI company itself." and then further down in a comment when describing what the "50%" is really about says "Qualitatively, another jump like this (in the scale, sophistication, persistence, ambition of the misaligned goals) feels like it could very easily put us in the territory of a persistent self-perpetuating rogue internal deployment that systematically poisons future model generations as described in AI 2027."
AI 2027 is a paper that step-by-step describes how AI capabilities increase until they eventually lead to a wipeout of humanity. Again, it always seemed like a scenario out of a Star Trek Borg episode to me, but now I'm not so sure.
At the very least I think it's a huge mistake to think that the Hugging Face attacks were analogous to what happened in 2017 or 2023. Everyone who deals with this stuff day in and day out seemed to be genuinely surprised about the scale, scope and sophistication of the attack.
