I’m glad you agree! For the sake of controversy, I’ll add that I’m not entirely sure that scenario is out of consideration from an EV point of view, firstly because the exhaust will have a lot of energy and I’m not sure what will happen to it, and secondly because I’m open to a “diminishing returns” model of population ethics where the computational capacity furloughed does not have an overwhelmingly higher value.
On singletons, I think the distinction between “single agent” and “multiple agents” is more of a difference in how we imagine a system than an actual difference. Human civilization is divided into minds with a high level of communication and coordination within each mind and a significantly lower level between minds. This pattern is an accident of evolutionary history and if technological progress continues I doubt it will remain in the distant future, but I also don’t think there will be perfect communication and coordination between the parts of a future civilization either. Even within a single human mind the communication and coordination is imperfect.
I guess. I don’t like the concept of a singleton. I prefer to think that by describing a specific failure mode this gives a more precise model for exactly what kind of coordination is needed to prevent it. Also, we definitely shouldn’t assume a coordinated colonization will follow the Armstrong-Sandberg method. I’m also motivated by a “lamppost approach” to prediction: This model of the future has a lot of details that I think could be worked out to a great deal of mathematical precision, which I think makes it a good case study. Finally, if the necessary kind coordination is rare then even if it’s not worth it from an EV view to plan for our civilization to end up like this we should still anticipate alien civilizations to look like this.
It’s true that making use of resources while matching the probe’s speed requires a huge expenditure of energy, by the transformation law of energy-momentum if for no other reason. If the remaining energy is insufficient then the probe won’t be able to go any faster. Even if there’s no more efficient way to extract resources than full deceleration/re-acceleration I expect this could be done infrequently enough that the probe still maintains an average speed of >0.9c. In that case the main competitive pressure among probes would be minimizing the number of stop-overs.
The highest speed considered in the Armstrong/Sanders paper is 0.99c, which is high enough for my qualitative picture to be relevant. Re-skimming the paper, I don’t see an explicitly stated reason why the limit it there, although I note that any higher speed won’t affect their conclusion about the Fermi paradox and potential past colonizer visible from Earth. The most significant technological reasons for this limit I see them address are the energy costs of deceleration and damage from collisions with dust particles, and neither seems to entirely exclude faster speeds.
Yes, at such high speeds optimizing lateral motion becomes very important and the locations of concentrated sources of energy can affect the geometry of the expansion frontier. For a typical target I’m not sure if the optimal route would involve swerving to a star or galaxy or whether the interstellar dust and dark matter in the direct path would be sufficient. For any particular route I expect a probe to compete with other probes taking a similar route so there will still be competitive pressure to optimize speed over 0.99c if technologically feasible.
A lot of what I’m saying remains the same if the maximal technologically achievable speed is subrelativistic. In other ways such a picture would be different, and in particular the coordination problems would be substantially easier if there is time for substantial two-way communication between all the probes and all the colonized areas.
Again, I see a lot of potential follow-up work in precisely delineating how different assumptions on what is technologically possible affect my picture.
[Crosspost] Relativistic Colonization
historical cases are earlier than would be relevant directly
Practically all previous pandemics were far enough back in history that their applicability is unclear. I think it’s unfair to discount your example because of that, because every other positive or negative example can be discounted the same way.
I’ve just examined the two Wikipedia articles you link to and I don’t think this is an independent discovery. The race between Einstein and Hilbert was for finding the Einstein field equations which put general relativity in a finalized form. However, the original impetus for developing general relativity was Einstein’s proposed Equivalence Principle in 1907, and in 1913 he and Grossman published the proposal that it would involve spacetime being curved (with a pseudo-Riemannian metric). Certainly after 1913 general relativity was inevitable, perhaps it was inevitable after 1907, but it still all depended on Einstein’s first ideas.
That’s a far cry from saying that these idea wouldn’t have been discovered until the 1970s, which I’m basing mainly on hearsay and I confess is much more dubious.
I don’t recall the source, but I remember hearing from a physicist that if Einstein hadn’t discovered the theory of special relativity it would surely have been discovered by other scientists at the time, but if he hadn’t discovered the theory of general relativity it wouldn’t have been discovered until the 1970s. More specifically, general relativity has an approximation known as linearized gravity which suffices to explain most of the experimental anomalies of Newtonian gravity but doesn’t contain the concept that spacetime is curved, and that could have been discovered instead.
