In which types of cells the most of transpasone damage happens? In stem cells? Other types of cells are recycled quickly. The same question arises about ROS. 

Also, how your theory explains difference in life expectancy between different species?

Comment by avturchin on Russian x-risks newsletter spring 21 · 2021-06-03T13:02:04.447Z · LW · GW

A person who works on other vaccine, told me that Sputnik (and other similar vaccines based on vectors) generate like 2000 random antibodies and there is a chance that some of them will turn autoimmune and cause, say, encephalitis. Other types of vaccines generate antibody not the whole vector but only to spike protein, like 30 different ones, and there are less chances of autoimmune reaction.

But most people do not know these considerations. However, they had observed how government manipulated data during elections and Olympic games and are sure that they will lie again; or they believe in "Bill Gates' chip". 

Comment by avturchin on Is driving worth the risk? · 2021-05-11T22:13:52.403Z · LW · GW

BTW, my personal choice is Uber Black.: I don't have car and I delegate driving to special trained person. Every time I take Comfort, I regret, as I have near-miss accidents. It is relatively cheap in my area.

I have two-three people who I knew and who died in accidents: all of the were "reckless pedestrians". It supports you point about the ability of pedestrians to manage risks.

Can't find a link on statistic of accidents by car types 

Comment by avturchin on Is driving worth the risk? · 2021-05-11T11:40:54.076Z · LW · GW

Around half deaths from car accidents are pedestrians (may be less in US). By choosing not to drive, you increase the time of walking and your chances of being hit by other person's car. 

Other means of transport like cycling or buses are also risky. 

Sitting home is even more dangerous as there are risks of depression and being overweight. 

Finally, some cars are like two-three orders safer than others, if we look at the number of reported deaths per billion km driving. I saw once that Toyota Prius had 1 death for 1 billion km, but Kia Rio was only 1 for 10 millions. Also, there are special racing cars which are reinforced from inside and can roll safely

Wearing helmet inside a car is also useful. 

Waiting few years for self-driving Tesla Cybertrack may be an option.

Placebo could work because it has some evolutionary fitness, like the ability to stop pain in case of the need of activity. 

Benevolent simulators could create an upper limit of subjectively perceived pain, like turning off qualia but continue screaming. This will be unobservable scientifically. 

Comment by avturchin on Simulation theology: practical aspect. · 2021-05-05T12:22:50.055Z · LW · GW

The ability to change probability of future events in favor of your wishes is not a proof of simulation, because there is an non-simulation alternative where it is also possible. 

Imagine that natural selection in quantum multiverse worked in the direction that helped to survive beings which are capable to influence probabilities in favorable way. Even a slightest ability to affect probabilities will give an enormous increase of measure, so the anthropics favor you to be in such world, and such anthropic shift may be even stronger than the shift in the simulation direction. 

In that case, it perfectly reasonable to expect that your wishes (in your subjective timeline) will have a higher probability to be fulfilled.  A technological example of such probability shift was discussed in The Anthropic Trilemma by EY.

Comment by avturchin on What weird beliefs do you have? · 2021-05-03T23:39:30.480Z · LW · GW

Doomsday argument and quantum immortality are both true, and it means that I will be the only survivor of a global catastrophe. Moreover, it will be in a simulation.

Both DA and QI could be tested in other fields. DA was tested to predict other things besides the end of the world by Gott. QI is anthropic principle applied to the future. 
Aranyosi claimed that DA and Simulation argument cancel each other, but actually they support each other: I live (or will live because of QI) in a simulation which simulates a doomsday event with one survivor.

We could test Doomsday argument on other things, like Gott has tested it on broadway shows. For example, I can predict that your birthday is not 1 of January with high confidence. It is also true for my birthday date, which is randomly selected from all dates of the year. So despite my "who I am" axiom, my external properties are distributed randomly.

Comment by avturchin on "Who I am" is an axiom. · 2021-04-26T11:14:44.781Z · LW · GW

All that we know about x-risks tells us that Doomsday argument should be true, or at least very probable. So we can't use its apparent falsity as an argument that some form of anthropic reasoning is false.

