Head of Claude Code: "The model changes so often that I sometimes get stuck in this old way of thinking. I find that new people on the team do stuff in a more AGI forward way than I do. You have to transport yourself to the current moment and... show more

The single biggest mistake people make in relationship building. They do not follow up. And they do not follow up because they do not do it the night of the dinner/event/drinks. Every time I go to an event, in the car, on the way home, I email every person I met that night that I want to progress a conversation with. 99% of people do not do this. They say, I will do it tomorrow and they never do. That said, at the end of an evening, in the back of an Uber, I do not want to type 10 emails. Wispr Flow for the win. Do all of them in sub like 10 mins. The way you follow up is the way you are remembered. PS. This was written with Wispr Flow from a walk in London! Try Wispr Flow yourself at

Boris Cherny (Creator of Claude Code): "The one technical book I would recommend to everyone that has had the greatest impact on me as an engineer is functional programming in Scala. You're probably never going to use Scala day today, but the way it teaches you to think about coding problems is just such a change from the way that most people were in coding, either practically or in school. It's just. It's incredible. It's going to completely change the way that you code now. I think in types, when I code, the thing that matters in your code the most is the type signatures. This is more important than the code itself." Boris Cherny

Lando: “In a way I wanted to keep number 4 because I'm just happy with that and it goes well with my logo. So that's how straightforward I am. But I will go with number 1. Because I have to. I have to. It could be my only opportunity in my life that I get to do such a thing. Not many people in the world get to do that kind of thing. And it's not for me. It's just for my mechanics. This is for my engineers. It's the fact that they get to run with the number 1 on the car. And I think it'll mean a lot more to them than it does to me as a number. And for me, that's a lot more important.”

Anthropic CEO Dario Amodei on Open-Source AI Models. "I don't think open source works the same way in AI that it has worked in other areas. Primarily because with open source you can see the source code of the model. Here we can't see inside the model, it's often called open weights instead of open source to kind of distinguish that. But a lot of the benefits, which is that many people can work on it and that it's kind of additive, don't quite work in the same way. So I've actually always seen it as a red herring. When I see a new model come out I don't care whether it's open source or not. If we talk about Deep Seek I don't think it mattered that Deep Seek is open source. I think I ask, is it a good model? Is it better than us at the things that matter? That's the only thing that I care about. It actually doesn't matter either way. Because ultimately you have to host it on the cloud. The people who host it on the cloud do inference. These are big models, they're hard to do inference on. When I think about competition I think about which models are good at the tasks that we do. I think open source is actually a red herring. It's not free. You have to run it on inference and someone has to make it fast on inference." --- From 'Alex Kantrowitz' YT channel

I've started a nonprofit, GuardRailNow, and I need your help. Our approach is unique: I do not come from tech. I cannot write code. I do not live in SF. I am not an EA. I am not a rationalist. I have never been to Silicon Valley. I'm a dad in Baltimore talking about AI extinction risk to other people like me. AI Safety loves selling Bibles outside churches, preaching to the choir. It's easy to talk to people who are like you. It's much harder to talk with people who are very different than you. So why would AI safety people, who are from/in the SF bubble, who use EA/rationalist speech patterns and thought, think they are in any way the right people to bring the message to everyone else?? They are not. If AI Safety wants to get regular people on their side here's a hint: get out of the way. You are the problem. You do not act or talk or think in ways that connect with everyone else. I'm sorry if that sounds harsh. But our lives are on the line. Get over it and pass the ball to people like me.

The challenge you get in 2025 is that many women have only achieved things because of their looks and not because they are skilled. They go through life thinking that they are talented when really they are just women. This is especially prevalent in media - I have managed both male and female YouTube channels and I can tell you without a shadow of a doubt that men have to do way more to get half the followers women get! The lack of humility from commentators that have the easiest jobs in the world amazes me!

I think I just realized my childhood dreams🥲 BrickCraft can convert text, image or model to a Lego model in minutes. Many of you complained in my last post that the model was completely solid and not hollow, so I fixed that, along with adding support for textured models!