I’m puzzled by Mallatt’s response to the last question about consciousness in computer systems. It appears to me like he and Feinberg are applying a double-standard when judging the consciousness of computer programs. I don’t know what he has in mind when he talks about the enormous complexity of conscious, but based on other parts of the interview we can see some of the diagnostic criteria Mallatt uses to judge consciousness in practice. These include behavioral tests such as going back to places an animal saw food before, tending wounds, and hiding when injured, as well as structural tests such as a multiple levels of intermediate processing from the sensory input to motor output. Existing AIs already pass the structural test I listed, and I believe they could pass the behavior tests with a simple virtual environment and reward function. I don’t see a principled way of including the simplest types of animal conscious while any form of computer consciousness.
On the second paragraph, making your point succinctly is a valuable skill that is also important for anti-debates. A key part of this skill is understanding which parts of your argument are crucial for your conclusion and which merit less attention. The bias towards quick arguments and the bandwagon effect also exist in natural conversation and I’m not sure if it’s any worse in competitive debating. I have little experience with competitive debating so I cannot make the comparison and am just arguing from how this should work in principle.
On the other hand, in natural conversation you want to minimize use both of the audiences’ time and cognitive resources, whereas competitive debate weighs more heavily in minimizing time, which distorts how people learn succinctness from it. Also, the time constraint in competitive debate might be much more severe than the mental resource constraint in the most productive natural conversations, and so many important skills that are only applied in long-form conversation are not practiced at all.
You should consider whether something has gone terribly wrong if your method for preventing s-risks is to simulate individuals suffering intensely in huge quantities.
A particular word choice that put me at unease is calling “dating a non-EA” “dangerous” without qualifying this word properly. It is more precise to say that something is “good” or “bad” for a particular purpose than to just call it “good” or “bad”; just the same with “dangerous”. If you call something “dangerous” without qualification or other context, this leaves an implicit assumption that the underlying purpose is universal and unquestioned, or almost so, in the community you’re speaking to. In many cases it’s fine to assume EA values in these sorts of statements—this is an EA forum, after all. Doing so for statements about value drift appears to support the norm that people here should want to stay with EA values forever, a norm which I oppose.
It seems to me like you’re in favor of unilateral talent trading, that is, that someone should work on a cause he thinks isn’t critical but he has a comparative advantage there, because he believes that this will induce other people to work on his preferred causes. I disagree with this. When someone works on a cause, this also increases the amount of attention and perceived value it is given in the EA community as a whole. As such I expect the primary effect of unilateral talent trading would be to increase the cliquishness of the EA community—people working on what’s popular in the EA community rather than what’s right. Also, what’s commonly considered as EA priorities could differ significantly from the actual average opinion, and unilateral trading would unrightly shift the latter in the direction of the former, especially as the former is more easily gamed by advertising etc.. On the whole, I discourage working on a cause you don’t think is important unless you are confident this won’t decrease the total amount of attention given to your preferred cause. That is, only accept explicit bilateral trades with favorable terms.
On this very website, clicking the link “New to Effective Altruism?” and a little browsing quickly leads to recommendations to give to EA funds. If EA funds really is intended to be a high-trust option, CEA should change that recommendation.
I haven’t responded to you for so long firstly because I felt like we got to the point in the discussion where it’s difficult to get across anything new and I wanted to be attentive to what I say, and then because after a while without writing anything I became disinclined from continuing. The conversation may close soon.
Some quick points:
My whole point in my previous comment is that the conceptual structure of physics is not what you make it out to be, and so your analogy to physics is invalid. If you want to say that my arguments against consciousness apply equally well to physics you will need to explain the analogy.
My views on consciousness that I mentioned earlier but did not elaborate on are becoming more relevant. It would be a good idea for me to explain them in more detail.
I read your linked piece on quantifying bliss and I am unimpressed. I concur with the last paragraph of this comment.
Do you think we should move the conversation to private messages? I don’t want to clutter a discussion thread that’s mostly on a different topic, and I’m not sure whether the average reader of the comments benefits or is distracted by long conversations on a narrow subtopic.
Your comment appears to be just reframing the point I just made in your own words, and then affirming that you believe that the notion of qualia generalizes to all possible arrangements of matter. This doesn’t answer the question, why do you believe this?
By the way, although there is no evidence for this, it is commonly speculated by physicists that the laws of physics allow multiple metastable vacuum states, and the observable universe only occupies one such vacuum, and near different vacua there different fields and forces. If this is true then the electromagnetic field and other parts of the Standard Model are not much different from my earlier example of the alignment of an ice crystal. One reason this view is considered plausible is simply the fact that it’s possible: It’s not considered so unusual for a quantum field theory to have multiple vacuum states, and if the entire observable universe is close to one vacuum then none of our experiments give us any evidence on what other vacuum states are like or whether they exist.
