2024/07/19

Eliezer Yudkowsky periodically complains about people coming up with questionable plans with questionable assumptions to deal with AI, and then either: Saying "well, if this assumption doesn't hold, we're doomed, so we might as well assume it's true."Worse: coming up with cope-y reasons to assume that the assumption isn't even questionable at all. It's just a pretty reasonable worldview.Sometimes the questionable plan is "an alignment scheme, which Eliezer thinks avoids the hard part of the p...

This post was inspired by some talks at the recent LessOnline conference including one by LessWrong user “Gene Smith”.Let's say you want to have a “designer baby”. Genetically extraordinary in some way — super athletic, super beautiful, whatever.6’5”, blue eyes, with a trust fund.Ethics aside[1], what would be necessary to actually do this?Fundamentally, any kind of “superbaby” or “designer baby” project depends on two steps:1.) figure out what genes you ideally want;2.) create an embryo with...

This is a link post.Editor's note: Somewhat after I posted this on my own blog, Max Chiswick cornered me at LessOnline / Manifest and gave me a whole new perspective on this topic. I now believe that there is a way to use poker to sharpen epistemics that works dramatically better than anything I had been considering. I hope to write it up—together with Max—when I have time. Anyway, I'm still happy to keep this post around as a record of my first thoughts on the matter, and because it's better...

This is a linkpost for https://www.tracingwoodgrains.com/p/reliable-sources-how-wikipedia-admin, posted in full here given its relevance to this community. Gerard has been one of the longest-standing malicious critics of the rationalist and EA communities and has done remarkable amounts of work to shape their public images behind the scenes.Note: I am closer to this story than to many of my others. As always, I write aiming to provide a thorough and honest picture, but this should be read as ...

LessWrong (Curated & Popular) ·

2024/07/04

I haven't shared this post with other relevant parties – my experience has been that private discussion of this sort of thing is more paralyzing than helpful. I might change my mind in the resulting discussion, but, I prefer that discussion to be public. I think 80,000 hours should remove OpenAI from its job board, and similar EA job placement services should do the same. (I personally believe 80k shouldn't advertise Anthropic jobs either, but I think the case for that is somewhat less cle...

This is a linkpost for https://www.bhauth.com/blog/biology/cancer%20vaccines.html cancer neoantigensFor cells to become cancerous, they must have mutations that cause uncontrolled replication and mutations that prevent that uncontrolled replication from causing apoptosis. Because cancer requires several mutations, it often begins with damage to mutation-preventing mechanisms. As such, cancers often have many mutations not required for their growth, which often cause changes to structure of so...

Let's name this hypothetical movement the Effective Samaritans.Like the EA movement of today, they believe in doing as much good as possible, whatever this means. They began by evaluating existing charities, reading every RCT to find the very best ways of helping.But many effective samaritans ...

About a year ago I decided to try using one of those apps where you tie your goals to some kind of financial penalty. The specific one I tried is Forfeit, which I liked the look of because it's relatively simple, you set single tasks which you have to verify you have completed with a photo.I’m generally pretty sceptical of productivity systems, tools for thought, mindset shifts, life hacks and so on. But this one I have found to be really shockingly effective, it has been about the biggest po...

ARC's current research focus can be thought of as trying to combine mechanistic interpretability and formal verification. If we had a deep understanding of what was going on inside a neural network, we would hope to be able to use that understanding to verify that the network was not going to behave dangerously in unforeseen situations. ARC is attempting to perform this kind of verification, but using a mathematical kind of "explanation" instead of one written in natural language.To help eluc...

LessWrong (Curated & Popular) ·

2024/06/25

Summary: Superposition-based interpretations of neural network activation spaces are incomplete. The specific locations of feature vectors contain crucial structural information beyond superposition, as seen in circular arrangements of day-of-the-week features and in the rich structures. We don’t currently have good concepts for talking about this structure in feature geometry, but it is likely very important for model computation. An eventual understanding of feature geometry might look like...

Crossposted from the AI Alignment Forum. May contain more technical jargon than usual.This is a link post.TL;DR: We published a new paper on out-of-context reasoning in LLMs. We show that LLMs can infer latent information from training data and use this information for downstream tasks, without any in-context learning or CoT. For instance, we finetune GPT-3.5 on pairs (x,f(x)) for some unknown function f. We find that the LLM can (a) define f in Python, (b) invert f, (c) compose f with other ...

“I would have shit in that alley, too” by Declan Molony

After living in a suburb for most of my life, when I moved to a major U.S. city the first thing I noticed was the feces. At first I assumed it was dog poop, but my naivety didn’t last long.One day I saw a homeless man waddling towards me at a fast speed while holding his ass cheeks. He turned into an alley and took a shit. As I passed him, there was a moment where our eyes met. He sheepishly averted his gaze.The next day I walked to the same place. There are a number of businesses on both sid...
