.Jacob Kimmel thinks that the functionality to reverse aging already exists in our epigenome. But then why didn't evolution already optimize for longevity? Jacob explains that if you consider evolution as an optimizer, the gradients flow in a really surprising way. Naively, it seems like evolution should want you...

.Naval: You have a beautiful definition of knowledge, which most people don’t even try to tackle, about how knowledge perpetuates itself in the environment. You gave some really good examples. One was around genes. Successful, highly adapted genes contain a lot of knowledge and can cause themselves to be replicated because they’re survivors. In the same way, knowledge itself is a survivor, in that if you transmit to me the knowledge of how to build a computer, it’s an incredibly useful thing. I’m going to build more and more computers and that knowledge will be passed on. Your underlying point that you repeated here was if you want to understand the physical universe you have to understand knowledge, because it is the thing that over time takes over and changes more and more the universe—more than almost anything else. You have to understand all the explanations behind it. You can’t just say “particle collisions” because that explains everything, so it explains nothing. It’s not a useful level to operate at. Therefore, the things that create knowledge are uniquely influential in the universe. And as far as we know, there are only two systems that create knowledge. There’s evolution and there are humans. But is there a difference even between these two forms of knowledge creation, between evolution and between humans? David Deutsch: Yes. I have argued that the human way of creating knowledge is the ultimate one, that there aren’t any more powerful ones than that. This is the argument against the supernatural. Assuming that there is a form of knowledge creation that’s more powerful than ours is equivalent to invoking the supernatural, which is therefore a bad explanation—as invoking the supernatural always is. The difference between biological evolution and human creative thought is that biological evolution is inherently limited in its range. That’s because biological evolution has no foresight. It can’t see a problem and conjecture a solution. Whenever biological evolution produces a solution to something, it’s always before natural selection has even begun. This is Charles Darwin’s insight. This is the difference between Charles Darwin’s theory of evolution and the other theories of evolution that had been around for a century or more before that, including Charles Darwin’s grandfather and Lamarck. The thing they didn’t get is that the creation of knowledge in evolution begins before. That means that biological evolution can’t reach places that are not reachable by successive improvements, each of which allows a viable organism to exist. Creationists say that biological evolution has, in fact, reached things that are not reachable by incremental steps, each of which is a viable organism. They’re factually mistaken. The thing which they have in mind is the idea of a creator who can imagine things that don’t exist and who can create an idea that is not the culmination of a whole load of viable things. A thinking being can create something that’s a culmination of a whole load of non-viable things. Explanatory creativity makes humans unique Out of all the billions and billions of species that have ever existed, none of them has ever made a campfire, even though many of them would’ve been helped by having the genetic capacity to make campfires. The reason it didn’t happen in the biosphere is that there is no such thing as making a partially functional campfire; whereas there is, for example, with making hot water. The bombardier beetles squirt boiling water at their enemies. You can easily see that just squirting cold water at your enemies is not totally unhelpful. Then making it a bit hotter and a bit hotter. Squirting boiling water no doubt required many adaptations to make sure the beetle didn’t boil itself while it was making this boiling water. That happened because there was a sequence of steps in between, all of which were useful. But with campfires, it’s very hard to see how that could happen. Humans have explanatory creativity. Once you have that, you can get to the moon. You can cause asteroids which are heading towards the earth to turn around and go away. Perhaps no other planet in the universe has that power, and it has it only because of the presence of explanatory creativity on it.

Levin's new episode "Stewarding the Flame" is out just now :) The focus: At the dawn of AGI, how can we make sure that the intelligences we're conjuring will add to a FLOURISHING of the process-of-life, rather than a brute optimizer that squashes life? As we get closer to superintelligence few topics are more pressing, and few people are thinking as deeply about the nature of life and intelligence as Levin. Big takeaways: -- Humans and non-human life will have to change if it wants to persist, this happens at every scale of the living process -- There is a much wider state-space of minds that we don't understand, but we should have a better grip on how intelligence works / comes into being before we build an AGI we don't control (because it might not carry the self-creating flame of life, it might be a brute optimizer) -- Levin is overall optimistic that the process of evolution and expanding life (even in forms that we don't understand today as "life" in a bio sense) will most likely continue to bubble up and continue to flourish in forms beyond us (i.e. the process is robust, and we'd REALLY have to mess something up to knock that trajectory off course) Some of the most important parts of this episode: 00:13:17 - Why MUST you transform if you wish to persist? 00:18:50 - Where does the self-preserving, self-expanding impulse "come from" in life? 00:33:30 - What do we need to understand better in order to make AGI "go well" (not just for how it treats humans, but for its ability to expand flourishing intelligence into the future)? 00:48:33 - [A deep-dive into the Flame paradigm (the process-of-life), and the Torch paradigm (pretending homo sapiens sapiens can/should rule all possible futures in a static hominid form).] There's a TON more in here, but this is a start. I sincerely hope you enjoy this episode with Mike!

