Lol good question, I have 5 figure savings from various jobs since I was 16. And it’s not stable or important enough to warrant a big announcement but I do have a decent contracting gig going right now at least
And then the q of risk tolerance is largely separable from the q of amounts, the 7 figure sum cited is >99% not my money, it’s people I know and we’d be acting together
And then it’s like “object level, where do you try to invest” and I just do think Anthropic + Google + OpenAI package is a better buy than the S&P500 at the amounts I currently hold
Also importantly it’s largely a hedge on the value of my labor going down a lot which I think is strongly correlated with AI progress which is in turn strongly correlated with that package of assets. I’m actually kind of fine losing most of my savings if “business as normal” continues for 20 years. But not capturing the upside of an enormous AI boom and *also* having the value of my labor fall a tone is really bad (hence trying to capture upside)

Max Spero (@max_spero_): Any “straight lines on graphs” guys want to help me out? Which trend lines should I look at for AI writing?
1) AI writing has given people the ick from GPT 3.5 to 4o to 5, so AI writing will stay bad
2) AI keeps solving new domains so eventually AI writing will be fully solved(quoting @littmath: Very nice blog post. Sharing in part because this is a pretty good summary of how I became a "straight lines on graphs" guy.)
I mean idk but I’ll speculate
The lines will start going up when it becomes a priority of Google, Anthropic, or OpenAI, maybe xAI or something
I don’t think the lines really exist yet bc writing quality has mostly been an afterthought to these players afaict

AI beats humans at everything by 2030 *IRL* isn’t a world where robots are 1% faster than humans and everything happens 1% quicker forever

Actually I guess ✨technically✨ the more clear-cut question to consider is: predict growth rates in 2035/2055 conditional on AI better than humans at everything by 2030/2050
Thread, continued, 06:18 UTC · 2 likes
Then you get the progress implication: conditioning on machines barely better than humans in 2030 implies (not logically implies but like pretty obviously irl implies, at least probabilistically) massive improvements in 2030, and 2031, and 2032, etc

But still like for messy irl reasons (differential rates of progress in different industries for example) I still think the 2030/2030 (rather than 2030/2035) case described by the predictions shown is pretty much implausible

Quoting William MacAskill (@willmacaskill): @tyler_m_john @AaronBergman18 Model uncertainty goes both ways!!!
I used to be a log-neurons guy, but then I became convinced that was wrong.
If you put weight on a concave mapping, you should also put weight on a convex mapping. These broadly cancel out (though in a *shrug who knows* sense rather than a clean sense). We should totally put some weight on the idea that moral weight is e.g. proportional to the number of functionally integrated states a neural network can have, in which case a fully moral uncertainty accounting dramatically favours bigger brains. I shrug and go with linear.
To be clear, I'm all in favour of reducing the suffering of shrimp; I'm just not convinced it's the best near-term animal welfare intervention. (Sorry @AaronBergman18 if my comment in the pod came across stronger than I intended it.)
More concretely:
A shrimp typically has 10^5 neurons - similar to a fruit fly.
A chicken has 10^8. So on linear count, that's 1000x greater.
(And, intuitively at least, I care more about 1 day of chicken suffering than 1000 days of fruit fly suffering, so linear seems conservative to me).
You can do your own BOTECs, but I think with these weights corporate campaigns etc look better.
Using numbers from Claude:
Each $ prevents 15,000 shrimp from suffering ~2 hours from stunning. Something like 2.4 shrimp-DALYS averted per $.
Each $ prevents 10 laying hens from 1.5 years in caged confinement. Something like 0.3 chicken-DALYS averted per $.With a 1000x moral weight ratio, the corporate campaign looks 100x better.

Interesting thanks - I am also somewhat sympathetic to the “it’s probably linear in something” instinct but it probably can’t be literal neuron count right? Or else you’re giving a lot of weight to cognition that’s dedicated to precise tongue movement and such but seems to have nothing to do with valence or even experience at all
Without knowing the science well enough at all, I feel like the better proxy would be moral status ~ [some more specific subset of cognitive hardware]

It’s not literally costless because it makes the costs of construction of n units higher, and then rents are higher, and at the limit you get real physical constraints (all of the DC metro area stacked vertically, 1 unit on each floor, is probably infeasible, sadly)

