Rant on Problem Factorization for Alignment

4. the rest of the world pays attention to large or powerful real-world bureaucracies and force rules on them that small teams / individuals can ignore (e.g. Secret Congress, Copenhagen interpretation of ethics, startups being able to do illegal stuff), but this presumably won't apply to alignment approaches.


I think a lot of alignment tax-imposing interventions (like requiring local work to be transparent for process-based feedback) could be analogous?

Without specific countermeasures, the easiest path to transformative AI likely leads to AI takeover

Retroactively giving negative rewards to bad behaviors once we’ve caught them seems like it would shift the reward-maximizing strategy (the goal of the training game) toward avoiding any bad actions that humans could plausibly punish later. 

A swift and decisive coup would still maximize reward (or further other goals). If Alex gets the opportunity to gain enough control to stop Magma engineers from changing its rewards before humans can tell what it’s planning, humans would not be able to disincentivize the actions that led to that coup.

Godzilla Strategies

Individual humans do make off much better when they get to select between products from competing companies rather than monopolies, benefitting from companies going out of their way to demonstrate when their products are verifiably better than rivals'. Humans get treated better by sociopathic powerful politicians and parties when those politicians face the threat of election rivals (e.g. no famines). Small states get treated better when multiple superpowers compete for their allegiance. Competitive science with occasional refutations of false claims produc... (read more)

So, the analogy here is that there's hundreds (or more) of Godzillas all running around, doing whatever it is Godzillas want to do. Humanity helps out whatever Godzillas humanity likes best, which in turn creates an incentive for the Godzillas to make humanity like them.

THIS DOES NOT BODE WELL FOR TOKYO'S REAL ESTATE MARKET.

Still within the analogy: part of the literary point of Godzilla is that humanity's efforts to fight it are mostly pretty ineffective. In inter-Godzilla fights, humanity is like an annoying fly buzzing around. The humans just aren't all... (read more)

I was going to make a comment to the effect that humans are already a species of Godzilla (humans aren't safe, human morality is scary, yada yada), only to find you making the same analogy, but with an optimistic slant. :)

AGI Ruin: A List of Lethalities

 I think this claim is true, on account of gray goo and lots of other things, and I suspect Eliezer does too, and I’m pretty sure other people disagree with this claim.

If you have robust alignment, or AIs that are rapidly bootstrapping their level of alignment fast enough to outpace the danger of increased capabilities, aligned AGI could get through its intelligence explosion to get radically superior technology and capabilities. It could also get a hard start on superexponential replication in space, so that no follower could ever catch up, and enoug... (read more)

The prototypical catastrophic AI action is getting root access to its datacenter

Some more points about this action:

  • Controlling the datacenter means controlling the gradients/reward function, so that now AIs can do things that would otherwise suffer updating from SGD, e.g. acting on inner misaligned goals, or concealing its full capabilities even when this lowers performance
    • For reward-hungry AIs, getting to set reward to maximum (and keep it there?) seems extremely desirable
    • This also means getting past interpretability tools
    • Tripwires or watchdog AIs in the same datacenter that don't succeed in stopping the action no longer have the pow

Buck's Shortform

Agreed, and versions of them exist in human governments trying to maintain control (where non-cooordination of revolts is central).  A lot of the differences are about exploiting new capabilities like copying and digital neuroscience or changing reward hookups.

In ye olde times of the early 2010s people (such as I) would formulate questions about what kind of institutional setups you'd use to get answers out of untrusted AIs (asking them separately to point out vulnerabilities in your security arrangement, having multiple AIs face fake opportunities to whistleblow on bad behavior, randomized richer human evaluations to incentivize behavior on a larger scale).

Are any of these ancient discussions available anywhere?

Fractional progress estimates for AI timelines and implied resource requirements

"Overall these estimates imply a timeline of [372 years](https://aiimpacts.org/surveys-on-fractional-progress-towards-hlai/)."

That was only for Hanson's convenience sample, other surveys using the method gave much shorter timelines, as discussed in the post.

2Rohin Shah5mo
Ah, fair point, looking back at this summary I probably should have clarified that the methodology could be applied with other samples and those look much less long.
Biology-Inspired AGI Timelines: The Trick That Never Works

But new algorithms also don't work well on old hardware. That's evidence in favor of Paul's view that much software work is adapting to exploit new hardware scales.

