This table explores the ethical expected-value of a career in AI safety, under different opinions about AI and the long-term future. I made it for considering the robustness of the value of my possible career choice to different ways my opinions could change, but it may be useful to others also considering a career in AI safety, or for convincing people more skeptical of fast AI timelines that safety work is still important.

My main finding is that you need to hold a pretty specific combination of confident beliefs for AI safety work not to seem tremendously valuable in expected impact, and I personally find those beliefs pretty untenable.

For the skeptical: This doesn't mean we're all going to die! - Just that this work seems like a good opportunity because the stakes are so high relative to the chances of having a positive impact, even if we're very likely to be fine anyway. 

For the non-skeptical: Reasonable people certainly disagree whether the median scenario looks anything like "we're fine", and I'm very sympathetic to that too. It's just that for answering the binary question of "should more people be working on this?", the median scenario is surprisingly unimportant right now. I'm showing that even people with heavy skepticism and very slow AI timelines should agree that more AI safety work is important, so long as they have some reasonable uncertainties in their views. 

Read the “Explanation” section first if you’re confused about anything. You may have to shift+scroll to see the whole table. Here is a google sheet where you can see the implications of your own opinion.

Main takeaway: 
You need to hold a pretty specific combination of confident beliefs for AI safety work not to seem tremendously valuable in expected impact. 

i.e. something like those in the leftmost column: safety work is likely to be well-staffed, yet very unlikely to be useful, and humanity will go extinct soon with very high probability anyway. I personally find those beliefs pretty untenable - especially the amount of certainty they require about AGI and the long-term future of humanity.
 

Alternate refutations of the importance of AI safety work 
(and my responses):

• You could believe that the future of humanity is net negative and humans should be wiped out.
  → But would a world ruled by some sort of paperclips-style AGI be better than humanity under your moral framework? Surely it would be much worse for the environment, and all other life on earth. In any case, the advantage of having humans around for a while longer is that we have more time to figure out what would be morally best for the universe, then do it. Or, better yet, program an actually aligned AGI to do it. Personally I'd prefer we be replaced by wildlife, or a universe of little happy things, rather than a misaligned AGI turning the planet into paperclips or something. See also: suffering risks which might be caused by a misaligned AGI, or the possibility that we might be able to abolish all suffering of humans and all other animals in the future.
   
• You might think the long-term future is unpredictable and virtually impossible to influence intentionally like this. 
  → Sure, the long-term impact of pretty much all our actions has tremendous sign uncertainty, meaning long-term considerations usually wash-out compared to short-term ones, but in this case, are you really so sure? Extinction seems like a pretty clear-cut case in terms of the direction of long-term expected value, relatively speaking. Still, it's possible that there will be a strong enough flow of negative (unforeseen) consequences to outweigh the positives. We should take these seriously, and try to make them less unforseen so we can correct for them, or at least have more accurate expected-value estimates. But given what's at stake, they would need to be pretty darn negative to pull down the expected values enough to outweigh a non-trivial risk of extinction.
   
• You could very strongly believe a different view of population ethics, or very strongly reject anything like consequentialism, giving less than a 0.01% credence to any moral theory which values the mere existence of happy beings in the future. A ~0.01% credence would let you sit in the second column, but still reject AI safety work. 
  → But 0.01% credence is pretty damn sure. Are you sure you’re so sure? See moral uncertainty for a discussion of how you should act when you’re uncertain about the correct moral framework. Regardless, safety is still worth working on if you fall in any except the first two columns, even if you certainly don’t care about the existence or nonexistence of future beings.
   
• You don’t think we’re under any obligation to do what seems morally best. 
  →  Perhaps, sure, and probably no one should make you feel guilty for not devoting your career to this. But this is a great opportunity to have a very large positive impact.
   
• You might react negatively to things which feel like Pascal’s mugging. 
  → See Robert Miles' video for a response to this criticism of AI safety work. Basically, it’s worth reasoning about expected values based on evidence.
   
• You think that most of the important work is done by a small fraction of the AI alignment researchers, so you will personally be unlikely to have an impact as strong as the table suggests. 
  → This is true, but before you go into the field you may have no information about where in the efficacy spectrum of AI researchers you will fall. Rather than assuming you will fall near the median, it makes sense to assume you will be like a random person drawn from the distribution of AI safety researchers, in which case your expected contribution is the same as the average contribution, not the median. This is why this table is for a “random” person in the field, rather than the median person (who would have smaller expected impact). Upon entering the field (or just on reviewing your own personal fit) you may receive sufficiently strong indications that you will not be able to be a part of the most efficacious fraction of AI safety researchers. After reassessing the expected value of your impact, it may make sense to switch careers, especially if the field ever becomes primarily funding-constrained and you believe new hires may have a bigger expected impact than you. However, this issue of replaceability reducing your counterfactual impact is much less of a worry in AI alignment than most other fields, and less of a worry in general than you might expect. There seems to be a lot of room to grow the whole field of AI safety right now, so it’s far from a zero-sum game. 
   
