out of all the writing I’ve encountered about raising little kids, I think this is the piece I’m most grateful to have read

This calls the viability of the entire internet into question. If simply using any online software requires paying enormous taxes to Anthropic and OpenAI in the form of huge cyber bills, will it still be worth it to use all the software we use now?
some quick thoughts on frontier labs and cybersecurity 1) two critical vulnerabilities were discovered in php that allow for remote code execution; the first was reported on august 11 2) it seems now humans just weren’t devoting so many resources to finding vulnerabilities, and perhaps weren’t that good at it in the grand scheme of things 3) i think open-source software is going to have to change: maintaining it will increasingly become the responsibility of frontier models and frontier labs 4) no one else will have such advance access to frontier models or be able to spend as much on tokens as the labs themselves 5) so, it makes sense for frontier labs to scan and patch open-source software, especially the code their coding agents use to build software 6) one issue, though, is that open-source projects often have difficult governance structures, so i can imagine a world where frontier labs just fork these projects 7) build and maintain their own versions, making fixes, improving performance, adding features, etc and then train their models to use them by default 8) i can also see a world, very soon, where ~all software at a company has a claude or codex instance running 24/7 that watches over it (like the anthropic superfans) 9) the agent watches an anthropic or openai feed and, when a vulnerability is found, immediately kicks off a full migration to the new version 10) or otherwise refactors the codebase, changes the infrastructure, ports capabilities, etc... to mitigate the vulnerability 11) this will happen automatically, without a human in the loop; engineers will just come in the next morning and see what happened 12) this is part of what it means for coding agents to increasingly own software, and for labs to become responsible for the software supply chain 13) at some level, i think this just becomes the enterprise expectation when they are paying millions for coding agents / the agents are making arch choices 14) it is a very exciting time to be at a frontier lab and think through what this product offering should look like and how it should be sold to enterprise clients

In another timeline it could be a big hedge fund guy, someone with rich ancestors, or simply the guy with the biggest army. Seems much better this way.

Moderaterna vill att Sverige ska vara Europas Silicon Valley. Därför presenterar statsminister Ulf Kristersson och jag idag i Dagens industri två nya moderata vallöften för att cementera Sverige som Europas ledande technation: • Ett världsledande program för personaloptioner • Se över visumregler, som kan innebära ett riktat tech- och talangvisum Sverige har länge legat allra längst fram, med framstående innovationer, hårt arbetande entreprenörer och startups. Det ska vi vara stolta över. Men vi kan inte luta oss tillbaka om vi vill vara bäst också i framtiden. På min techturné under våren har samma tydliga budskap kommit från alla de bolag jag träffat: Sverige måste bli bättre på att attrahera världsledande kompetens och få fler talanger att stanna här och bygga framtidens företag. Systemet för personaloptioner måste göras om, så att snabbväxande techbolag inte växer ur dem på kort tid. Regler för visum behöver ses över för att bättre svara upp mot techbranschens behov. Det måste gå snabbare och vara enklare. Sverige ska vara den självklara destinationen för spetskompetens inom tech. Sverige ska inte bara ha en stark techscen. Vi ska vara bäst, i dag och i morgon. Moderaterna är redo att göra de reformer som krävs för att nå dit. Vi ska vara Europas Silicon Valley. En plats där företag vill starta, skala och även stanna.

If you're thinking about using gen-AI to "write" books, this 🧵 is for you. I’m a highly experienced editor who’s been in the biz a long time. Recently I’ve had manuscripts come to me where the author has used gen-AI – not for writing, I’ve been assured, but for

some random ai thoughts: - for code, i went from 80/20 claude/gpt to 80/20 gpt/claude in <3 months. surprised by this tbh, and interested to see where the split is at in another 3mo. - claude still mogs gpt for non-coding agent stuff. codex feels like an engineer (which is great for coding!), whereas claude still feels like a general purpose coworker. gpt still lacks that coworker magic - i’m pretty meh on opus 4.7. my experience hasn’t been *bad*, but it certainly hasn’t been good. sideways if anything. - anthropic has got to figure out the compute thing. you can feel it as a user. vibes are all out of whack bc of it. my opinions above are all likely downstream of this. it’s an issue. - anthropic labs continues to be the goat of ai product. claude design is another hit. it’s fantastic. idk why it’s not talked about more? a+ - updated claude code app is great. i finally switched out of the terminal for it. very well done. - how are people STILL sleeping on the claude agent sdk? i feel like i’m going insane. - gpt 5.5 is incredible. the level to which i trust it for engineering is amazing. if i could only have one model rn, it would be this one just bc of strong need for the coding use case. - codex team is killing it. app has been the gold standard since 5.3 release (buuut i credit conductor team for the ui innovation that everyone is using now). though i could do with a little less passive aggressive shots at ant from the codex team. TARS, dial up class by 30%. it’s a long race guys haha - i uninstalled cursor this month and am now back to vs code for my ide. composer just can’t hang with claude/gpt, and the product feels a bit all over the place. pretty stoked about the xai thing though, because their team is absolutely stacked and i’m excited to see what they might be able to do with that compute. codex and claude code are t1, cursor is t2. i would love if this deal got xai/cursor to t1 for a real trio there. - gemini…? seems like this is 2-3 models now where the model seems like a great release and then nobody ever uses it? i’m bullish google/deepmind but weird it hasn’t translated to product use in any form. kinda disappointed still - no open source models have hit the opus 4.5 level. was hopeful the new deepseek would get there, but nope. good oss agents will have to wait a few more months it would seem…