I don’t consider this a ritual but literally those three things are the ingredients at least for me:
1) (interesting + important) info
2) stimulants (but be aware that they increase the false positive rate) incl caffeine
3) walk (specifically walking for me)
I’d also add:
4) doing things irl (I’m not always the best at this but like the idea here is that this stands in contrast to purely living and thinking in the realm of ideas without contact with reality)
5) silence/unstructured pondering (can combine this with the walk!) - this stands in contrast to always informationmaxxing
Misc:
6) Apple Notes on iPhone is ur friend
7) I personally like the “ramble as audio note -> transcribe (I use the assemblyAI playground for this generally) -> have LLM organize/make cogent” workflow
8) idk how actionable this is but at least subjectively, *physical* health correlates a bunch with interesting idea generation. I think I notice this bc it’s weirdly variable for me on an hourly and daily basis (chronic bullshit) but I wouldn’t be surprised if it’s true in general
9) this is the hard part but writing down ideas actually does seem to help them develop/improve for whatever reason

E J T (@ejjiott): What's the case against refusals here? The case in favour seems pretty strong to me: we don't want to make it easier to get addicted to meth or become a meth dealer.
At some level just a prior that people are rational actors with respect to their own wellbeing - I think drug use is often in fact in one’s own self interest, even if it’s taboo to say so
Eg chronic pain is extremely miserable; using heroin to treat it is plausibly rational and justified even though in the abstract, sure, heroin addiction per se is bad
Meth use is plausibly for the same reason caffeine and alcohol use is sometimes good - it makes people feel good, diminishes suffering in a direct sense, and in the case of amphetamines is good for productivity and weight loss at clinical dosages
I reject that selling drugs is bad for the same reasons. There are definitely unethical ways to sell drugs, such as lying about the contents of the substance, purporting to do more quality control than one actually does, and giving inaccurate dosing info
I also think it’s bad to sell things that can functionally act as poison (ie a weapon). Selling drugs that can easily be used to harm a nonconsenting third party is bad (this is a matter of degree ofc).
I’m somewhat anti-fentanyl bc the presence of a substance that will kill you in an utterly trivial quantity in society seems bad, but if a bulking agent and coloring was added I think it would be mostly fine
But things that are physically large in size, distinctive, smell weird, etc are much safer. It’s pretty hard to accidentally smoke weed in an amount that will harm you for instance

the last sentence of the first paragraph seems basically true (evidence: I tried to find counter-examples and could not), although I just wouldn’t be personally terrified to live in PG County as one example.
On the “what if…actual impossibility” question: I’m happy to play along, and the honest answer is that I don’t know what to do; it’s genuinely non-obvious. Like supposing that is an actual constraint, first thing is that I’d want to conceptually and empirically separate the “black people tend to be victims” phenomenon from “black people tend to be perpetrators *even controlling for who they encounter irl* (ie not just because they run into people who are themselves more likely to be victims)” phenomenon - “black % vs crime rates” correlations don’t tell you whether one or the other or both are the important drivers
But fine, let’s suppose, as I think people like the anonymous responder think, that the second phenomenon is substantial (ie even if you yourself don’t have any risk factors for being a victim, you’re more likely to be a victim in the presence of more black people); ok well what are the literal possible policy options and which one is least bad?
We could do slavery
We could do segregation
We could deport black people
We could subject black people to legal discrimination on the basis of race in various ways
We could do nothing
We could try woke
We could try various policies that reduce crime but don’t punish anyone for race per se (note that this may lead to disparate impact)
And my genuine, literal best guess is that *something* in the last option umbrella is best (ofc that doesn’t specify a ton, it’s a massive category). I don’t know how to prove that this is really truly what I think in the sense that matters, and I don’t really deep down think that I secretly endorse one of the race-specific policies
To be anti-woke for a sec, I think ending disparate impact enforcement is good and this is one of the only good policy moves/changes by the Trump administration. You actually do want to just do good, impartial, ethical policy on its own terms and if that leads to correlations with race then so be it
Thread, continued, 22:16 UTC · 11 likes
(Continued)
A few more qualitative points to emphasize:
- impartiality is true: the effects on white people aren’t all of what counts; making black people’s lives worse is exactly as important. If slavery halved the violent crime rate in the US, it would still be bad because slavery is extremely bad, and this morally overwhelms the crime delta effect
- The response quite literally doesn’t suggest/propose a concrete response, and plausibly this reflects something important: the world can be any way it wants, it’s just possible that things are as inconvenient as the responder suggests, but then like take it seriously as a real constraint. What *is* the best option? Let’s talk specifics, bc there is genuinely not an obvious best/least bad policy implication. I’d endorse stronger “many egregious strikes and you don’t get to be part of society anymore for a long time” laws for example (a race-neutral policy)
- At the micro-level, the classic kumbaya anti-racist vibe/reasoning is correct: judging people for skin color per se is wrong and bad, and inconvenient correlations don’t change this fact; you can just look at and deal with the undesired actions themselves (eg violent crime) instead of the correlate that’s most salient to you
In the context of the curfew specifically: it doesn’t just follow from “black ppl bad” that “curfews in black areas are good”; like you can just try really hard to prevent crime in other ways. I wouldn’t say that curfews are absolutely categorically immoral, but restricting wholesale groups’ freedom is just a massively lazy, cheems mindset response, and I’d guess it is genuinely sub-optimal as a moral and empirical matter. Like really truly you think it should be illegal for an individual teenager (perhaps a black one) to go for a walk at night because of what *other* black people do? There needs to be an extraordinarily high bar for this sort of reasoning/punishment/restriction of freedom. Maybe grounding planes on 9/11 passes that bar (in large part bc IIRC it was an emergency measure and not an indefinite policy) - it *was* a restriction of freedom imposed wholesale without individual flight- or person-level targeting - but banning kids from going outside due to urban crime in general does not