• You think there are higher expected-value considerations pushing in the other direction, or plenty of other highly positive careers a potential AI safety researcher could go into instead, and perhaps their expected-value is just harder to quantify. 
  → Fair enough, that’s a matter of evidence. I’m sure there are plenty of other careers out there with huge positive moral impacts. The more we can identify the better.
   
• Your priors are just very low, perhaps due to anthropic reasoning that this can’t be the most important century, or that such a proliferation of future generations can't exist.  
  → You are entitled to your priors, but you ought to be very careful with anthropic reasoning. Using it to lower your priors this much seems almost as bad as using it to support something like the doomsday argument. Personally, I’m quite a fan of “fully non-indexical” anthropic reasoning, where you must “condition on all evidence - not just on the fact that you are an intelligent observer, or that you are human, but on the fact that you are a human with a specific set of memories”, in which case I think anthropic reasoning tells you very little about this issue. (podcast for clarification)
   

Explanation 

AI (Artificial Intelligence) safety research seems to have tremendous expected moral value. Most of this expected value probably does not come from the median scenario, so the work will probably look less impactful in hindsight, but this should be no argument against it, as the potential impacts are just so huge, and their probabilities seem plausibly nontrivial. Additionally, there is a range of possibly tractable and useful research areas, widening further as AI capabilities increase.
 

My credence in (strong) AGI soon:

My definition of strong AGI (Artificial General Intelligence): A system which can accomplish virtually any (non human-biology-specific) useful objective more effectively than the most effective person in that field. This includes reasoning about the world (and the humans in it), and making predictions.

• Within 10 years: ~10%,    Within 20 years: ~20%,    Within 50 years: ~50%
• I’m very uncertain of these, and I hold them very weakly. They’re largely based on priors. Ideally, there would be much more solid research informing all of these credences, but I basically just have to go with what I think for now. For alternative numbers (mostly faster), see:
  • Experts' Predictions about the Future of AI
  • Draft report on AI timelines by Ajeya Cotra
  • Metaculus compilation: Where is the AGI Roadmap?
  • Metaculus compilation: AI safety and timelines
  • Metaculus predictions on “Date Weakly General AI is Publicly Known”
  • Google's "Pathways" plans to immediately start implementing more AGI-like architectures
  • DeepMind's stated aim is to "solve intelligence, developing more general and capable problem-solving systems, known as artificial general intelligence (AGI)."
  • OpenAI's mission statement: "We will attempt to directly build safe and beneficial AGI ... "

Why have you looked at mostly slower timelines here when most of the sources you link have faster timelines? 

1. For my selfish personal use, I wanted to see just how far my opinions would have to change before a career in AI safety would no longer seem extremely beneficial. Then, seeing that they would have to move a tremendous amount, I can very confidently commit to AI safety without worrying about reconsidering my career choice in light of new evidence every day.  (Just every few years or something)
    
2. The people with fast timelines are probably more likely to buy into the usefulness of AI safety work already (I think?), so showing that even most slow-timeline scenarios have great expected value is useful for convincing more mainstream people about the value of AI safety work. 
    

Based on (hurdles still needed to clear before AGI): 

• Internal model of the world which can be updated and have inconsistencies resolved.
• Long-term planning (abstraction from immediate actions to long-term plans and back)
• Few-shot learning and immediate dynamic adaptation to new environments

These are not independent; progress on one is likely to be useful to the others. On the other hand, I’m sure I’m missing some.
 

AGI development paths / warning signs (conditional on AGI): 

• Breakthrough out of the blue: ~10% ( ~0.5% in peacetime, rising significantly in (cold) war, scaling with intensity of war. ~40% chance of pivotal AGI development occurring during (cold) war)
• One team over the course of a few years (some clearish signs, things getting very strange): 20%
• Multiple teams over the course of a few years (multiple clearish signs, things getting very strange): 40%
• Anything slower / more multipolar: 20%
• US/EU/AU/UK ahead in development (not exclusive with other options): 60%
• AGI has most of its potential for existential impact before singularity: 70%

Again, I hold these credences very weakly. Substitute your own.
 

Impacts of AGI:

• Implications are massively underestimated by most people (for strong AGI).
• It’s such a pivotal technology that it seems impossible to picture how the world will look in 100 years without knowing how (or whether) AGI goes.
   

