The social scene around AI and AI safety is more unpleasant than I realized. I'm sure there are other sides to it. But when you get a lot of men with too much money who think they're saving the world, surrounded by groupies, what do you expect? Read the long Bluesky thread about this, collected on one page: https://skywriter.blue/@segyges.bsky.social/3mvom4b4dn22q I can't confirm this stuff - I stay far away from this scene. And the sentence "AI Safety is Mostly a Sex Cult" is a massive exaggeration. But... (1/n) AI alignment Related

I was in the beta test for Jev—one fun way I've used it is as a kind of router that decides whether to process some chunk of text using deterministic rules, or to spend on a more expensive model. You can basically do cost discrimination instead of price discrimination! Quoting @CompleteSkeptic After co-inventing ChatGPT, I kept asking myself: why have superhuman chat models not led to AGI? I’ve spent the last 2 years in stealth building a new way to train models (RLCD), and a new type of frontier AI model that we are releasing today: Jev • 20-200x faster • 40-400x cheaper (w/ output toke… Related

The best thing you learn in consulting is how work gets done at every layer of an org, the different types of communication (and how to translate between them), and then how dramatically different industries work Quoting @VinIyengar A lot of VCs (myself included) used to shit on the ex-banker/consultant founder archetype. But I'm increasingly realizing I was wrong. In an age where building is easier and distribution/execution is still hard, these programs are the perfect training grounds. 2 years at McK/GS/etc. teaches you how… Related

What should be obvious is that inference, running a large language model, is the part that has to be cheap. Most of our hardware was not designed for that. LLM inference is limited by bandwidth. You do a great many matrix-vector multiplications against a huge weight matrix, and you barely reuse those weights. It is closer to streaming a video than to running a simulation or drawing a scene in a game. Graphics processors from Nvidia and others were built for something else. They pileed compute first, then bolted on high-bandwidth memory. It is expensive. An obvious answer is to invert the desi… LLMs Related

Author of The 4-Hour Workweek and Tools of Titans, and host of The Tim Ferriss Show podcast.
I definitely appreciate how many authors use their book primarily as a calling card to sell their speaking and consulting. I just don’t want to focus on those ancillary businesses, as I’m viewing my books mostly through the lens of a teacher who wants to affect change in the greatest number of people possible. I do worry about my ability to reach mass numbers of people with carefully crafted sequencing that actually changes beliefs and behavior. Related

So birds did not appear as a result of the dinosaurs going extinct. Birds lived alongside the dinosaurs for 100 million years. The birds were not new on the scene, and it's not like, "Oh, the dinosaurs died, and from the ashes rose the birds." No, they've been knocking around forever.

A lot more people have died of air pollution than nuclear reactors, for example. But most people worry more about living next to a nuclear reactor than a coal plant. But something about the way we’re wired is that although there’s many different kinds of risks we have to confront, the ones that make a good climax scene of a movie carry much more weight with us than the ones that are very bad over a long period of time but on a slow burn.

Steinbeck deploys a standard third person omniscient narrative style that avoids all the flash of the modernists, and then postmodernists, that soon after took over the literary scene. But in his hands, it's enough. I still think about the ending.

What is a korrent?
A korrent is a belief a person has stated in their own words: one
sentence stating the claim, backed by a quote and a source, kept at
korrents.com .
Under a name here, the quoted block is what they actually said.
The korrent beneath it is the claim those words support, in
korrents' wording — tap it to see the record, its source, and who
else holds it.
Nobody here wrote their own korrents. They are compiled from public
statements, and a person can change their mind, which is recorded too.

About the English under a post
Some people here publish in a language other than English. Where they
do, this site shows a machine translation beneath the post, in
this typeface — the site's own, not theirs.
The post itself is never changed, moved or hidden: what is set in the
serif above is exactly what the person published, and it is what to
quote them on. A translation can be wrong in ways that matter,
especially about tone.
Only the post's own words are translated. A quoted post, a linked
article and a belief on korrents.com
are left in their original language.
