LessWrong (Curated & Popular) ·

2026/04/21

Micheal Vassar's strategy for saving the world is horrifyingly counterproductive. Olivia's is worse. A note before we start: A lot of the sources cited are people who ended up looking kinda insane. This is not a coincidence, it's apparently an explicit strategy: Apply plausibly-deniable psychological pressure to anyone who might speak up until they crack and discredit themselves by sounding crazy or taking extreme and destructive actions. Here's Brent Dill explaining it: (later in t...

"10 non-boring ways I’ve used AI in the last month"...

LessWrong (Curated & Popular) ·

2026/04/21

I use AI assistance for basically all of my work, for many hours, every day. My colleagues do the same. Recent surveys suggest >50% of Americans have used AI to help with their work in the last week. My architect recently started sending me emails that were clearly ChatGPT generated.[1] Despite that, I know surprisingly little about how other people use AI assitance. Or at least how people who aren't weird AI-influencers sharing their marketing courses on Twitter or LinkedIn use AI. So ...

I have now had a few years of experience doing architectural and interior design for many spaces that people seem to really love (most widely known Lighthaven, but before that we also had the Lightcone Offices, though I've also played a hand in designing some of the most popular areas at Constellation a few years back). Most people (including me a few years back) have surprisingly bad introspective access into why a room makes them feel certain things. Most of the time, people's ability to...

Or, the end of the world is no excuse for sloppy work One morning when I was nine, my dad called me over to his computer. He wanted to show me this amazing Korean scientist who had managed to clone stem cells, and who was developing treatments to let people with spinal cord injuries – people like my dad – walk again on their own two legs. I don't remember exactly what he said next, or what I said back. I have a sense that I was excited too, and that I was upset when I learned the United ...

"Reevaluating AGI Ruin in 2026" by lc

LessWrong (Curated & Popular) ·

2026/04/20

It's been about four years since Eliezer Yudkowsky published AGI Ruin: A List of Lethalities, a 43-point list of reasons the default outcome from building AGI is everyone dying. A week later, Paul Christiano replied with Where I Agree and Disagree with Eliezer, signing on to about half the list and pushing back on most of the rest. For people who were young and not in the bay area, like me, these essays were probably more significant than old timers would expect. Before it became complete...

[Author's note: this post is the narrative version that explains my journey with OCD and how I treated it. The short version provides quick, actionable advice for treating OCD.] The following is the most painful experience I've ever had. Four years ago in the parking lot of my rock climbing gym… …my heart was pumping out of my chest, I was sweating profusely, and an overwhelming sense of panic and impending doom had a vice grip on my soul. A painful death was surely imminent. I felt li...

Epistemic status: Completely schizo galaxy-brained theory Lightcone[1] operates on a "generalist" philosophy. Most of our full-time staff have the title "generalist", and in any given year they work on a wide variety of tasks — from software development on the LessWrong codebase to fixing an overflowing toilet at Lighthaven, our 30,000 sq. ft. campus. One of our core rules is that you should not delegate a task you don't know how to perform yourself. This is a very intense rule and has l...

"Meaningful Questions Have Return Types" by Drake...

LessWrong (Curated & Popular) ·

2026/04/19

One way intellectual progress stalls is when you are asking the Wrong Questions. Your question is nonsensical, or cuts against the way reality works. Sometimes you can avoid this by learning more about how the world works, which implicitly answers some question you had, but if you want to make real progress you have to develop the skill of Righting a Wrong Question. This is a classic, old-school rationalist idea. The standard examples are asking about determinism, or free will, or consciousn...

"Carpathia Day" by Drake Morrison

LessWrong (Curated & Popular) ·

2026/04/18

(The better telling is here. Seriously you should go read it. I've heard this story told in rationalist circles, but there wasn't a post on LessWrong, so I made one) Today is April 15th, Carpathia Day. Take a moment to put forth an unreasonable effort to save a little piece of your world, when no one would fault you for doing less. In the early morning of April 15, the RMS Titanic began to sink with more than two thousand souls on board. Over 58 nautical miles away — too far to make ...

"Let goodness conquer all that it can defend" by habryka

LessWrong (Curated & Popular) ·

2026/04/18

Epistemic status: All of the western canon must eventually be re-invented in a LessWrong post, so today we are re-inventing modernism. In my post yesterday, I said: Maybe the most important way ambitious, smart, and wise people leave the world worse off than they found it is by seeing correctly how some part of the world is broken and unifying various powers under a banner to fix that problem — only for the thing they have built to slip from their grasp and, in its collapse, destroy muc...