I asked Nick if an analogy to Github repos would help illustrate the advantages of sexual recombination over asexual cloning or lateral gene transfer. Recombination is like a normal pull request - you have an organized diff at the same site as the previous functionality, and then you merge back if maintainer evaluates the new code to be better (analogy is imperfect, but this is like evolution driving that allele into fixation if it confers advantage). Asexual reproduction is if you just forked the repo millions of times, making random char changes. And even if a couple of these forks end up accidentally producing an improvement, there’s no way for them to merge back into "master". Without recombination, you don't have systematic pooling of the genes. So you can either be on the lineage with beneficial mutation A or beneficial mutation B, not both. This is known as clonal interference. I thought the problem with horizontal gene transfer in bacteria is that it's not like an organized diff. It's like if you just took a random 500 line snippet and shoved it in some totally different repo in totally random place. But actually Nick corrected me on this point of the analogy. The problem with lateral gene transfer is not that you don't have an organized diff - the problem is LGT is that its not scalable to eukaryotes' large genomes (1000x larger than bacteria). You can't systematically exchange tens of thousands of genes (in order to drive up the variance evolution relies upon) through LGT, but you can through recombination. This kind of systematic parallel search across the genome became necessary once the genome size exploded after the endosymbiosis of the ancestral mitochondria (which kept shoving a bunch of its genes into the host cell’s DNA).

The reason you age has nothing to do with bad genetics. Evolution literally never NEEDED you to live past 40. And now one lab is overriding millions of years of biological programming. David Sinclair explained the logic: in prehistoric times, most humans died from famine, disease, or war by age 30 to 40. If you were born with a mutation that let you live to 90, it was useless. You'd be killed by a predator or a neighboring tribe long before it mattered. So evolution optimized for one thing: breed fast, die young. But here's the proof this can change: Species with no predators evolved dramatically longer lifespans. Bowhead whales live for hundreds of years. Bristlecone pine trees have been alive since the pyramids were built. The reason? Nothing eats them. So evolution gave them stable epigenetic systems. Their cells don't lose identity. They barely get cancer. Humans never got that biological upgrade because we never survived long enough for evolution to select for it. Sinclair's lab proved this by engineering mice with accelerated DNA breaks. No cancer. No mutations. Just broken chromosomes that got repaired imperfectly. Within 10 months, those mice aged 50% faster than their identical twins. Gray hair. Frailty. Every disease of aging. All triggered by the same mechanism his theory predicted. Then they reversed it. Evolution built us to reproduce and die. Science is rewriting that code in real time. — David Sinclair

The subject of 'owning a slave' is dense. It is something we hear a lot when we are in the FemDom Realm. Is it just fantasy? Can it actually be a lifestyle? How do we navigate this type of dynamic? How do we even get to that level of D/s? In this short clip [Exerpt from SLAVE TRAINING Part 2] I want to already bring to your attention one thing that will define if your desire for a slave (or desire as a slave) is touching more on a fantasy or... how can you actually navigate this in a realistic way. No one person 'can do it all' or should be expected to. If you want your slave to be 'the best' , assign them a specific role in which they can excel... and then build upon that. Once they 'master' your housekeeping (which takes quite a bit of real training), they can move to other levels. And an important note I want to leave here... make them EARN access to certain things in your life that sometimes you just want to delegate because you don't want to manage or don't know how to manage. Entrusting them with serious tasks that can affect your life, your business, your reputation, are on top of the ladder. Are they even qualified for the thing you want them to take off your shoulders? Start small and allow them to grow in their submission, to develop their skills and to learn how to best satisfy you without setting them up for failure by expecting too much, too quick. In the end, if you want this to truly work, you have to approach it from a place that transcends the roles. As this is consensual power exchange. And you both want to be fulfilled in that relationship.
