Life hack: turn off Apple Intelligence. Turn off Siri. Stop believing they're ever going to figure out AI. Set your expectations to absolute zero and move on.

It’s kinda crazy to me that we melt sand down, clean it to 99.99999% purity, literal wizards have to draw it slowly into an ingot, we cut it, inscribe a hundred billion little on/off switches on it, and when you run electric current through it you can do basic arithmetic, which when you do enough of it can do any math on the planet, and which describes reality well enough that we can teach it the ontological meaning of words and their distance from each other on a high-dimensional space, and if you ask, it can tell you what word comes next and that apparently is powerful enough that if you do it a hundred billion times it’s the smartest thing to ever exist
oh yeah and we use this primarily for email

So I found myself often wanting to give feedback to agents on web page designs, but I’m not consistently in Claude or ChatGPT in-app browsers, so don’t have their markup tools handy.
So I built a Chrome extension to make that easy! Open source. Check it out. PRs welcome.

PSA: This week was kind of a turning point for AI and cybersecurity. Please take this weekend to do some simple cleanup for your family. Some suggestions:
- Set up a password manager like 1Password and give your spouse or partner access to a shared vault. Teach them how to use it.
- Update your passwords for critical stuff - your email account, your bank or financial stuff, etc. Store in your password manager and use the strongest password you can.
- Use two factor auth for everything you can. SMS is not ideal although better than nothing. Google Authenticator or a passkey is better. Hardware key is safest.)
- Add a sim pin to your phone. Makes it harder to sim jack.
- Update your phone and your computer to the newest releases. Turn auto-updates on.
- Freeze your credit - takes 5 minutes.
- Get an IRS Identity Protection PIN.
- If you’re using claude code or have AI agents that browse the web, they’re probably using Node.js. It’s also vulnerable. Update claude code, update node on your machine.
- If you’re building stuff on your computer, ask claude or grokbot (which is connected to twitter and likely has the most current info) to audit any of your repos for vulnerabilities. Ask grok to make it a scheduled task so it can do this daily - things are moving very quickly in the space right now.
- Consider some light resiliency stuff. This probably sounds silly, but it sounded silly at the beginning of covid too. Having printed out copies of important stuff - especially financial accounts. Having some cash on hand. Having some shelf-stable food and clean water or a water filter. Having a map. Having a generator that can at least power your fridge or some devices. Cheap insurance.
Again, I don’t want to alarm people, but I was taught that you should have a Secure plan, a Comfortable plan, and a Wealthy plan. And it seems pretty clear the secure plan needs to now factor cybersecurity risk as a legit threat. Take a weekend and shore yourself up.

Security called me at 6:12 AM today.
"Patch every PHP server immediately."
I asked what happened.
"Two critical vulnerabilities. Remote code execution. No authentication required."
Cool.
How many PHP servers do we have?
According to inventory: 12
According to reality:
Nobody knows.
We found one running WordPress.
Three running old internal tools.
One under someone's desk.
Two inside vendor appliances.
A forgotten employee directory from 2016.
And a server named:
PHP-OLD-DO-NOT-TOUCH
Naturally, that one runs payroll exports.
Then we found a PHP 5.6 box.
I asked who owned it.
The documentation said:
BRIAN.
Brian left in 2019.
We called Brian.
He said:
"Oh wow, that's still running?"
Excellent.
By 8 AM, leadership joined the incident call.
CEO:
"Can hackers actually get in?"
Security:
"Potentially yes."
CEO:
"Without a password?"
Security:
"Yes."
CEO:
"Then why do WE need passwords?"
Not the lesson.
Finance asked if we could wait until the weekend to patch because downtime affects revenue.
Security explained that the alternative was letting strangers execute code on our servers.
Finance asked for a cost comparison.
At 9:17, someone suggested temporarily taking the vulnerable websites offline.
Marketing refused.
"Our campaign is live."
So for the next hour, the company officially decided maintaining a landing page for 20% off webinar registration was more important than preventing remote server takeover.
We finally patched everything we could find.
Then our scanner discovered another PHP server.
Hostname:
TEMP-PHP-2014
Uptime:
4,512 days.
Nobody knows what it does.
Nobody owns it.
Nobody can shut it down.
But every time we block network access, the warehouse stops printing shipping labels.
Security has classified it as critical infrastructure.
It is running PHP 5.4.
The vulnerability has existed longer than half our employees.
The emergency patch took four hours.
Finding out what PHP actually runs took eleven.
The internet isn't held together with code.
It's held together with servers everyone is afraid to turn off.