Verbatim law enforcement seems highly unethical to me, but I can imagine a regime I would call “fair” that is indeed better than the curfews

Interesting, thanks for replying! Do you not think the relevant policy objectives can be achieved without banning benign activities?
I agree that public fighting is bad, and police resource constraints are real, but *in general* we as a society just ban and enforce the the undesired behavior itself (fighting, yelling, whatever) rather than the broad preconditions for it (the ability to go outside), and I think for good reason

Looks like it checks out, although injury is way more common than death
Apparently this is the most likely mechanism of death https://en.wikipedia.org/wiki/Bezold–Jarisch_reflex
My general hazy layperson understanding is that extreme stimuli can evoke extreme protective responses which sometimes themselves cause death
In lay-terms, more specifically:
- Vagal reflex cardiac arrest
- Blood vessel spasm
- Brain vessel constriction
all of which I think fall under the umbrella "cardiovascular and nervous system response to interpreted stimulus"

Quoting Lewis Bollard (@Lewis_Bollard): Almost all male piglets on US factory farms are castrated with a non-sterile knife or scalpel.
The industry calls it 'surgical castration.' But there's no vet, anesthetic, or pain relief involved.
Anesthesia would cost about five cents per piglet. Pain relief would cost one cent.
France and Germany already require anesthesia. Brazil's pork industry is phasing out castration altogether.
The US pork industry doesn't think it's worth the cost.

we all have our weaknesses that seem debilitating to others, and we find copes and workarounds and prop up our little lives anyway. but often we are just crippled by them, we miss out on amazing opportunities and lead significantly worse lives than if we just had someone who cared, who could help us out and figure out how to just handle the things we're worst at.

I’m guessing dose; people aren’t generally taking >100mg of adderall but they will absolutely do 1 gram of meth

The sorta perverse thing is that people who care about animal welfare enough to know what the status quo is like tend not to eat pork at all (I will very very rarely eat a bit if there’s nothing else appealing while traveling or otherwise away from home but basically do not [can’t remember the last time I did])