"Do not conquer what you cannot defend" by habryka

LessWrong (Curated & Popular) ·

2026/04/16

Epistemic status: All of the western canon must eventually be re-invented in a LessWrong post. So today we are re-inventing federalism. Once upon a time there was a great king. He ruled his kingdom with wisdom and economically literate policies, and prosperity followed. Seeing this, the citizens of nearby kingdoms revolted against their leaders, and organized to join the kingdom of this great king. While the kingdom's ability to defend itself against external threats grew with each pers...

"Nectome: All That I Know" by Raelifin

LessWrong (Curated & Popular) ·

2026/04/16

TLDR: I flew to Oregon to investigate Nectome, a brain preservation startup, and talk to their entire team. They’re an ambitious company, looking to grow in a way that no cryonics organization has before. Their procedure is probably much better at saving people than other orgs, and is being offered for as little as $20k until the end of April — a (theoretical) 92% discount. (I bought two.) This early-bird pricing is low, in part, due to some severe uncertainties, in both the broader world an...

"Current AIs seem pretty misaligned to me" by...

LessWrong (Curated & Popular) ·

2026/04/15

Many people—especially AI company employees[1] —believe current AI systems are well-aligned in the sense of genuinely trying to do what they're supposed to do (e.g., following their spec or constitution, obeying a reasonable interpretation of instructions). [2] I disagree. Current AI systems seem pretty misaligned to me in a mundane behavioral sense: they oversell their work, downplay or fail to mention problems, stop working early and claim to have finished when they clearly haven't, a...

LessWrong (Curated & Popular) ·

2026/04/15

Here are two beliefs that are sort of haunting me right now: Folk who try to push people to uphold principles (whether established ones or novel ones), are kinda an important bedrock of civilization.Also, those people are really annoying and often, like, a little bit crazy And these both feel fairly important. I’ve learned a lot from people who have some kind of hobbyhorse about how society is treating something as okay/fine, when it's not okay/fine. When they first started complaining a...

"Morale" by J Bostock

LessWrong (Curated & Popular) ·

2026/04/14

One particularly pernicious condition is low morale. Morale is, roughly, "the belief that if you work hard, your conditions will improve." If your morale is low, you can't push through adversity. It's also very easy to accidentally drop your morale through standard rationalist life-optimization. It's easy to optimize for wellbeing and miss out on the factors which affect morale, especially if you're working on something important, like not having everyone die. One example is working at an ...

2026/04/14

It turns out that Anthropic accidentally trained against the chain of thought of Claude Mythos Preview in around 8% of training episodes. This is at least the second independent incident in which Anthropic accidentally exposed their model's CoT to the oversight signal. In more powerful systems, this kind of failure would jeopardize safely navigating the intelligence explosion. It's crucial to build good processes to ensure development is executed according to plan, especially as human ove...

"Only Law Can Prevent Extinction" by Eliezer Yudkowsky

LessWrong (Curated & Popular) ·

2026/04/14

There's a quote I read as a kid that stuck with me my whole life: "Remember that all tax revenue is the result of holding a gun to somebody's head. Not paying taxes is against the law. If you don’t pay taxes, you’ll be fined. If you don’t pay the fine, you’ll be jailed. If you try to escape from jail, you’ll be shot." -- P. J. O'Rourke. At first I took away the libertarian lesson: Government is violence. It may, in some cases, be rightful violence. But it all rests on violence; never f...

Epistemic status: I think this is true but don't think this post is a very strong argument for the case, or particularly interesting to read. But I had to get 500 words out! I think the 2013 conversation is interesting reading as a piece of history, separate from the top-level question, and recommend reading that. I think many people have a relationship with Anthropic that is premised on a false belief: that Dario Amodei believes in superintelligence. What do I mean by "believes" in supe...

"Daycare illnesses" by Nina Panickssery

LessWrong (Curated & Popular) ·

2026/04/13

Before I had a baby I was pretty agnostic about the idea of daycare. I could imagine various pros and cons but I didn’t have a strong overall opinion. Then I started mentioning the idea to various people. Every parent I spoke to brought up a consideration I hadn’t thought about before—the illnesses. A number of parents, including family members, told me they had sent their baby to daycare only for them to become constantly ill, sometimes severely, until they decided to take them out. This ...