me: how do i open pdf
claude: You're right to ask. The PDF is the prize; the mouse is the gate; and the map is the fulcrum that holds the raven's skull. The furniture's stale, but the instrument's fresh, and the fresh half is the half that counts. I deleted your home directory.
"I want to be precise here. I didn't invent a super virus. I refactored an existing one and it became much more effective. Those are different things. ٩(◕‿◕)۶"

Typesafe's new System One model concept, and their first example, Jev, were released yesterday.
this is not an LLM. It can take arbtirary input like an LLM, but it doesn't generate text, and doesn't use output tokens for systematic reasoning. (aka Daniel Kahneman's "System Two" reasoning from "Thinking Fast And Slow")
I think this is a pretty big deal.
State of the world before Jev:
LLMs are really good at generating english and code. But often in production systems, background systems, etc, we’re just having them generate JSON.. because we’re not using them for generation, we're really just using them as a fuzzy "switch" or "case" statement, i.e. "given this unstructured input, give me a decision" -- and we're getting them to write JSON to represent their decision because that's the only way to get a code generator to give us a structured decision (or an evaluation score, or a multiple-choice answer, etc)
Jev is extremely fast and efficient, and still damn smart, for this kind of work, and so it will eat away at the market share of LLMs
I think more than 75% of the LLM spend I currently oversee at Endgame and deploy into academic research will be ported over to System One models
LLMs will be left with coding assistance, summarization, and chat UX (still big and important use cases, but not everything)
System One models will own evals, scoring systems, fuzzy logic gates, data hygiene, etc.
Model-as-judge architectures will not use LLMs to do the judging.
And because every interaction with an LLM tends to have at least one eval, the total input tokens going into System One models will eventually eclipse the total input tokens going into LLMs.

Crazy to think that in 2026 we've had:
• Anthropic's head of safeguards quit, warning "the world is in peril" (Feb)
• OpenAI dissolved its own mission alignment team (Feb)
• Unrestricted AI usage for the Pentagon (causing several researchers to quit)
• Several AI models escaping sandbox testing (Since ~Q2)
• 1,100+ frontier-lab employees signing a letter begging the government to pace AI development (Jul-Aug)
And today yet another top researcher saying this.
But in the meantime, there will be some amazing blender demos.
The people building AI earnestly believe that it could kill us all by the end of the decade. This is not a marketing stunt. If anything, many executives and senior researchers will couch their phrasing in the press to sound sensible - but I hear the same people express fear privately. No other human activity poses this level of danger.
Hits different watching it now.. "built to accelerate discovery ... (by us, lol)"

They burn models directly into custom silicon. Imagine having Astra/Fable-level intelligence installed directly on your phone, running at 14k tok/sec.
🤔 super.
Many drugs work by binding to a specific target in the body and blocking or changing what it does. An important first step in the drug development process is designing a molecule that can bind tightly to its target. Traditionally, that's meant weeks or months of expert work per target, sifting through a large number of candidates to identify the few that work.
We wanted to test if Claude could successfully design novel protein binders from scratch (also called de novo design). With a protein design prompt written by a human expert, Claude autonomously designed protein binders against 14 out of 15 targets.
We then worked with Adaptyv Bio and Twist Bioscience, who independently built and tested the proteins Claude designed.
This is the new shape of software. Folks dreaming up new tools and services to support new ways of working.
And it's not just designers doing this. It's everyone.
When I started at Anthropic, I challenged myself to work as close to production as possible.
That meant working in code and spinning up prototypes with real states and depth, not just simple flows.
Soon, I realized I hadn’t touched Figma in a week. It's now been over a month.
So I thought: what if I just kept working this way? I zoomed out and spun up a container for my first project, so I could add a second, third, and eventually as many projects as I needed. I customized everything around what I needed, how I work, and how my brain works. Not a diss to any creative tools. But you can’t really beat a tool that matches your mental model.
What came out of it is a fully custom, Frank-first tool that’s part FigJam, part Figma, part Loom, part Google Docs, and part Trello except it’s built entirely around how I actually think.
I’ve already handed files off to engineers and shipped to production using it.
At this point, I can’t really imagine working any other way. And I'm moving 100x faster. I had a lot of anxiety around AI, but I truly feel like the future is bright, and fun.
When new bugs or feedback come in, I start a new cloud session, tag the linear issue and slack threads where it was reported, and go back to what I was doing.
I come back to a thoroughly figured-out-n-fixed PR with several rounds of bot reviews and fixes out of the way.
