Walking takes less than a minute, and you can simply drive it through the wash and walk back home afterward."
I've tried several other variants of this question and I got similar failures.
However I am still mystified by the safety aspect. They say the model has greatly improved resistance. But their own safety evaluation says 8% of the time their automated adversarial system was able to one-shot a successful injection takeover even with safeguards in place and extended thinking, and 50% (!!) of the time if given unbounded attempts. That seems wildly unacceptable - this tech is just a non-starter unless I'm misunderstanding this.

However, if we frame the question this way, I would imagine there are many more low-hanging fruit before we question the utility of LLMs. For example, should some humans be dumping 5-10 kWh/day into things like hot tubs or pools? That's just the most absurd one I was able to come up with off the top of my head. I'm sure we could find many others.
It's a tough thought experiment to continue though. Ultimately, one could argue we shouldn't be spending any more energy than what is absolutely necessary to live. (food, minimal shelter, water, etc) Personally, I would not find that enjoyable way to live.