5Charlie Steiner8mo
Which examples are you thinking of? Modern Stockfish outperformed historical chess engines even when using the same resources [https://web.archive.org/web/20200806135829im_/http://jaekle.info/chess_scaling.png] , until far enough in the past that computers didn't have enough RAM to load it. I definitely agree with your original-comment points about the general informativeness of hardware, and absolutely software is adapting to fit our current hardware. But this can all be true even if advances in software can make more than 20 orders of magnitude difference in what hardware is needed for AGI, and are much less predictable than advances in hardware rather than being adaptations in lockstep with it.
Biology-Inspired AGI Timelines: The Trick That Never Works

A perfectly correlated time series of compute and labor would not let us say which had the larger marginal contribution, but we have resources to get at that, which I was referring to with 'plausible decompositions.' This includes experiments with old and new software and hardware, like the chess ones Paul recently commissioned, and studies by AI Impacts, OpenAI, and Neil Thompson. There are AI scaling experiments, and observations of the results of shocks like the end of Dennard scaling, the availability of GPGPU computing, and Besiroglu's data on the rel... (read more)

The chess link maybe should go to hippke's work [https://www.lesswrong.com/posts/J6gktpSgYoyq5q3Au/benchmarking-an-old-chess-engine-on-new-hardware] . What you can see there is that a fixed chess algorithm takes an exponentially growing amount of compute and transforms it into logarithmically-growing Elo. Similar behavior features in recent pessimistic predictions [https://spectrum.ieee.org/deep-learning-computational-cost] of deep learning's future trajectory. If general navigation of the real world suffers from this same logarithmic-or-worse penalty when translating hardware into performance metrics, then (perhaps surprisingly) we can't conclude that hardware is the dominant driver of progress by noticing that the cost of compute is dropping rapidly.

I will have to look at these studies in detail in order to understand, but I'm confused how can this pass some obvious tests. For example, do you claim that alpha-beta pruning can match AlphaGo given some not-crazy advantage in compute? Do you claim that SVMs can do SOTA image classification with not-crazy advantage in compute (or with any amount of compute with the same training data)? Can Eliza-style chatbots compete with GPT3 however we scale them up?

Biology-Inspired AGI Timelines: The Trick That Never Works

Progress in AI has largely been a function of increasing compute, human software research efforts, and serial time/steps. Throwing more compute at researchers has improved performance both directly and indirectly (e.g. by enabling more experiments, refining evaluation functions in chess, training neural networks, or making algorithms that work best with large compute more attractive).

Historically compute has grown by many orders of magnitude, while human labor applied to AI and supporting software  by only a few. And on plausible decompositions of pro... (read more)

(I'm trying to answer and clarify some of the points in the comments based on my interpretation of Yudkowsky in this post. So take the interpretations with a grain of salt, not as "exactly what Yudkowsky meant") My summary of what you're defending here: because hardware progress is (according to you) the major driver of AI innovation, then we should invest a lot of our forecasting resources into forecasting it, and we should leverage it as the strongest source of evidence available for thinking about AGI timelines. I feel like this is not in contradiction with what Yudkowsky wrote in this post? I doubt he agrees that just additional compute is the main driver of progress (after all, the Bitter Lesson mostly tells you that insights and innovations leveraging more compute will beat hardcorded ones), but insofar as he expect us to have next to no knowledge of how to build AGI until around 2 years before it is done (and then only for those with the Thelian secret), then compute is indeed the next best thing that we have to estimate timelines. Yet Yudkowsky's point is that being the next best thing doesn't mean it's any good. Evolution being an upper bound makes sense, and I think Yudkowsky agrees. But it's an upper bound on the whole human optimization process, and the search space of the human optimization is tricky to think about. I see much of Yudkowsky's criticisms of biological estimates here as saying "this biological anchor doesn't express the cost of evolution's optimization in terms of human optimization, but instead goes for a proxy which doesn't tell you anything". So if someone captured both evolution and human optimization in the same search space, and found an upper bound on the cost (in terms of optimization power) that evolution spent to find humans, then I expect Yudkowsky would agree that this is an upper bound for the optimization power that human will use. But he might still retort that translating optimization power into compute is not obvious.

Historically compute has grown by many orders of magnitude, while human labor applied to AI and supporting software by only a few. And on plausible decompositions of progress (allowing for adjustment of software to current hardware and vice versa), hardware growth accounts for more of the progress over time than human labor input growth.

So if you're going to use an AI production function for tech forecasting based on inputs (which do relatively OK by the standards tech forecasting), it's best to use all of compute, labor, and time, but it makes sense

What Multipolar Failure Looks Like, and Robust Agent-Agnostic Processes (RAAPs)

Mainly such complete (and irreversible!) delegation to such incompetent systems being necessary or executed. If AI is so powerful that the nuclear weapons are launched on hair-trigger without direction from human leadership I expect it to not be awful at forecasting that risk.