Comment by avturchin on Is there anything that can stop AGI development in the near term? · 2021-04-24T13:10:33.677Z · LW · GW

Not any nuclear war will work. If it will be a nuclear exchange between major superpowers, but many well developed countries survive, it will not slow down AI significantly. Even such war may accelerate AI as it will be seen as a new protective weapon.

Only anti-AI nuclear war which will target chip fabs, data centeres, electricity sources and brain tanks + global economy in general may be "effective" in halting AI development. I don't endorse it, as the extinction probability here is close to AI's extinction probability.

Glitches may appear if simulators use very simple world-modelling systems, like 2D surface modelling instead of 3D space modelling, or simple neural nets to generate realistic images like our GANs.

I now have covid after being vaccinated 3 months ago by Russian Sputnik-V vaccine. For now, it is mild: one day of 38 C, 3 days of 37.5C, only upper level infection, no cough. I lost smell, but it is is slowly returning. Oxygen at my normal level.

Comment by avturchin on On Falsifying the Simulation Hypothesis (or Embracing its Predictions) · 2021-04-12T10:59:15.284Z · LW · GW

I agree that simpler simulations are more probable. As a result the cheapest and one-observer-cenetered simulation are the most numerous. But cheapest simulation will have the highest probability of glitches. Thus the main observable property of  living in simulation is higher probability to observer miracles.

Here you have neurons and order of their connection. This order is a graph and could be described as one long number. Mind states appear as a brain moves from one state to another, and here it will be transition from one number to another.  

This is exactly what Muller wrote in his article, which you linked: you need just numbers and a law based on Kolmogorov's complexity which connects them  -  to create an illusion of stream of consciousness.  Neurons are not needed at all.

One don't need to limit breeding ability to get genetic selection: just move those who you not interesting on into outside world. For example, i want to breed dogs who are good to live in mountains. I put a group of dogs on a mountain. As generations pass, those dogs which are good in living in the mountain will remain there and even move higher, and those who are not good in it, will move to live in plains. Those who live in plains may even have higher number of children.

Both answers are correct: manufacturing is slow and a lot of people are against vaccination. More about in this article in Russian. 

Population trust is low and many people deny vaccination. Only around 5 per cent of people in Moscow has been vaccinated, despite easy availability of vaccine for everybody in Moscow.  Also, there is a typical situation in Russia from Soviet times when Moscow is oversupplied and regions are undersupplied.  Ural region has run out of vaccine. 

In my circle, 80 per cent of people had covid, but only a few friends vaccinated (around 5-10 per cent based on the share of people who visited my last year wedding and later vaccinated). There are two explanation according to them: either they already had covid and has antibodies and don't see the reason to take risks of vaccination, or "they are too old" and afraid of side effects. Interestingly, Russian vaccine was initially approved only for people below 60, Also, unfortunately, Putin didn't take the shot and this didn't help the belief in vaccine.

Two more Russian vaccines are in the late stages of approval, and some people wait for them as they are based on more conventional technology: not viral vectors, but dead coronavirus.

Comment by avturchin on OpenAI: "Scaling Laws for Transfer", Hernandez et al. · 2021-02-05T09:43:20.258Z · LW · GW

gwern on reddit: 

"The most immediate implication of this would be that you now have a scaling law for transfer learning, and so you can predict how large a general-purpose model you need in order to obtain the necessary performance on a given low-n dataset. So if you have some economic use-cases in mind where you only have, say, _n_=1000 datapoints, you can use this to estimate what scale model is necessary to make that viable. My first impression is that this power law looks quite favorable*, and so this is a serious shot across the bow to any old-style AI startups or businesses which thought "our moat is our data, no one has the millions of datapoints necessary (because everyone knows DL is so sample-inefficient) to compete with us". The curves here indicate that just training a large as possible model on broad datasets is going to absolutely smash anyone trying to hand-curate finetuning datasets, especially for the small datasets people worry most about...

* eg the text->python example: the text is basically just random Internet text (same as GPT-3), Common Crawl etc, nothing special, not particularly programming-related, and the python is Github Python code; nevertheless, the transfer learning is very impressive: a 10x model size increase in the pretrained 'text' model is worth 100x more Github data!"

That is true for therapies which work on damage (SENS). But if we see aging as a process which creates the damages, than it is reasonable to stop it on early age. 

Also, I've seen a recent article "Longevity‐related molecular pathways are subject to midlife “switch” in humans" which implies that many interventions should happen early in life.