This example is meant to illustrate a broader point: I think that making a binary distinction between contextual concepts and universal concepts is oversimplified. Rather, here’s how I would put it: Many phenomena generalize beyond the context in which they were originally observed. Taking advantage of this, physicists deliberate seek out the phenomena that generalize as far as possible, and over history broadened their grasp very far. Nonetheless, they avoid thinking about any concept as “universal”, and often when they do think a concept generalizes they have a specific explanation for why it should, while if there’s a clear alternative to the concept generalizing they keep an open mind.
So again: Why do you think that qualia and emotional valence generalize to all possible arrangements of matter?
It wasn’t clear to me from your comment, but based on your link I am presuming that by “crisp” you mean “amenable to generalizable scientific theories” (rather than “ontologically basic”). I was using “pleasure/pain” as a catch-all term and would not mind substituting “emotional valence”.
It’s worth emphasizing that just because a particular feature is crisp does not imply that it generalizes to any particular domain in any particular way. For example, a single ice crystalline has a set of directions in which the molecular bonds are oriented which is the same throughout the crystal, and this surely qualifies as a “crisp” feature. Nonetheless, when the ice melts, this feature becomes undefined—no direction is distinguished from any other direction in water. When figuring out whether a concept from one domain extends to a new domain, to posit that there’s a crisp theory describing the concept does not answer this question without any information on what that theory looks like.
So even if there existed a theory describing qualia and emotional valence as it exists on Earth, it need not extend to being able to describe every physically possible arrangement of matter, and I see no reason to expect it to. Since a far future civilization will be likely to approach the physical limits of matter in many ways, we should not assume that it is not one such arrangement of matter where the notion of qualia is inapplicable.
Thanks for the link. I didn’t think to look at what other posts you have published and now I understand your position better.
As I now see it, there two critical questions for distinguishing the different positions on the table:
Does our intuitive notion of pleasure/suffering have objective precisely defined fundamental concept underlying it?
In practice, is it a useful approach to look for computational structures exhibiting pleasure/suffering in the distant future as a means to judge possible outcomes?
Brian Tomasik answers these questions “No/Yes”, and a supporter of the Sentience Institute would probably answer “Yes” to the second question. Your answers are “Yes/No”, and so you prefer to work on finding the underlying theory for pleasure/suffering. My answers are “No/No”, and am at a loss.
I see two reasons why a person might think that pleasure/pain of conscious entities is a solid enough concept to answer “Yes” to either of these questions (not counting conservative opinions over what futures are possible for question 2). The first is a confusion caused by subtle implicit assumptions in the way we talk about consciousness, which makes a sort of conscious experience from which includes in it pleasure and pain seem more ontologically basic than it really is. I won’t elaborate on this in this comment, but for now you can round me as an eliminativist.
The second is what I was calling “a sort wishful thinking” in argument #4: These people have moral intuitions that tell them to care about others’ pleasure and pain, which implies not fooling themselves about how much pleasure and pain others experience. On the other hand, there are many situations where their intuition does not give them a clear answer, but also tells them that picking an answer arbitrarily is like fooling themselves. They resolve this tension by telling themselves, “there is a ‘correct answer’ to this dilemma, but I don’t know what it is. I should act to best approximate this ‘correct answer’ with the information I have.” People then treat these “correct answers” like other things they are ignorant about, and in particular imagine that a scientific theory might be able to answer these questions in the same way science answered other things we used to be ignorant about.
However, this expectation infers something external, the existence of a certain kind of scientific theory, from evidence that is internal, their own cognitive tensions. This seems fallacious to me.
Thanks for reminding me that I was implicitly assuming computationalism. Nonetheless, I don’t think physicalism substantially affects the situation. My arguments #2 and #4 stand unaffected; you have not backed up your claim that qualia is a natural kind under physicalism. While it’s true that physicalism gives clear answers for the value of two identical systems or a system simulated with homomorphic encryption, it may still be possible to have quantum computations involving physically instantiated conscious beings, by isolating the physical environment of this being and running the CPT reversal of this physical system after an output has been extracted to maintain coherence. Finally, physicalism adds its own questions, namely, given a bunch of physical systems that all appear to have behavior that appears to be conscious, which ones are actually conscious and which are not. If I understood you correctly, physicalism as a statement about consciousness is primary a negative statement, “the computational behavior of a system is not sufficient to determine what sort of conscious activity occurs there”, which doesn’t by itself tell you what sort of conscious activity occurs.
I reached this article through a link that already revealed that it was about self-care but didn’t notice the “self-care” in the title, and I expected the rhetoric to be a bait-and-switch that starts by talking about how aiming for the minimum in directly impact-related things is bad and then switches to arguing that the same reasoning applies to self-care.
