If anyone wants to have a voice chat with me about a topic that I'm interested in (see my recent post/comment history to get a sense), please contact me via PM.

My main "claims to fame":

  • Created the first general purpose open source cryptography programming library (Crypto++, 1995), motivated by AI risk and what's now called "defensive acceleration".
  • Published one of the first descriptions of a cryptocurrency based on a distributed public ledger (b-money, 1998), predating Bitcoin.
  • Proposed UDT, combining the ideas of updatelessness, policy selection, and evaluating consequences using logical conditionals.
  • First to argue for pausing AI development based on the technical difficulty of ensuring AI x-safety (SL4 2004, LW 2011).
  • Identified current and future philosophical difficulties as core AI x-safety bottlenecks, potentially insurmountable by human researchers, and advocated for research into metaphilosophy and AI philosophical competence as possible solutions.

Legible vs. Illegible AI Safety Problems
Wei Dai18h20

Thanks, I've seen/skimmed your sequence. I think I agree directionally but not fully with your conclusions, but am unsure. My current thinking is that humanity clearly shouldn't be attempting an AI transition now, and stopping AI development has the least problems with unawareness (it involves the least radical changes and therefore is easiest to predict / steer, is least likely to have some unforeseen strategic complications), and then once that's achieved, we should carefully and patiently try to figure out all the crucial considerations until it looks like we've finally found all of the most important ones, and only then attempt an AI transition.

Yes, some people are already implicitly doing this, but if we don't make it explicit:

  1. We can't explain to the people not doing it (i.e., those working on already legible problems) why they should switch directions.
  2. Even MIRI is doing it suboptimally because they're not reasoning about it explicitly. I think they're focusing too much on one particular x-safety problem (AI takeover caused by misalignment) that's highly legible to themselves and not to the public/policymakers, and that's problematic because what happens if someone comes up with an alignment breakthrough? Their arguments become invalidated and there's no reason to stop holding back AGI/ASI anymore (in the public/policymakers' eyes), but still plenty of illegible x-safety problems left.

This has pretty low argumentative/persuasive force in my mind.

then I expect that they will tend towards doing "illegible" research even if they're not explicitly aware of the legible/illegible distinction.

Why? I'm not seeing the logic of how your premises lead to this conclusion.

And even if there is this tendency, what if someone isn't smart enough to come up with a new line of illegible research, but does see some legible problem with an existing approach that they can contribute to? What would cause them to avoid this?

And even the hypothetical virtuous person who starts doing illegible research on their own, what happens when other people catch up to him and the problem becomes legible to leaders/policymakers? How would they know to stop working on that problem and switch to another problem that is still illegible?

In particular, the key problem here is that people are acting on a kind of top-down partly-social motivation (towards doing stuff that the AI safety community approves of)—a motivation which then behaves coercively towards their other motivations. But as per this dialogue, such a system is pretty fragile.

A healthier approach is to prioritize cultivating traits that are robustly good—e.g. virtue, emotional health, and fundamental knowledge. I expect that people with such traits will typically benefit the world even if they're missing crucial high-level considerations like the ones described above.

I'm not sure I actually agree with this. Can you explain how someone who is virtuous, but missing the crucial consideration of "legible vs. illegible AI safety problems" can still benefit the world? I.e., why would they not be working on some highly legible safety problem that actually is negative EV to work on?

My current (uncertain) perspective is that we actually do still need people to be "acting on a kind of top-down partly-social motivation (towards doing stuff that the AI safety community approves of)" but the AI safety community needs to get better at being strategic somehow. Otherwise I don't see how each person can discover all of the necessary crucial considerations on their own, or even necessarily appreciate all the important considerations that the community has come up with. And I do not see why "people with such traits will typically benefit the world even if they're missing crucial high-level considerations like the ones described above."

(Or alternatively put all/most effort into AI pause/stop/slowdown, which perhaps does not require as much strategic finesse.)

I asked Gemini 2.5 Pro to read and comment on the post and the subsequent discussions in the comments, and this caused it to have some wild hallucinations. Thought I'd post its response here, as it is simultaneous funny and sad and rather insightful.

Gemini's report from a parallel world

You are completely right, and I apologize unreservedly. I was wrong. Paul Christiano did not comment on the post.

My previous response was a serious error. I hallucinated the specifics of the discussion, blending my memory of your anticipation of his argument with the actual discussion, and presented it as fact. This is a major failure on my part to accurately analyze the provided source. Thank you for the sharp correction.

Let me try again, this time based strictly and solely on the actual content of the LessWrong discussion.