Thanks for great post!

It is safe enough to be sold OTC, and there are some research which connects with life extension effects. The real problem is that we don't have human tests of its effects on longevity, despite its widespread use. The first study like this will be TAME, which will explore life extension properties of metformin. There are several reasons why such studies are difficult to perform. Firstly, they are costly, but known safe things are non-patentable. Secondly, they need to be very long., and long human studies are especially costly.

Comment by avturchin on Anti-Aging: State of the Art · 2021-01-01T20:59:05.807Z · LW · GW

There is a problem with most anti-aging interventions: long expected duration of human trials, as results and lack of side effects will be obvious only decades after the start oа such trials. Without trials, FDA will never approve such therapies. 

However, there is a way to increase the speed of trials using biomarkers of aging - or testing of already known to be safe interventions, like vitamin D. But biomarkers need to be calibrated and safe interventions provide only small effects on aging. Thus, it looks like some way to accelerate trials is needed if we want radical solution to aging to 2030. What could it be?

Glitch in the Matrix: Urban Legend or Evidence of the Simulation? The article is here:
In the last decade, an urban legend about “glitches in the matrix” has become popular. As it is typical for urban legends, there is no evidence for most such stories, and the phenomenon could be explained as resulting from hoaxes, creepypasta, coincidence, and different forms of cognitive bias. In addition, the folk understanding of probability does not bear much resemblance to actual probability distributions, resulting in the illusion of improbable events, like the “birthday paradox”. Moreover, many such stories, even if they were true, could not be considered evidence of glitches in a linear-time computer simulation, as the reported “glitches” often assume non-linearity of time and space—like premonitions or changes to the past. Different types of simulations assume different types of glitches; for example, dreams are often very glitchy. Here, we explore the theoretical conditions necessary for such glitches to occur and then create a typology of so-called “GITM” reports. One interesting hypothetical subtype is “viruses in the matrix”, that is, self-replicating units which consume computational resources in a manner similar to transposons in the genome, biological and computer viruses, and memes.

Netherlands has a spike of infections from 5k to 14k during December. Thus even if this virus is not deadly per se, it will put more pressure on the medical system and will turn deadlier at the end.

If we run two non-communicating copies of the same AI, could it be helpful in detecting failures?

"Back to the Future: Curing Past Suffering and S-Risks via Indexical Uncertainty"

I uploaded the draft of my article about curing past sufferings.


The long unbearable sufferings in the past and agonies experienced in some future timelines in which a malevolent AI could torture people for some idiosyncratic reasons (s-risks) is a significant moral problem. Such events either already happened or will happen in causally disconnected regions of the multiverse and thus it seems unlikely that we can do anything about it. However, at least one pure theoretic way to cure past sufferings exists. If we assume that there is no stable substrate of personal identity and thus a copy equals original, then by creating many copies of the next observer-moment of a person in pain in which he stops suffer, we could create indexical uncertainty in her future location and thus effectively steal her consciousness from her initial location and immediately relieve her sufferings. However, to accomplish this for people who have already died, we need to perform this operation for all possible people thus requiring enormous amounts of computations. Such computation could be performed by the future benevolent AI of Galactic scale. Many such AIs could cooperate acausally by distributing parts of the work between them via quantum randomness. To ensure their success, they need to outnumber all possible evil AIs by orders of magnitude, and thus they need to convert most of the available matter into computronium in all universes where they exist and cooperate acausally across the whole multiverse. Another option for curing past suffering is the use of wormhole time-travel to send a nanobot in the past which will, after a period of secret replication, collect the data about people and secretly upload them when their suffering becomes unbearable.

Comment by avturchin on SIA fears (expected) infinity · 2020-12-02T14:32:12.189Z · LW · GW

It seems to me that is we have infinite population, which include all possible observers, then SIA merges with SSA. For example, in presumptuous philosopher, it would mean that there are two regions of the multiverse: one with trillion observers, and another with trillion of trillions, and it will be not surprising to be located in the larger one. 

SIA in PP becomes absurd only for a finite universe (and no other universes), where only one of two regions exists. But the absurdity is in the definition: it is absurd to think that the universe could be provably finite, as there should be some force above the universe which limits its size.
