AI Analysis

Karpathy shares detailed summary of his Sequoia Ascent 2026 fireside chat covering three themes: 1) LLMs enabling entirely new paradigms beyond speeding things up (menugen, install.md, LLM knowledge bases), 2) explaining 'jaggedness' of LLMs via verifiability and economics/TAM, 3) the agent-native economy with decomposition into sensors/actuators/logic across computing paradigms

Fireside chat at Sequoia Ascent 2026 from a ~week ago. Some highlights: The first theme I tried to push on is that LLMs are about a lot more than just speeding up what existed before (e.g. coding). Three examples of new horizons: 1. menugen: an app that can be fully engulfed by LLMs, with no classical code needed: input an image, output an image and an LLM can natively do the thing. 2. install .md skills instead of install .sh scripts. Why create a complex Software 1.0 bash script for e.g. ins

Sam Altman announces rollout of GPT-5.5-Cyber, a frontier cybersecurity model, to critical cyber defenders in coming days, with plans to work with government on trusted access

we're starting rollout of GPT-5.5-Cyber, a frontier cybersecurity model, to critical cyber defenders in the next few days. we will work with the entire ecosystem and the government to figure out trusted access for cyber; we want to rapidly help secure companies/infrastructure.

AI Analysis

François Chollet argues AI automates tasks not jobs; when tasks get cheaper, demand for the job grows. Claims AI lacks autonomy and cannot operate without supervision, noting zero jobs from 2022 can be performed end-to-end by AI

AI automates tasks, not jobs, and when a task gets cheaper, demand for the job grows. AI cannot automate jobs end-to-end because it lacks autonomy and cannot operate without supervision. There is still zero job from 2022 that can be performed end-to-end by AI, not even translator or customer support associate.

AI Analysis

Following yesterday's Research on AI risk reporting, Emollick provides detailed analysis of Anthropic's Mythos model and cybersecurity implications - noting it's a general model restricted due to cyber capabilities, and questioning whether OpenAI/Google will face similar restrictions for equivalent models since risk is self-reported

Mythos seems to be a very capable model based on available information, but it is not a cybersecurity model - it is an advanced general purpose model that happens to be good at cyber because it is good at a bunch of things. Anthropic stated that they were worried about cybersecurity risk, and their efforts mean it is a restricted model with lots of government attention. OpenAI and Google will pass the same threshold soon (and may already have with unreleased models). and the question is whether

jerryjliu0 (LlamaIndex founder) argues filesystems are the new default abstraction for agents (the 'new RAG stack in 2026'), praises a tool combining filesystem semantics with git versioning

This is really well thought out. Filesystems are the new default abstraction for agents to interact with documents (the new RAG stack in 2026). The issue is actually figuring out how to productize this; you can't "productize" Claude Code over a local file system. Seems like this tool has all the semantics of filesystems with the versioning of git

Gary Marcus highlights a Verge article arguing Oracle is dangerously overextended, with $300B+ of its $553B in remaining performance obligations tied to OpenAI. Questions what happens if OpenAI fails and whether government bailout might follow

“If you want to know whether the AI bubble is bursting, there’s only one publicly traded company that will tell you: Oracle…” “Oracle has the lowest credit rating. It also has the greatest debt load, even before the infrastructure buildout came into play…” “OpenAI… is by far the biggest customer represented in Oracle’s remaining performance obligations (RPOs), which represent how much money Oracle is slated to earn from its existing contracts. Of the $553 billion in RPOs that Oracle reported

AI Analysis

natolambert expresses deep concern about companies/governments controlling access to powerful AI, advocates for open models as counterbalance to power concentration

I worry deeply already about companies controlling access to very powerful AI, which will come in a soft form with very expensive subscriptions. This is a step further, with the government confusingly exerting control without clear explanation. This control of AI can create massive dystopian societies. It’ll rapidly lead to concentration of power. Having open models follow closely in capabilities is a great way to minimize political and power games here.

Gary Marcus shares concerns about 'cognitive surrender' from GenAI - recent graduates producing polished AI-generated work but unable to explain their reasoning or demonstrate real thinking when questioned

Warning: GenAI-induced cognitive surrender may kill innovation. Consider the following, from CEO @wadhwa’s newsletter: “I have been speaking with recent graduates in India, many of them highly recommended, and on paper they look exceptional. The emails are polished, the resumes are perfect, the proposals are structured and articulate. To filter for real thinking, I even created a job description that required candidates to answer a series of questions before I would interview them, and I expli