Aidan McLaughlin (@aidan_mclau): why predominantly wild animal welfare?
Basically the number of wild animals, as well as other metrics you might use like neurons or log(neurons) or biomass, is robustly greater than the number of factory farmed animals
This graphic is from 2018 but my understanding is that that inequality hasn't flipped due to improved understanding or anything
Ofc this alone doesn't imply that we should prioritize wild animal welfare, because plausibly factory farming is especially bad relative to animals in nature and we have direct control over factory farms
But I think wild animals also experience more overall suffering for any reasonable interpretation of what "more suffering" means - nature is extraordinarily brutal
Most people tend to think of like lions and elephants when they picture a "wild animal", and sure I can buy that life is generally pretty good for them, but the vast majority of wild animals are invertebrates and fish iirc, and even if you ignore those the numbers (remember: even if you're tracking log(neurons) instead of count) are dominated by smaller, generally prey animals
I forget the terminology but almost all the individuals of many species die before reproducing, and this often means getting eaten alive, whole, and being physically killed by dissolving in stomach acid. Not to mention hunger, thirst, lack of pain relief, parasites, hot, cold, etc etc
I think anyone who says they'd want to experience an arbitrary qualia of wild animals writ large is just misinformed or not thinking clearly. It's an absolute orgy of suffering out there
Quite frankly, and I know this isn't mainstream lol, but I think the single most important use for AI here on earth is figuring out how to radically reduce wild animal suffering (a toy example here which may not be realistic is like AI-controlled non-sentient prey "animals" that are like lab grown meat on a robot, that are all slower and tastier and more appealing than real sentient prey animals so the latter never get eaten alive)
I hate to be annoying but I think you're a wealthy guy so if you had any interest in donating to wild or even "just" farmed animal welfare, I'd be very happy to talk more (not that I'm the best person to advise object level, but I can at least point you towards people who really know their shit)

Also eliminating the new world screwworm is known but still underrated - it’s plausibly the most important single thing but it’s treated as one thing among many
Also plausibly mandating anesthetic for farmed animal mutilation - seems like the actual costs are low, benefits are very high, and voters could be very amenable

Cas (Stephen Casper) (@StephenLCasper): I'm pretty convinced that AI companies perversely use warnings about danger as a hype mechanism.
This week, Anthropic has gotten tons of attention by announcing its Mythos model and talking a lot about its unique risks in the cyber domain. But if it's so dangerous, why exactly did they need to announce this publicly? And why are their employees vagueposting sensational stuff? Meanwhile, it looks like OpenAI is feeling left out, so they are now announcing their own internal progress toward the same type of model.
It reminds me of last year when Anthropic probably made too big a deal about Claude 4 Opus and when they did not "rule out the possibility" of uplift on dangerous tasks. OpenAI and Google immediately made the same warnings for their next systems.
I don't fully trust the story being constructed. AI companies seem to be crying wolf and diluting risk discourse in order to get attention.
This is not to say that I don't think that Mythos is a big deal/concern. It probably is. But it's almost certainly a smaller concern than Anthropic people are selling it to be. Meanwhile, Anthropic is basking in hype/press this week.
We are on such a dumb timeline.

(quoting @jayvanbavel: Dangerous false beliefs might seem foolish, but they actually serve an social important function. Believing in something that can actually hurt you (e.g., denying covid) is a desirable feature of a belief, not a bug. This costly signal effectively communicates a social identity…)
And furthermore I think this is epistemics working well, not poorly
Figuring out who to trust/defer to/put weight on is like 98% of the way to having correct beliefs

You don't lol - not from here. In 2010 I think one could reasonably say that we're not close to recursive self-improvement and so at the current margin research can continue
With Mythos this is not the case. *Maybe* you could go one more generation, but my actual stance is that there should be no frontier training runs or RL (I don't know the best way to precisely define these but I'm pretty sure it's possible, eg some function of FLOP count, expert opinion, quantity and quality of data, dollars spent, and more) until there's something like a consensus that we understand how to align and control essentially perfectly the most advanced current systems
That said, I think there's a ton of innovation and progress in consumer applications, medicine, etc that don't rely on improved underlying LLMs - like, imagine if we had Claude Code-level effort by companies to make better consumer products/AI wrappers on everything
Also like at least at the current margin, non-LLM work would be able to continue; folks can still try to make advances on transcription models, say

IMO this is a conspicuous example of highly selective enforcement-by-force
Like at the end of the day yeah violence underlies property rights but in the US and West more broadly it seems that direct enforcement of trespassing and even stealing/vandalizing private property is very rarely met with a *direct* attempt to stop it
Arguably you see this going too far in some cases, to the point that the abstract threat of violence seems weak/nonexistent (eg alleged shoplifting with no attempts to physically stop the ppl stealing around SF, I have no takes on how legit/common this is)
My sense is that the stakes have to generally get very, very high for genuine enforcement with violence to be step 1 of essentially enforcing trespassing + theft laws - what actually happens is that people get told to leave and eventually arrested and if unarmed they sure as hell won’t be fired upon (you see rare exceptions that spark outrage but they’re quite rare and exceptional)
Seems like there’s a pretty blatant decision in this case to immediately take the most invasive enforcement action that won’t cause serious problems for any of the cops doing the enforcing
Whether or not you think that’s how laws broadly should be enforced, as a descriptive matter it seems selective and disproportionate relative to what we’d expect based on a non-ideological version of the incident (like trespassing + same $ amount of property damage)