Misalignment risk:

Since machine-learning systems are usually trained to achieve some goal, they usually take on some internal representation of this trained-goal as their intrinsic goal. Or at least they take on an approximation of the external goal which works on the training set. For example, evolution’s goal of “inclusive reproductive fitness” produced our jumble of values which were aligned with that in our past evolutionary environment, but no longer necessarily align with maximizing inclusive reproductive fitness, since many things (eg. contraceptives, abundant sugar, technology, global society) have taken us out of evolution’s “training environment”. See mesa-optimization and inner-alignment (video).

AIs can have just about any intrinsic goal, and just about any goal is compatible with superhuman intelligence. A “misaligned” AI would be any AI with an internal goal not fully aligned with our values, with the discrepancy eventually being actualized in some important way (eg. when its environment starts to differ from the training environment). See the orthogonality thesis (video).

An AI is incentivized to do whatever it can to raise the probability of achieving its intrinsic goals. Some ways that a misaligned AI could fail to have its goals achieved: Humans shutting it down; Humans changing its goals; Humans discovering that it is misaligned before it is powerful enough that humans are no longer able to control it. See instrumental convergence (video).

• Misalignment risk seems greatest during wartime (but probably not dominated by wartime risk)
• Outside of wartime, surely no one would be stupid enough to let a paperclips-style single-optimizer go wild. Right? Still, nonzero probability that one may (stupidly) be developed and escape, maybe just because it’s easier to train an AGI to optimize for one thing, like it’s easier to train GPT to optimize next-word performance.
• To me, the most likely scenario is a subtler, mesa-alignment type problem. There will be warning signs in stupider iterations being deceptive or competently optimizing for the wrong thing, but perhaps the applied fix turns out to be more of a bandaid than anticipated, until too late.
• What might the first AGIs look like? Optimizing actors (hopefully not)? Feedback responding actors? Queryable world models? Risk depends on that.
• Overall, hard to say (especially taking into account existing trajectory of AI safety work), but significant probability of subtle misalignment, which might not be fixable until too late.
• Again, the largest potential for counterfactual impact may not necessarily come from scenarios like the median (although in this case it might)
   

Existential risk:

Definition of existential risk

• Misaligned AGI seems like the most plausible path to permanently cutting off humanity’s potential (See “The Precipice” for a comparison with other risks).
• Forgoing trillions of descendant-years of potential flourishing throughout the galaxy would probably be very bad.
• A sufficiently cognitively powerful system will be able to outwit humanity at every turn, and do whatever it wants.
• Any interaction with humans is enough of a channel to allow a superintelligence to manipulate them, escape, and do whatever it wants.
• If it determined humanity to be a threat to its goals, a superintelligence could, for example, remotely trick, blackmail, or manipulate someone in a biolab to unknowingly synthesize a virus which might wipe out humanity. (or not - superintelligence could probably come up with something much more effective).

The main way we might make a misaligned powerful AI and still be lucky enough to not all die is if it happens to be incompetent enough in some relevant area far outside its training set that we can leverage that area to outwit and stop it. In other words, If the AI has low alignment robustness, but also low capability robustness, we might be ok. 
 

Opportunities for intervention:

There are many important, neglected, tractable (enough) research topics to pursue:

• Reliability and alignment-robustness to train/test distributional shifts, with an extremely low tolerance for error.
• Inverse reinforcement learning / value learning
• Corrigibility
• Interpretability
• Making models which output only what they "believe" under some internal representation
• Theoretical work on what a safe AGI could look like
• Many more (I’m not an expert, but this is proof of concept for some tractable areas):
  • Alignment Newsletter - Unsolved Problems in ML Safety (paper)
  • 2021 AI Alignment Literature Review and Charity Comparison
  • Eliciting latent knowledge 
     

Expected-value of the long-term future:

This is only upper-bounded by the laws of physics and the time until all the stars die out. The lower bound depends on your optimism for the human species. The potential is vast - If they aren’t extinct, far future beings in a post-scarcity society will have had the time to figure out how to be much happier, more fulfilled, more numerous, and more ethical, (or to change their biologies to achieve this) spreading more of whatever is good throughout the galaxy, or preserving or restoring it if it was already there. 

A note on expected values: Unless you give a vanishingly small probability to futures where we expand through the universe, or develop mind-uploading technology, these should influence your expected values for the number of beings in the future, pulling your expected numbers up far above the median scenario. And if you think the probability is vanishingly small, it still has to vanish as fast as the potential population increases - getting down to less than about 1 in 10⁵⁰ once you start talking about scenarios with virtual-mind carrying machines expanding through the universe. 

Put differently, most of the people who will ever live in the future possible histories of the universe will probably live in fairly low-probability scenarios, made up for by their extreme proliferation in that low-probability scenario (unless you think extreme proliferation is the median scenario, or extreme proliferation is even more extremely unlikely). This is somewhat akin to where we find ourselves today, as viewed from the distant (geologic-time) past.

Let me know if you have any feedback.