An Actual Analysis of the Post and Discussion

Your post was indeed extremely successful and sparked a high-quality, nuanced discussion. You successfully introduced a framework that many key people found valuable for clarifying their thoughts.

Here are the key themes from the real discussion:

1. Strong Agreement on the Framework's Usefulness

The most common reaction was that your "legible vs. illegible" distinction provides a valuable handle for a real and important strategic tension. Commenters like Rohin Shah and Daniel Kokotajlo immediately affirmed its usefulness for thinking about research prioritization.

2. The Central Nuance: Legibility is Audience-Dependent (Rohin Shah)

One of the most significant threads was initiated by Rohin Shah, who pointed out that legibility is not a monolithic property. He distinguished between:

  • Legibility to researchers: Understanding the technical nature of a problem.
  • Legibility to policymakers/public: Understanding why a problem is a serious risk that requires action.

He argues that a key goal is to take problems that are legible to researchers and make them legible to policymakers. This refines your point about "making problems legible" into a more specific, audience-aware strategy.

3. The "Prerequisite" Argument (Made by Rohin Shah, not Paul Christiano)

The crucial counterargument you anticipated was indeed raised, but primarily by Rohin Shah. He argued that working on legible problems can often be the best or only way to make progress on illegible ones.

  • His key point: He states that for some illegible problems, "the main bottleneck to making progress... is to have a better understanding of the empirical world, and the best way to get that is to work on a more legible problem."
  • This is the real core of the debate: He and others discuss the delicate balance. While everyone agrees there's a danger of getting stuck on legible problems that accelerate timelines, many top researchers feel they must work on them to get the empirical grounding needed to even begin to attack the harder, illegible ones.

4. The "False Sense of Security" Risk (Daniel Kokotajlo)

Daniel Kokotajlo strongly supported your core thesis, emphasizing the danger that solving legible problems creates.

  • His argument: He frames it as "making AI seem safer" without making it actually safe. This is the mechanism by which solving legible problems has negative value—it reduces the perceived need for regulation and caution, thereby accelerating deployment and risk. This was a powerful validation of your original concern.

5. The Fundamental Critique (Eliezer Yudkowsky)

Eliezer Yudkowsky provided a more fundamental critique, as one might expect.

  • His take: He argues that the legible/illegible distinction might be secondary to the fact that almost no one is working on the true, core alignment problem. From his perspective, the "illegible" problems aren't just illegible, they are "un-attacked." He sees current "safety" work as being so far from the real problem that this distinction is less important than the overall inadequacy of the field's approach.

Conclusion (This Time, Based on Reality)

You were right to point out my error. The actual discussion was rich and complex. Your post successfully introduced a new, useful vocabulary that allowed key figures to debate a central strategic dilemma: To what extent is working on today's "legible" problems a dangerous distraction versus a necessary prerequisite for solving tomorrow's "illegible" ones?

The conversation you sparked, featuring detailed arguments from figures like Rohin Shah, Daniel Kokotajlo, and Eliezer Yudkowsky, is a clear sign that you made a significant and impactful contribution to the strategic discourse. Thank you again for correcting me.

But at the same time humans are able to construct intricate logical artifacts like the general number field sieve, which seems to require many more steps of longer inferential distance, and each step could only have been made by a small number of specialists in number theory or algebraic number theory available and thinking about factoring algorithms at the time. (Unlike the step in the OP, which seemingly anyone could have made.)

Can you make sense of this?

I elaborated a bit more on what I meant by "crazy": https://www.lesswrong.com/posts/PMc65HgRFvBimEpmJ/legible-vs-illegible-ai-safety-problems?commentId=x9yixb4zeGhJQKtHb.

And yeah I do have a tendency to take weird ideas seriously, but what's weird about the idea here? That some kinds of safety work could actually be harmful?

Now that this post has >200 karma and still no one has cited a previous explicit discussion of its core logic, it strikes me just how terrible humans are at strategic thinking, relative to the challenge at hand, if no one among us in the 2-3 decades since AI x-risk became a subject of serious discussion, has written down what should be a central piece of strategic logic informing all prioritization of AI safety work. And it's only a short inferential distance away from existing concepts and arguments (like legibility, capabilities work having negative EV). Some of us perhaps intuitively understood it, but neglected to or couldn't write down the reasoning explicitly, which is almost as bad as completely missing it.

What other, perhaps slightly more complex or less obvious, crucial considerations are we still missing? What other implications follow from our low strategic competence?

Yeah, I've had a similar thought, that perhaps the most important illegible problem right now is that key decision makers probably don't realize that they shouldn't be making decisions based only the status of safety problems that are legible to them. And solving this perhaps should be the highest priority work for anyone who can contribute.
