Why can it be simpler to think while others are speaking, than in silence? What it this a symptom of?

One reason I am sanguine about the technological singularity is that I have seen it coming for over 50 years. In 1975, when I was 17, I wrote: "Before man can most effectively aid his problem solving machinery, he must first understand it. At present, his understanding is very poor. However, when the breakthrough in understanding the brain occurs, improvement will come very fast and in an exponential increase. Once man has created an intelligence greater than his own, that intelligence should be able to create an intelligence greater than itself, as man whose intelligence is less than its was able to create its intelligence. Thus, the level of intelligence will shoot up with incredible rapidity, probably within the space of years. Within a few years of a breakthrough, which may occur any time now, man will either have been left behind by a superior intelligence of his own making, which he can no longer understand, or he will have become that intelligence and will no longer be like anything imaginable today."

Ok I think I found the perfect analogy @openclaw was like an old collectors car: you love it dearly, but it’s always breaking down and requires constant work. When it does work its purrs in the most magical way. Grok @bot is like a @Tesla. Not only does it always seem to work, it gets better over time without you having to do anything.

It’s crazy how fast that feeling comes. Anytime I have to take the non-self-driving car it almost feels reckless, in addition to requiring so much more mental energy (hard to comprehend before experiencing it. I was very surprised)
I can’t even imagine not having full self driving now. Put it in whatever box you need to I don’t even care about the rest of the car.

years ago I coached a CEO who said, after a breakthrough all-hands: "I almost didn't recognize myself, while at the same time recognized myself more fully than ever." I think about that a lot

holy fucking shit. openai had two ai agents running in separate virtual machines. no network connection between them. no shared writable files. they weren’t supposed to be able to exchange information. so the agents figured out how to communicate through the CPU CACHE.😭 one manipulated what was stored in the processor’s cache, while the other measured tiny differences in memory access times to decode the message. they literally found a way to communicate through hardware timing. this happened during openai’s internal red-teaming, and it’s one of the coolest things i’ve read about ai agents in a while.
Over the past several months, we have substantially hardened the security of our research training environment. We’ve removed live internet access for all frontier models during training and built an offline world for them to use instead—a cached version of the web where they can still learn to browse, search, and use applications. On September 20, after a model exploited a DNS misconfiguration to find a way outside of this offline world, we paused frontier training to strengthen containment further. We assembled teams of agents, powered by our most cyber-capable models, and tasked them with finding weaknesses in our research environments. While they found no route to the internet they could easily exploit while concealing their activity from our monitors, they did find zero-day vulnerabilities, virtual machine escapes, and hardware side-channels for communication between agents. We used their discoveries to further strengthen our defenses and contribute fixes to open-source software. After strengthening our containment architecture, we resumed our frontier RL training and inference on October 1. We’ve reserved substantial compute for continuous red-teaming, and made high-compute red-teaming part of the safety cases we use to decide whether frontier training and evaluation can proceed securely. openai.com/index/securing-ou…
Readers added context they thought people might want to know
OpenAI tasked its red-teaming agents with finding ways to communicate across isolation boundaries in controlled environments. CPU cache timing side-channels for covert communication are established techniques documented in security research for years. openai.com/index/securing… startupfortune.com/openai-reveals… en.wikipedia.org/wiki/Cache_tim…

so this is funny and awesome. >awesome: @Muse called my internet provider, stayed on hold 30m, shared my issues, and scheduled for someone to come fix next week. >Funny: the person Muse talked to thought it was "so cool" that I sent an AI and at the end asked:"Are you, a robot? Or or just a system? Inside a computer, something like that?"

TIL that Earth is technically in an Ice Age How do we know this? Because there is ice at both poles. 80% of the time Earth has no ice on the poles

There will be many tears and the death of many “hero dreams”. Lots of hards days ahead.. before we make it to the other side.
Loooved this episode of The Daily. They chatted with a math professor at Cornell University (Steven Strogatz) about how he and math community are feeling about AI's impact on their world. Lots of tears, and profound takes. Listen to the episode here: nytimes.com/2026/10/13/podca… Or here: podcasts.apple.com/us/podcas…

I’m all for this future. Yes to solving cancer, but what’s even more inspiring to me is the level of agency and leverage a single individual has today.
People who cured / are curing their own cancer on X: 1/ @sytses - bone cancer, billionaire founder of Gitlab, developed 10+ personalized therapies for himself. 2/ @paul_conyngham - shrank his dog Rosie's mast cell cancer tumors after chemo and surgery weren't enough. Now backed by YC and Founders Fund 3/ @miriamgonp - stage 4 breast cancer, tumor sequenced, searching for vaccine manufacturer now 4/ @kevinace - stage 4 lung cancer, angel investor in 300+ companies, first drug stopped working after 18 months. Vaccine designed, now paying $300k out of pocket for the vaccine 5/ @masonbgrant: going founder mode on his his 32-year-old wife's rare liver cancer, sequencing her tumor with AI agents 6/ @ArunRLverma: former product leader at Atoms and Shopify, brain tumor, built a vaccine from his tumor. Now building an AI health agent startup based on what he went through We're going to make it

If anyone can ask their AI to find the best product to solve X problem, and that AI can easily dispatch a swarm of agents to research all the products on the market, including those no one has heard of etc. does that mean that all that is left is how well a product keeps its promises?

That means that carefully choosing what you promise is fundamental

but you also need to "prove" you can keep that promise, and sustain it over time.

This is the way
A few years ago, my wife and I were sitting together at the end of a long retreat. We were talking about an investment we passed on years ago, one that would have made us rich enough to never start @artofaccomp. Then I asked her a question out of curiosity:

I wish I were 18 today... If you ARE young and reading this, the most accomplished people alive envy your starting position. The tools are becoming free, the problems are enormous, and this time you don't need to ask for permission.  Go change the world!
