Safety ≠ alignment (but they’re close!), published by Steve Byrnes on April 6, 2022 on The AI Alignment Forum.
Part of the “Intro to brain-like-AGI safety” post series.
(If you’re already an AGI safety expert, you can probably skip this short post—I don’t think anything here is new, or too specific to brain-like AGIs.)
11.1 Post summary / Table of contents
In the previous post, I talked about “the alignment problem” for brain-like AGIs. Two points are worth emphasizing: (1) the alignment problem for brain-like AGIs is currently unsolved (just like the alignment problem for any other type of AGI), and (2) solving it would be a giant leap towards AGI safety.
That said, “solving AGI alignment” is not exactly the same as “solving AGI safety”. This post is about how the two may come apart, at least in principle.
As a reminder, here’s the terminology:
“AGI alignment” (previous post) means that an AGI is trying to do things that the AGI designer had intended for it to be trying to do. This notion only makes sense for algorithms that are “trying” to do something in the first place. What does “trying” mean in general? Hoo boy, that’s a whole can of worms. Is a sorting algorithm “trying” to sort numbers? Or is it merely sorting them?? I don’t want to go there. For this series, it’s easy. The “brain-like AGIs” that I’m talking about can definitely “try” to do things, in exactly the same common-sense way that a human can “try” to get out of debt.
“AGI safety” (Post #1) is about what the AGI actually does, not what it’s trying to do. AGI safety means that the AGI’s actual behavior does not lead to a “catastrophic accident”, as judged by the AGI’s own designers.
Thus, these are two different things. And my goal in this post is to describe how they may come apart:
Section 11.2 is “alignment without safety”. A possible story would be: “I wanted my AGI to mop the floor, and my AGI did in fact try to mop my floor, but, well, it’s a bit clumsy, and it seems to have accidentally vaporized the entire universe into pure nothingness.”
Section 11.3 is “safety without alignment”. A possible story would be: “I don’t really know what my AGI is trying to do, but it is constrained, such that it can’t do anything catastrophically dangerous even if it wanted to.” I’ll go through four special cases of safety-without-alignment: “boxing”, “data curation”, “impact limits”, and “non-agentic AI”.
To skip to the final answer, my takeaway is that, although it is not technically correct to say “AGI alignment is necessary and sufficient for AGI safety”, it’s damn close to correct, at least in the brain-like AGIs we’re talking about in this series.
11.2 Alignment without safety?
This is the case where an AGI is aligned (i.e., trying to do things that its designers had intended for it to try to do), but still causes catastrophic accidents. How?
One example: maybe, as designers, we didn’t think carefully about what we had intended for the AGI to do. John Wentworth gives a hypothetical example here: humans ask the AGI for a nuclear fusion power plant design, but they neglect to ask the follow-up question of whether the same design makes it much easier to make nuclear weapons.
Another example: maybe the AGI is trying to do what we had intended for it to try to do, but it screws up. For example, maybe we ask the AGI to build a new better successor AGI, that is still well-behaved and aligned. But the AGI messes up. It makes a successor AGI with the wrong motivations, and the successor gets out of control and kills everyone.
I don’t have much to say in general about alignment-without-safety. But I guess I’m modestly optimistic that, if we solve the alignment problem, then we can muddle our way through to safety. After all, if we solve the alignment problem, then we’ll be able to...
