"Over the past few years, some people have updated toward pretty short AGI timelines. If your timelines are really short, then maybe you shouldn't sign up for cryonics, because the singularity – good or bad – is overwhelmingly likely to happen before you biologically die"  

But such a scenario means there is less value in saving for retirement and this should make it financially easier for you to sign up for cryonics.  Also, the sooner we get friendly AGI, the sooner people in cryonics will be revived meaning there is a lower risk that your cryonics provider will fail before you can be revived.

I did a series of podcasts on COVID with Greg Cochran and Greg was right early on.  Greg has said from the beginning that the risk of a harmful mutation is reasonably high because the virus is new meaning there are likely lots of potential beneficial mutations (from the virus's viewpoint) that have not yet been found.

Yes for high concentration of observers, and if high tech civilizations have strong incentives to grab galactic resources as quickly as they can  thus preventing the emergence of other high tech civilizations, most civilizations such as ours will exist in universes that have some kind of late great filter to knock down civilizations before they can become spacefaring.

Thanks, that's a very clear explanation. 

Comment by James_Miller on Snyder-Beattie, Sandberg, Drexler & Bonsall (2020): The Timing of Evolutionary Transitions Suggests Intelligent Life Is Rare · 2020-11-24T12:51:14.401Z · LW · GW

At the end of Section 5.3 the authors write "So far, we have assumed that we can derive no information on the probability of intelligent life from our own existence, since any intelligent observer will inevitably find themself in a location where intelligent life successfully emerged regardless of the probability. Another line of reasoning, known as the “Self-Indication Assumption” (SIA), suggests that if there are different possible worlds with differing numbers of observers, we should weigh those possibilities in proportion to the number of observers (Bostrom, 2013). For example, if we posit only two possible universes, one with 10 human-like civilizations and one with 10 billion, SIA implies that all else being equal we should be 1 billion times more likely to live in the universe with 10 billion civilizations. If SIA is correct, this could greatly undermine the premises argued here, and under our simple model it would produce high probability of fast rates that reliably lead to intelligent life (Fig. 4, bottom)...Adopting SIA thus will undermine our results, but also undermine any other scientific result that would suggest a lower number of observers in the Universe. The plausibility and implications of SIA remain poorly understood and outside the scope of our present work."  

I'm confused, probably because anthropic effects confuse me and not because the authors made a mistake.  But don't the observer selection effects the paper uses derive information from our own existence, and if we make use of these effects shouldn't we also accept the implications of SIA?  Should rejecting SIA because it results in some bizarre theories cause us to also have less trust in observer selection effects?

Comment by James_Miller on What is the current bottleneck on genetic engineering of human embryos for improved IQ · 2020-10-24T16:42:15.836Z · LW · GW

Think of mutational load as errors.  Reducing errors in the immune system's genetic code should decrease the risk of pandemics.  Reducing errors in people's brains should greatly increase the quality of intellectual output.  Hitting everyone in the head with a hammer a few times could, I suppose, through an extraordinarily lucky hit cause someone to produce something good that they otherwise wouldn't but most likely the hammer blows (analogous to mutational load) just gives us bad stuff.

Comment by James_Miller on What is the current bottleneck on genetic engineering of human embryos for improved IQ · 2020-10-23T13:41:55.008Z · LW · GW

The best way to radically increase the intelligence of humans would be to use Greg Cochran's idea of replacing rare genetic variations with common ones thereby greatly reducing mutational load.  Because of copying errors, new mutations keep getting introduced into populations, but evolutionary selection keeps working to reduce the spread of harmful mutations.  Consequently, if an embryo has a mutation that few other people have it is far more likely that this mutation is harmful than beneficial.  Replacing all rare genetic variations in an embryo with common variations would likely result in the eventual creation of a person much smarter and healthier than has ever existed.  The primary advantage of Cochran's genetic engineering approach is that we can implement it before we learn the genetic basis of human intelligence.  The main technical problem, from what I understand, from implementing this approach is the inability to edit genes with sufficient accuracy, at sufficiently low cost, and with sufficiently low side effects.

Much of the harm of aging is the increased likelihood of getting many diseases such as cancer, heart disease, alzheimer's, and strokes as you age.  From my limited understanding, Metformin reduces the age-adjusted chance of getting many of these diseases and thus it's reasonable, I believe, to say that Metformin has anti-aging effects.

Metformin as a rationalist win.  For several years I have been taking 2 grams of Metformin a day for anti-aging reasons.  There is a vast literature on Metformin and as a mere economist I'm unqualified to summarize it.  But my (skin-in-the-game) guess is that all adults over 40 (and perhaps simply all adults) should be taking Metformin and I would love if someone with a bio-background wrote up a Metformin literature review understandable to those of us who understand statistics but not much about medicine.  The reason why Metformin might be universally beneficial and yet not generally taken is because no one holds a patent on Metformin (it's cheap), in the US you need a prescription to get it, and the medical system doesn't consider aging to be a disease.

Our estimate of which of the four possibilities is correct is conditional on us living in a universe where we observe that the predictor always guesses correctly.  If we put aside cheating (which should almost always be our guess if we observe something happening that seems to defy our understanding of how the universe operates) we should have massive uncertainty concerning how randomness and/or causation operates and thus not assign too low a probability to either (2) or (3).

To destroy an aircraft carrier you must first find it and in a war the US would prioritize taking out the enemy's ability to locate our aircraft carriers. Since the carriers move, knowing were one was an hour ago might not be enough information to destroy the carrier. In the next future aircraft carriers might be protected by laser anti-missile systems that could handle having only two seconds to destroy multiple incoming missiles.

Comment by James_Miller on Why COVID-19 prevention at the margin might be bad for most LWers · 2020-05-10T00:48:23.866Z · LW · GW

We are quickly learning how to treat the virus. Your grandparents chances of survival if they get COVID-19 are likely significantly higher if they get it in three months than today. As the virus is new to humans there are likely a lot of "low-hanging fruit" mutations for evolution to find, and the more people the virus is in the more chance it will stumble upon a mutation that makes it better at invading the cells of young people. We don't have a good estimate of how much long-term harm it does to people it doesn't kill. While if you get the virus this year, you will probably be safe from it next year, we don't know this for sure. We don't yet know if viral loads matter and it could be that the rapid initial exponential growth of the virus once it is in you means it really isn't important what your initial exposure is.

Comment by James_Miller on How likely is the COVID-19 apocalyptic scenario? · 2020-04-22T12:45:12.275Z · LW · GW

The probability of this happening is very low. We have effective coronavirus vaccines for pigs (although not for COVID-19). For most viruses people recover from, they keep immunity and we don't have good evidence that COVID-19 is different. While COVID-19 might do some harm to most people that recover, if the harm was on average significant we should have a lot more evidence of this. Also, the space of possible effective treatments is huge and it seems likely that within 2 years (perhaps even two months) we will be able to greatly improve outcomes for the infected. Finally, keep in mind that we have just started to fight COVID-19, and so we have not already tried and failed with all the obvious approaches and this should make us relatively optimistic about coming up with effective treatments or vaccines.