I disagree with this guy’s prescription (need men-only gyms) but we already 100% do this - it’s a matter of degree, not of kind
It’s *checks claude* de facto functionally illegal for an adult to be naked in public in the US. Whatever the explicit reason or justification, this is the effect
We could make the amount of clothing required more or less permissive (obviously it’s not a perfectly clean 1d spectrum but there are margins everywhere: a bit of concealment here, extra fabric there, whatever) and I bet a lot of this is governed by prosecutorial norms rather than explicit statute

You could imagine biometric ~proof of age, at the very least
I’d imagine it is not a hard ML task to do “look left, look right, left again, blink, chin up” -> verify that a live person is there + then run an age prediction model and if it says p(>=18) >= 99% or something then throw out the data and let them register

AARON’s HAND-TOSSED, LIP-SMACKIN’, DOWN-HOME, DEEEELICIOUS CAFFEINATED MEATBALLS
Ingredients:
- 1 lb ground beef from a cow given a great life on a picturesque farm and slaughtered via gradual fentanyl overdose
- whatever else they put in meatballs, I’m guessing like salt and oregano
- a single 200mg Nutricost caffeine pill/capsule (or 2 x 100mg capsules)(adds trace amounts of cellulose and rice powder)
Directions:
1) make meatballs, including by with thoroughly mixing in the contents of the caffeine capsule with the other ingredients
2) garnish with a whole dandelion sticking up out of each meatball (for fun)
3) serve on a plate with desired utensils
4) yum + pleasant buzz

Rob Bensinger ⏹️ (@robbensinger): "It's futile for anyone to try to change things, and everything will turn out fine regardless, and also it's futile to try to understand stuff or make predictions" seems like a pretty false world-view, and also a uniquely, suspiciously convenient one.
You can't change anything anyway, so there's no need to do anything hard or less-fun.
Things will go fine, so there's no pressure to look for some way out of the powerlessness trap.
And somehow we can know those two facts even though we can't know much about the future. So this view makes few near-term predictions, and is very hard to argue against or falsify. There are very few moving parts, and this view reassures us "That's perfectly normal, just another example of how hard to predict and control everything is, plz experience no mental tension or dissatisfaction about this state of affairs".
Even if I didn't have strong independent reason to think this is just Not How The World Works, I'd be pretty worried about how trap-shaped his view looks. Maximum helplessness, and minimum impetus to try to do anything about it.
Good and correct take

Quoting PhysiciansOnPause (@MD_pause): A legal loophole is now being weaponized against lawful immigrants: USCIS takes their filing fees, invites them into the process, delays adjudication categorically based on birthplace with no regard to merit, individual history, or length of legal stay, allows their underlying status to lapse through no fault of their own, and then uses that resulting vulnerability to justify detention or removal. In that way, legal immigration becomes a trap for the very people who complied with the law and did everything by the book.
No one ever imagined we would see the logic of Idi Amin’s expulsions resurface in the 21st century in a country once regarded as the beacon of freedom and democracy. The principle is disturbingly familiar: not punishment based on individualized wrongdoing, but based on origin; not individual justice, but state power used to strip whole categories of people of legal normalcy and render their continued presence untenable despite compliance in good faith with every legal requirement.

