Absurd Adventure And Amygdalectomy Advocacy
I am Daniel Böttger1. In 2023, my review of On The Marble Cliffs took second in the ACX book review contest, and Scott offered me the right to pitch him more essays. I have worked as a neuroscientist, so in 2024 I pitched a post with my theory of consciousness. Later that year, my connection to neuroscience took an unexpected turn, and I wrote about my experience getting diagnosed with brain ca
Nicholas Decker In Hell
I. Econblogger Nicholas Decker is not a fan of AI 2040: One of the centerpieces of AI 2040 is the proposal that we pause the development of AI at a high level, use the AI to research alignment, and only then proceed. I am skeptical of this, and not only because it seems impractical to get such cooperation. My first argument is that I do not believe a period of "researching alignment" is meaningf

Re: Re: Re: Pritchard On Liberal Happiness
In early July, Cassie Pritchard argued on Twitter that liberalism had failed; it bet the farm on economic progress making people happier, but although it delivered impressive economic progress, happiness had failed to follow. In late July, I countered that Pritchard had made a mistake by comparing happiness to income, when the literature instead supports a correlation of happiness with log(income

The Quest For Caffeine You Can Have At Night
Since the beginning of time, mankind has yearned to drink a cup of coffee at 5 PM and go to sleep at 10. But now there's an entire scientific subfield and several companies pandering to this absurd fantasy. Here's a simplified diagram of caffeine metabolism: Caffeine is converted to a different stimulating chemical called paraxanthine by a liver enzyme called CYP1A2, over a half-life of ~5 hours.
The Foothills Of Bay Area House Party
[previously in series: 1, 2, 3, 4, 5, 6, 7, 8, 9] Paul Graham once said that every city sends a message. New York says you should make more money. Berkeley says you should live better.

MacGregor The Bridge Builder
Old Scottish joke: A man at the bar is complaining: "You see that bridge there? I built it with my own hands! But do they call me 'MacGregor The Bridge-Builder'? No!

Open Questions On Open Weights
Last month, some of Silicon Valley's biggest companies signed an open letter supporting open-weights AI. Open weights AI is like open-source software, where the creator makes the raw code publicly available for free download. It's good insofar as it's the only way an AI can truly be the user's property, as opposed to something that companies like OpenAI or Anthropic temporarily let you use subjec
The Beauty Of Settled Science
Commenters convinced me I made a subtle mis-step in my framing of Psychology Research Is Mostly Fine. My framing emphasized that social priming studies had failed to replicate, but that many other subfields of psychology hadn't. This naturally led commenters to point to failed replications in other subfields. Although none of these were as bad as social priming, few or none were entirely problem-
Does Forecasting Have Room At The Top?
Superforecasting is the art/science/sport of predicting the future - for example, who will win elections, which countries will fight wars, when key technologies will be discovered. Over the past few years, it went from an obscure academic subfield to a multibillion dollar industry in the form of prediction markets. More recently, AI superforecasters have come close to the accuracy of top humans, a

Contra Pritchard On Liberal Happiness
Cassie Pritchard, on Twitter: I get why so many liberals are fundamentally disdainful of democracy these days—it's because liberalism is exhausted. It's out of answers.

"Stochastic terrorism" is the idea that if you spread fear and mistrust against a target, then eventually people will commit violence against that target, and it will be your fault, even if you never specifically said the words "you should commit violence".

AI Chip Regulation Is Not A Dystopian Surveillance State
This was one of the most common objections to Plan A. The plan proposes AI chip regulation to ensure that both China and America know where all the chips are, making their deal to regulate AI together "trustless" (ie neither side can defect even if they want to). Several people argued that this kind of regulation amounted to some kind of "Orwellian dystopia" or "global panopticon". I'm reminded of
Introducing Plan A
A Is For America It's increasingly clear that nobody has a plan for if this AI thing turns out to be real. Some people have suggestions, but they're all things like "regulate a little more" or "regulate a little less" or "react to things as they come up". This won't be enough. Not just because things may move too quickly - although they will - but because in order to regulate or react, you need to

The AI Superforecasters Are Here
The annual prediction market conference was earlier this month.

The Metaculus Threat To Democracy Index
In recent posts on Trump and dictatorship, people have asked me - how do you know you're not suffering from Trump Derangement Syndrome? I take this seriously; we've all lost loved ones to this condition. The best check on my reasoning would be an objective measure of the health of American democracy. There are several "democracy indices" that purport to do this, but they have a mixed reputation.
Should People Avoid Whole-Body Screening Info?
The most controversial part of last week's article on the Midjourney ultrasound scanner was medical experts' recommendation against whole-body screening (including existing whole-body screening technology using MRI). Isn't this crazy? Whole-body screening can save lives by detecting serious diseases like cancer. The experts counterargue that it finds so many false positives - minor zit-like imperf

Waiting For The Miracle
In 1917, three children in Fatima, Portugal claimed to have seen the Virgin Mary. They promised she would perform a miracle on a certain day in October. Nearly 100,000 pilgrims arrived, hoping to see whatever happened, and nearly all report that the sun turned pale, changed color, and spun around. Many other writers have investigated the children and their visions, but I was fixated on this sun mi

My AI Opinions

Timelines1 Define AGI as AI intelligent enough to do 90% of knowledge work jobs. I think there's a 25% chance of AGI by 20272, a 50% chance by 2034, and a 75% chance by 2045. Basic argument: In
Book Review: The Dialectical Imagination
The philosophers of the Frankfurt School practiced a technique called negative dialectics, where concepts are defined as much by what you can't say about them as what you can. Appropriately, the Frankfurt School has ended up defined by what you can't say about them. You can't say that they invented a new form of left-wing thought called Cultural Marxism. This would be (according to Wikipedia) the
Use AI This Election
I'm not saying AI is superintelligent or can decide better than you can. I'm saying that if you - like me - spend an hour or so doing research before voting on local seats, AI can aid that research very effectively. And if you don't do that research - because you weren't willing to waste an hour on it before - AI makes it so much faster that you might want to start. I gave Claude a prompt somethin
New Paradigms Won't Save You
One popular objection to AI concerns is to declare that LLMs can never be AGI. You need a "new paradigm". Therefore, AGI is so far in the future that it's not worth worrying about. A common counterargument is to claim that no, LLMs can become AGI. But even without that counterargument, I think the "therefore" fails on its own terms. The key question is: how much of a new paradigm do we need? The l

The Sigmoids Won't Save You
"All exponentials eventually become sigmoids" is an annoying AI talking point.

Nostalgebraist's Hydrogen Jukeboxes
In conclusion, the only good theory of taste is Nostalgebraist's. He wrote a post called Hydrogen Jukeboxes, analyzing the literary output of an AI called R1. This AI tried hard to write good fiction, which was part of the problem.

Last year I wrote a piece on artistic taste, which got many good responses from (eg) Ozy, Frank Lantz, and Sympathetic Opposition.

What Deontological Bars?
Constraint consequentialists believe that you should try to do good things that improve the world, unless those break hard-and-fast rules ("deontological bars"). For example, you shouldn't assassinate democratically-elected leaders, even very bad ones. Why not? Since bad leaders set bad policy, and bad policy can kill many thousands of people, wouldn't it be for the greater good? Because there's a
