LessWrong (Curated & Popular)

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 completely consumed with AI discussions, LessWrong was a forum about the art of human rationality, and most internet rationalists I knew thought of it as a mix between that and a place to write for people who liked the sequences. It wasn't until 2022 that we were exposed to all of the doom arguments in one place, and it was the first time in many years that Eliezer had publicly announced how much more dire his assessment was since the Sequences. As far as I can tell AGI Ruin still remains his most authoritative explanation of his views.

It's not often that public intellectuals will literally hand you a document explaining why [...]

[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 like I was defusing a bomb that was on the verge of exploding.

In reality, I was standing outside of my car after locking it with only one *beep* of my key fob, instead of my normal 5-6 *beeps* I usually do.




The reason I undertook this (basically suicidal) task was because it was getting annoying how many more *beeps* it was taking for my car to feel locked. It used to be only 2-3 *beeps* a few years ago. Now it was 5-6. In a few more years, it might take as many as 10-20 *beeps*.

One time on a hike with friends, a sense of panic overcame me. [...]

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 lots of implications about how we operate, so I've spent a lot of time watching people learn things they didn't previously know how to do.

My overall observation (and why we have the rule) is that smart people can learn almost anything. Across a wide range of tasks, most of the variance in performance is explained by general intelligence (foremost) and conscientiousness (secondmost), not expertise. Of course, if you compare yourself to someone who's done a task thousands of times you'll lag behind for a while — but people plateau surprisingly quickly. Having worked with experts across many industries, and having dabbled in the literature around skill transfer and training, there seems to be little difference [...]

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 consciousness. The standard fix is to go meta. Ask yourself, "Why do I feel like I have free will" or "Why do I think I have consciousness" which is by itself an answerable question. There is some causal path through your cognition that generates that question, and can be investigated. This works great for some ideas, and can help people untangle some self-referential knots they get themselves into, but I find it unsatisfying. Sometimes I want to know the answer to the real question I had, and going meta avoids it, or asks a meaningfully different question instead of answering it. Over time, I've stumbled across another way to right wrong questions that I find myself using more [...]

(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 it in time — sailed the RMS Carpathia, a small, slow, passenger steamer. The wireless operator, Harold Cottam, was listening to the transmitter late at night before he went to bed when he got a message from Cape Cod intended for the Titanic. When he contacted the Titanic to relay the messages, he got back a distress signal saying they hit an iceberg and were in need of immediate assistance. Cottam ran the message straight to the captain's cabin, waking him.

Captain Arthur Rostron's first reaction upon being awoken was anger, but that anger dissolved as he came to understand the situation. Before he'd [...]