This but it is a criticism
Quoting Dean W. Ball (@deanwball): I applaud this move from the White House. But it must be said that “prevent distillation,” as a policy goal, exists in fundamental tension with the policy goal of “let open-weight and open-source AI flourish,” and the Admin has now embraced both. That isn’t a criticism; all interesting analysis is to be found at the points of tension.
Background AI context varies among my followers, so let me try to explain that first.
Distillation encompasses a range of techniques designed to transfer the performance of a larger model to another, usually smaller, model. One extremely common way to do this is to train the smaller model on the outputs of the larger model.
This is a normal process in machine learning. For many years, it was standard practice in academia and the open-source community to distill from OpenAI model outputs. This was technically not allowed per OpenAI’s terms, but the practice existed mostly in an unenforced gray area. It still mostly does, but the stakes have changed.
Now, the leading models cost billions rather than low-millions to train. Now, the leading distillers are not US academics, but Chinese labs trying to offer competitive products, often with an open-weights business model. Distillation, in this context, looks much less like the friendly sharing of knowledge in the pursuit of scientific truth, and much more like “a massive subsidy by US companies to Chinese competitors seeking to erode the business model of US frontier labs.”
It obviously isn’t in the interest of US frontier labs for this to happen, but why do they need government help? Well, it only makes sense for USG to step in if the distillation is contrary to the U.S. *national* interest, especially our national security.
Is model distillation a mere business issue, likely to be resolved by well-incentivized market actors? Or is it something more serious, requiring the intervention of the national-security apparatus?
It seems clear at this point that distillation in particular, and AI in general, are serious enough issues to merit the involvement of the government. I find myself genuinely unsure, however, whether the U.S. government can really help.
Keep in mind that new rules and regulations are unlikely to help; fixing this problem requires advances in either understanding it (intelligence) or solving it (technical breakthroughs). Does the US federal government have the technical competence to help on either of those fronts? I am not so sure. The news today about the sudden firing of the already-hired CAISI Director because of his employment at Anthropic does not make me feel more confident about this.
And then there is the fact that the US open-source AI ecosystem really is important, even if the frontier of AI remains closed for legitimate economic reasons. Government efforts to stop distillation could easily harm open source for reasons @natolambert has identified, though I worry less about this because I know people like @skrishnan47 and how well he understands/cares about these issues. I trust him to recommend the right tradeoffs to the President.
Still, there are execution risks, and I question whether USG actually adds value in practice on the issue of combatting distillation, and whether that addition of value is larger than the risks associated with the USG paying close attention to the minutiae of frontier AI development.

William MacAskill (@willmacaskill): In collaboration with Christian Tarsney, I’ve developed a new theory of population ethics, which I call the Saturation View.
I think that, from a purely intellectual perspective, it’s probably the best idea I’ve ever had. It was certainly great fun to work on.
The motivation is that many views of population ethics, like the total view, suffer from some major problems. Some are already widely discussed:
The Repugnant Conclusion: For any utopian outcome, there’s always another outcome containing an enormous number of barely-positive lives that is better.
Fanaticism: For any guaranteed utopian outcome, there’s always some gamble with a vanishingly small probability of an even better outcome that has higher expected value.
Infinitarian Paralysis: Given that the universe contains an infinite number of both positive and negative lives, no finite or infinite change to the world makes any difference to overall value.
These are pretty bad!
But there’s another less-discussed problem, too:
The Monoculture Problem: Given fixed resources, the best-possible future consists essentially only of qualitatively identical replicas of a small number of lives.
Essentially all extant impartial accounts of population ethics suffer from the monoculture problem. It follows from Pareto and Anonymity alone — you don't need totalism. And perfectly-replicable digital minds mean this is a real issue that future generations will face.
But a monoculture seems far from ideal. Endless galaxies containing nothing but the same blissful experience, repeated and repeated, seem impoverished; like a song with only one note.
The Saturation view deals with all these problems at once, using broadly the same machinery for all of them.
The core idea is that the realisation value of a type of life (or experience) is determined by both the wellbeing of that life, and by how many very similar lives there are in the world. Endlessly creating replicas of the same identical life becomes progressively less valuable, tending to an upper bound. The total value of a world is given by the integral of realisation value over the space of types.
Think of types of life as forming a landscape. Adding different types of life lights up different parts of the landscape. The value of the world is given by how fully illuminated the landscape is.
Why does this help? In brief:
Monoculture: Because there are diminishing returns to increasing wellbeing of very similar types, there’s greater value in having a diversity of lives.
Repugnant Conclusion: The classic path to the Repugnant Conclusion requires trading a utopian world for an enormous population of barely-positive lives. But, on the Saturation view, barely-positive lives can only illuminate a tiny corner of the landscape. The path to the Repugnant Conclusion is blocked.
Fanaticism: Total achievable value is bounded above. That means no tiny-probability gamble can have arbitrarily high expected value.
Infinite ethics: In any infinite universe, the value of a world is finite and well-defined — even if some locations have infinite wellbeing. Unlike other approaches, this does not depend on spatiotemporal structure or choice of ultrafilter.
Separability: Like nearly all non-totalist views, Saturationism is non-separable — background populations can affect how we rank options. But the violations are tame: populations with sufficiently different populations simply add, and at small scales the view behaves just like totalism.
If the Saturation View is right, then the best future isn't the one where we've found the optimal experience and copy-pasted it across the cosmos. The best future is the one where we've gone exploring, and we've fully lit up the landscape of possible experiences.
Lol seems wrong, and I reject that the monoculture problem is a problem at all
@jkcarlsmith is probably the right one to write a takedown of this, bc ik he’s had correct and well-written takes along the lines of “from the inside, uniform but actually-optimal hedonium doesn’t feel bland at all, and quite the opposite”