“I know that I won't have this moment again in this exact same way. I think the success of Brat and the success of the marketing of Brat is also in ways a curse. I'm not going to be able to market my next album in the same way. I'll pivot, but whatever I do next will be compared. Even if the music is completely different, the scale, the way it's rolled out, the level of conversation, I'm aware that whatever comes next, this [Brat] is kind of the albatross.”

Old software engineering patterns are coming back because of coding agents. Dax Raad(dax), co-founder of AI coding agent OpenCode, on why DDD is becoming more relevant and less painful: “I think it's the same problem as always, which is how do you make code bases that are easy to work in, scalable, that can flex to new requirements. A lot of the old patterns for me are coming back. We've always been a big domain-driven design company. We did it in a very light way. We're now doing it in a much heavier way because we find that these, kind of boring, enterprisey patterns end up being pretty useful because you have a bunch of idiots on your team now. Coding agents are a bunch of idiots. They are going to work 24/7 and they're going to ship a lot of stuff so you need way more guardrails than you used to. What's nice is some of these old patterns we hated because they were very verbose, they produced reliable code that was modular and safe but they were very verbose and annoying to type out… you're not typing it out anymore. Now you can get the benefits of these patterns without the downsides."

So I try not to get like... because I feel like a lot of problems often stem from me feeling like some way and then like demonizing that feeling when when it's not something that you should like demonize Yeah, so imposter syndrome, I get it But I also try to tell myself it's just a way of humbling myself, I guess It can be crippling though, sometimes And the way out of it is by keeping people that I respect and admire around me So that when they tell me that they trust me then I can trust them Because when I don't trust myself, I trust those people And thankfully, I have four of those people in my life, in my team And' then I have a bunch of staff who I feel the same way about

We asked rahul about the global reach of ChatGPT and the emphasis on personality in AI models. "When you want to get to the one to like the remaining 90% of the users, do you want a model that thinks for longer? You want more personality?" "They definitely leaned in on personality, which I think is interesting." "It's kind of different than a (social media) feed in some ways because you have this person you talk to. It's like a relationship and then it just switches up on how it talks to you."

Insane: 90-95% of Claude Code is now written by Claude Code. I asked Mike Krieger (Anthropic's CPO) what changes when so much of your code is written by AI? His answer: The bottleneck moves from coding/design to: 1. Upstream: aligning the team around what to build. 2. Downstream: the PR merge queue, reviewing and merging all of the new code into production. Anthropic is where other product teams will be in a year or two, so it's important we pay attention. "I would expect that a year from now, the way that we are conceiving of building and shipping software changes a lot. Because it's gonna be very painful to do it the current way."

Mully on the Bulls: "There is not a reasonable direction out of the NBA purgatory they are in. And I would say it's closer to hell than purgatory. They are stuck. They are absolutely stuck in the middle with very little (way) out. There's not a lot of hope. It's deflating."

Goldman Sachs CEO David Solomon on the open question of agentic investing: "Models work on the facts that are available." "Sometimes the biggest changes in the way you have to think about investing in a portfolio comes from things that are completely new and unexpected." "It can't be something from the past." "There are a handful of people who have so outperformed as investors over a long period of time, but... generally speaking, people underperform." "And so if the models are based on the information that the people are underperforming all have, it's going to be interesting to see whether something different comes out of it." David Solomon with David Haber and benahorowitz.eth

The old model isn't going to be there for young people anymore, that being: "Get good grades, go to work for a company, get a paycheck, keep your head down, put it into a 401k." I don't think that model works anymore. Circumstances have changed, we're at the end of a monetary regime that got kicked off in 1971, and it's drawing to some sort of a conclusion. Full interview:

NEW🚨: Vice President JD Vance just announced he is withholding Medicaid reimbursement from MN during the fraud investigation. I asked him if this should be viewed as a playbook for fighting fraud in other states. "I think you can, certainly. There are certain things that we're doing in Minneapolis and Minn. that I'm not gonna be able to do in other parts of the country, because the fraud is gonna be different in each place. But yeah, I get this basic model of saying to people, 'Hey, you get a massive amount of money to provide a service to people.' Did you actually provide that service?" The Daily Signal