The victory of the opposition in Hungary yesterday, like the Polish election in 2023, is a victory for democracy, not just in Europe but around the world. Most of all, it’s a testament to the resilience and determination of the Hungarian people – and a reminder to all of us to keep striving for fairness, equality and the rule of law.

Another week on the road meeting with a couple dozen IT and AI leaders from large enterprises across banking, media, retail, healthcare, consulting, tech, and sports, to discuss agents in the enterprise. Some quick takeaways: * Clear that we’re moving from chat era of AI to agents that use tools, process data, and start to execute real work in the enterprise. Complementing this, enterprises are often evolving from “let a thousand flowers bloom” approach to adoption to targeted automation efforts applied to specific areas of work and workflow. * Change management still will remain one of the biggest topics for enterprises. Most workflows aren’t setup to just drop agents directly in, and enterprises will need a ton of help to drive these efforts (both internally and from partners). One company has a head of AI in every business unit that roles up to a central team, just to keep all the functions coordinated. * Tokenmaxxing! Most companies operate with very strict OpEx budgets get locked in for the year ahead, so they’re going through very real trade-off discussions right now on how to budget for tokens. One company recently had an idea for a “shark tank” style way of pitching for compute budget. Others are trying to figure out how to ration compute to the best use-cases internally through some hierarchy of needs (my words not theirs). * Fixing fragmented and legacy systems remain a huge priority right now. Most enterprises are dealing with decades of either on-prem systems or systems they moved to the cloud but that still haven’t been modernized in any meaningful way. This means agents can’t easily tap into these data sources in a unified way yet, so companies are focused on how they modernize these. * Most companies are *not* talking about replacing jobs due to agents. The major use-cases for agents are things that the company wasn’t able to do before or couldn’t prioritize. Software upgrades, automating back office processes that were constraining other workflows, processing large amounts of documents to get new business or client insights, and so on. More emphasis on ways to make money vs. cut costs. * Headless software dominated my conversations. Enterprises need to be able to ensure all of their software works across any set of agents they choose. They will kick out vendors that don’t make this technically or economically easy. * Clear sense that it can be hard to standardize on anything right now given how fast things are moving. Blessing and a curse of the innovation curve right now - no one wants to get stuck in a paradigm that locks them into the wrong architecture. One other result of this is that companies realize they’re in a multi-agent world, which means that interoperability becomes paramount across systems. * Unanimous sense that everyone is working more than ever before. AI is not causing anyone to do less work right now, and similar to Silicon Valley people feel their teams are the busiest they’ve ever been. One final meta observation not called out explicitly. It seems that despite Silicon Valley’s sense that AI has made hard things easy, the most powerful ways to use agents is more “technical” than prior eras of software. Skills, MCP, CLIs, etc. may be simple concepts for tech, but in the real world these are all esoteric concepts that will require technical people to help bring to life in the enterprise. This both means diffusion will take real work and time, but also everyone’s estimation of engineering jobs is totally off. Engineers may not be “writing” software, but they will certainly be the ones to setup and operate the systems that actually automate most work in the enterprise.

Data analytics just changed and most BI tools should be worried We spent years at Voi getting our structured data in order. Snowflake as warehouse, Steep for visualization, semantic layer defining what metrics actually mean Then we plugged MCPs directly into the warehouse and semantic layer Now I can query anything I should have access to in natural language from Claude (or other similar tool) We built a company plugin in Cowork so everyone can do it. Not just me, not just data people, but everyone We added our tone of voice and brand guidelines. Output format is whatever you want. The code gets written for you And here's where it gets wild: layer in external sources through scraping and computer use. You now have an all-seeing AI analyst sitting next to you Real example I ran: "Compare ride distance vs ride duration for Berlin, June 2025 vs Y-o-Y. Add weather impact analysis. Suggest visual format." It just... did it, in 15 min Half the value prop of traditional BI tools just evaporated. What am I missing? – at Stockholm, Sweden