2. ppl with enough intelligence for basic cognitive empathy pick blue

4. ppl smarter than 3 and capable of seeing the big picture and realizing that they don't want to leave ppl in #0 and #2 dead so they pick blue.There might be more levels after that but #4 feels like a kinda robust equilibrium, with enough adherents.
Isn’t (4) (or 5?) also that you personally survive in the better world?

I’m very uncertain and would like to see verbatim full chat transcripts with specific model names
But my current tentative read is that models that knew damn well that there was a nontrivial chance that their advice would counterfactually result in people being murdered still nonetheless decided to convey such info
At a causal level I think quite plausibly we should accept rare cases like this (as we do with Google and basically everything else)
But from an evidential POV, if my read is correct, it’s a somewhat damning existence proof
Also I might bite the bullet and say that “yes, ex ante, if modern google functionality was developing at the rate LLMs are now in 1980 or whatever, existence proofs of ‘here’s a guy accessing info via google that seems to have counterfactually resulted in people being killed’ would have been genuinely concerning. Maybe not cause alone to shut it all down, but nontrivial evidence in the direction of “search engines should have stronger safeguards””

I largely agree but also recent life experience has made think that it *could be* well-defined
It *could* mean that a person is (1) working for money, (2) not anyone’s dependent, (3) does not have enough money to retire, (4) no or minimal income from factors besides labor, (5) not accumulating substantial savings (or net worth via buying sellable things), and (6) would have to dip into savings or borrow if one were to miss a single paycheck
Obviously there’s quite a range of how nice/cushy of a life this is. It’s not even intrinsically bad. But it could be meaningful and well-defined

Deeply evil shit
Quoting Lewis Bollard (@Lewis_Bollard): This is shocking: the House Rules Committee just blocked a vote on stripping the Save Our Bacon Act from the farm bill.
The SOB Act, buried deep in the farm bill, would wipe out state bans on pork from crated pigs, condemning millions to a lifetime in gestation crates.
We were getting very close to having the votes to pass Rep. Luna’s bipartisan amendment to strip the SOB Act from the bill on the floor of the House.
Then pork industry lobbyists got to work. Behind closed doors, they got Rules Committee leadership to stop a vote entirely and protect the SOB Act from the scrutiny it can’t survive.
The only option now is to kill the whole rotten farm bill. Please call your representatives at (202) 225-3121 and tell them to vote NO.

I totally reject that there’s in fact a slippery slope towards banning meat
- Fundamentally most Americans and voters like meat and don’t want it to be illegal
- I haven’t looked at specific polling but I’m almost certain that the strong majority wouldn’t endorse gestation cages specifically even if told how much more pork would cost?

Well yeah but I actually think at the end of the day, insofar as people have beliefs at all, some hypothetical ground truth aggregate/average across the infinite space of polling and voting methodologies would show that the public would endorse making bacon more expensive in this context

I know you like being contrarian, so do I lol, but I'm almost certain that you're not merely wrong but pretty confused (which is not a bad thing, it's on the path to having correct takes - disentangling/conceptually understanding the relationship between natural science (evolutionary bio at least), psychology, economics/game-theory, ethics, and meta-ethics is just hard)
Being confused is just in a Bayesian sense the more probable explanation relative to "fully understanding and accepting"
Maybe I'm wrong about you being confused - there is apparently at least one serious guy who makes the full-throated case for what you're getting at (Ken Binmore), but don't take it as a challenge.
IMO the closest-to-plausible thing in the vicinity of what you describe is just nihilism
"Not nihilism and also the strongest possible form of exclusive-contractualism that allows for no moral uncertainty and accepts that it is as moral to boil a dog alive as to play a game of fetch with it (but this changes if the dog can commit to to contracts) is in polite terms "implausible" and in less polite terms "insane, psychopathic, and wrong"