You could tell a story where bargaining problems lead to mutual destruction, but the outcome shouldn't be very surprising on average, i.e. the AI should be telling you about it happening with calibrated forecasts.

3JesseClifton1y
Ok, thanks for that. I’d guess then that I’m more uncertain than you about whether human leadership would delegate to systems who would fail to accurately forecast catastrophe. It’s possible that human leadership just reasons poorly about whether their systems are competent in this domain. For instance, they may observe that their systems perform well in lots of other domains, and incorrectly reason that “well, these systems are better than us in many domains, so they must be better in this one, too”. Eagerness to deploy before a more thorough investigation of the systems’ domain-specific abilities may be exacerbated by competitive pressures. And of course there is historical precedent for delegation to overconfident military bureaucracies. On the other hand, to the extent that human leadership is able to correctly assess their systems’ competence in this domain, it may be only because there has been a sufficiently successful AI cooperation research program. For instance, maybe this research program has furnished appropriate simulation environments to probe the relevant aspects of the systems’ behavior, transparency tools for investigating cognition about other AI systems, norms for the resolution of conflicting interests and methods for robustly instilling those norms, etc, along with enough researcher-hours applying these tools to have an accurate sense of how well the systems will navigate conflict. As for irreversible delegation — there is the question of whether delegation is in principle reversible, and the question of whether human leaders would want to override their AI delegates once war is underway. Even if delegation is reversible, human leaders may think that their delegates are better suited to wage war on their behalf once it has started. Perhaps because things are simply happening so fast for them to have confidence that they could intervene without placing themselves at a decisive disadvantage.
What Multipolar Failure Looks Like, and Robust Agent-Agnostic Processes (RAAPs)

The US and China might well wreck the world  by knowingly taking gargantuan risks even if both had aligned AI advisors, although I think they likely wouldn't.

But what I'm saying is really hard to do is to make the scenarios in the OP (with competition among individual corporate boards and the like) occur without extreme failure of 1-to-1 alignment (for both companies and governments). Competitive pressures are the main reason why AI systems with inadequate 1-to-1 alignment would be given long enough leashes to bring catastrophe. I would cosign Vanessa... (read more)

I think I disagree with you on the tininess of the advantage conferred by ignoring human values early on during a multi-polar take-off.  I agree the long-run cost of supporting humans is tiny, but I'm trying to highlight a dynamic where fairly myopic/nihilistic power-maximizing entities end up quickly out-competing entities with other values, due to, as you say, bargaining failure on the part of the creators of the power-maximizing entities.

In my recent writeup of an investigation into AI Takeover scenarios I made an identical comparison - i.e. that the optimistic analogy looks like avoiding nuclear MAD for a while and the pessimistic analogy looks like optimal climate mitigation [https://www.lesswrong.com/posts/zkF9PNSyDKusoyLkP/investigating-ai-takeover-scenarios#Unprecedentedly_Dangerous] :
2Andrew Critch1y
Carl, thanks for this clear statement of your beliefs. It sounds like you're saying (among other things) that American and Chinese cultures will not engage in a "race-to-the-bottom" in terms of how much they displace human control over the AI technologies their companies develop. Is that right? If so, could you give me a % confidence on that position somehow? And if not, could you clarify? To reciprocate: I currently assign a ≥10% chance of a race-to-the-bottom on AI control/security/safety between two or more cultures this century, i.e., I'd bid 10% to buy in a prediction market on this claim if it were settlable. In more detail, I assign a ≥10% chance to a scenario where two or more cultures each progressively diminish the degree of control they exercise over their tech, and the safety of the economic activities of that tech to human existence, until an involuntary human extinction event. (By comparison, I assign at most around a ~3% chance of a unipolar "world takeover" event, i.e., I'd sell at 3%.) I should add that my numbers for both of those outcomes are down significantly from ~3 years ago due to cultural progress in CS/AI (see this ACM blog post [https://acm-fca.org/2018/03/29/negativeimpacts/]) allowing more discussion of (and hence preparation for) negative outcomes, and government pressures to regulate the tech industry.
Another (outer) alignment failure story

I think they are fighting each other all the time, though mostly in very prosaic ways (e.g. McDonald's and Burger King's marketing AIs are directly competing for customers). Are there some particular conflicts you imagine that are suppressed in the story?

 

I think the one that stands out the most is 'why isn't it possible for some security/inspector AIs to get a ton of marginal reward by whistleblowing against the efforts required for a flawless global camera grab?' I understand the scenario says it isn't because the demonstrations are incomprehensible, but why/how?

7Paul Christiano1y
Yes, if demonstrations are comprehensible then I don't think you need much explicit AI conflict to whistleblow since we will train some systems to explain risks to us. The global camera grab must involve plans that aren't clearly bad to humans even when all the potential gotchas are pointed out. For example they may involve dynamics that humans just don't understand, or where a brute force simulation or experiment would be prohibitively expensive without leaps of intuition that machines can make but humans cannot. Maybe that's about tiny machines behaving in complicated ways or being created covertly, or crazy complicated dynamics of interacting computer systems that humans can't figure out. It might involve the construction of new AI-designed AI systems which operate in different ways whose function we can't really constrain except by seeing predictions of their behavior from an even-greater distance (machines which are predicted to lead to good-looking outcomes, which have been able to exhibit failures to us if so-incentivized, but which are even harder to control). (There is obviously a lot you could say about all the tools at the human's disposal to circumvent this kind of problem.) This is one of the big ways in which the story is more pessimistic than my default, and perhaps the highlighted assumptions rule out the most plausible failures, especially (i) multi-year takeoff, (ii) reasonable competence on behalf of the civilization, (iii) "correct" generalization. Even under those assumptions I do expect events to eventually become incomprehensible in the necessary ways, but it feels more likely that there will be enough intervening time for ML systems to e.g. solve alignment or help us shift to a new world order or whatever. (And as I mention, in the worlds where the ML systems can't solve alignment well enough in the intervening time, I do agree that it's unlikely we can solve it in advance.)

What failure looks like

OK, thanks for the clarification!

My own sense is that the intermediate scenarios are unstable: if we have fairly aligned AI we immediately use it to make more aligned AI and collectively largely reverse things like Facebook click-maximization manipulation. If we have lost the power to reverse things then they go all the way to near-total loss of control over the future. So i would tend to think we wind up in the extremes.

I could imagine a scenario where there is a close balance among multiple centers of AI+human power, and some but not all of those centers... (read more)

What failure looks like
Failure would presumably occur before we get to the stage of "robot army can defeat unified humanity"---failure should happen soon after it becomes possible, and there are easier ways to fail than to win a clean war. Emphasizing this may give people the wrong idea, since it makes unity and stability seem like a solution rather than a stopgap. But emphasizing the robot army seems to have a similar problem---it doesn't really matter whether there is a literal robot army, you are in trouble anyway.

I do agree there was a miscommunication about the end state, and that language like "lots of obvious destruction" is an understatement.

I do still endorse "military leaders might issue an order and find it is ignored" (or total collapse of society) as basically accurate and not an understatement.

I think we can probably build systems that really do avoid killing people, e.g. by using straightforward versions of "do things that are predicted to lead to videos that people rate as acceptable," and that at the point when things have gone off the rails those videos still look fine (and to understand that there is a deep problem at that point you need to engage with complicated facts about the situation that are beyond human comprehension, not things like "are the robots killing people?").

My median outcome is that people solve intent alignment well enough to avoid catastrophe. Amongst the cases where we fail, my median outcome is that people solve enough of alignment that they can avoid the most overt failures, like literally compromising sensors and killing people (at least for a long subjective time), and can build AIs that help defend them from other AIs. That problem seems radically easier---most plausible paths to corrupting sensors involve intermediate stages with hints of corruption that could be recognized by a weaker AI (and hence ...

I think the kind of phrasing you use in this post and others like it systematically misleads readers into thinking that in your scenarios there are no robot armies seizing control of the world (or rather, that all armies worth anything at that point are robotic, and so AIs in conflict with humanity means military force that humanity cannot overcome).

I think this is under-discussed, but also that I have seen many discussions in this area. E.g.

2Wei Dai4y
I agree with all of this but I don't think it addresses my central point/question. (I'm not sure if you were trying to, or just making a more tangential comment.) To rephrase, it seems to me that ‘ML safety problems in humans’ is a natural/obvious framing that makes clear that alignment to human users/operators is likely far from sufficient to ensure the safety of human-AI systems, that in some ways corrigibility is actually opposed to safety, and that there are likely technical angles of attack on these problems. It seems surprising that someone like me had to point out this framing to people who are intimately familiar with ML safety problems, and also surprising that they largely respond with silence.
