Analyzing an exported brokerage account to count yearly trading decisions

"I had this idea where we basically exported his brokerage account, and we put it in Claude, and we asked it over the last 12 years, how many decisions did you make a year?"

Running daily automated SEO guide creation and writing all code and web content

"I use extensively Codex and Claude... but I will say at this point, 99% of the stuff that is left to be done is Claude waking up every morning and then running the guide, and that's kind of it."

Rewriting and updating an old academic dissertation with current information

"So I had ChatGPT rewrite her dissertation that she wrote 20-something years ago, but everything is now current... She was like, 'This is amazing. What AI is this?' And I'm like, 'It's ChatGPT.'"

Fact-checking and research

"Oh my god, you kids have it good now. I love ChatGPT and Claude and so on. It's so much easier. You need to know how to interrogate the system."

Tim Ferriss

Writing long-form articles, such as an 8,000-word piece

"I used it for writing all weekend and it is without a doubt my favorite new writing model. It beats Astra, which was my previous favorite. It definitely beats Claude. It has an incredibly good feel for structuring information and I used it all weekend to wr..."

Medical research and turning interview transcripts into newsletter posts

"I think really pleasantly surprised by how good Gemini 4 did at doing medical research, answering the questions that I had... for something like medical questions, I actually do want something that's super well researched. And that combined with its improve..."

Running AI agents independently on local hardware for AI sovereignty

"OpenClaw is a vote on making agents that are independent. If you use OpenClaw with Neotron or Gemma, which is Google's open source product, you will be sovereign AI. In other words, the AI running on your Mac Studio with 256 gigs of RAM."

"This is Jim. Jim is our OpenClaw recruiter. It runs on effectively like a three-stage pipeline. We do use OpenClaw for this but the harness doesn't really matter as much as just the skills. I have this system that I call autopilot and basically what it does..."

In-flight internet

"I want to start by shaming publicly Delta for not adopting Starlink... how atrocious the internet coverage in the air on Delta flights was. Just do it already... just use Starlink. If there were a better system out there, use that. But Starlink is what huma..."

Looking up health and science information more efficiently than traditional web search

"For anything we've said today, you plug it into Perplexity, you get better than a search — and you don't have to wade through 10 different articles and the different perspectives and who wrote this and who funded this."

Improving sleep quality, especially managing body temperature fluctuations at night

"There's lots of brands like Eight Sleep. I would sell that to anybody. It is such an amazing game-changing product, and I've got no — apart from the fact that I use it and they pay on the show — I have no loyalty to them as a brand, but they rule. The produ..."

Cooling the bed during sleep to improve sleep quality and recovery

"Anyone that's not using an Eight Sleep, it's medieval. I understand they're expensive, but every single person that I've got to try it can't believe what life was like before they had a cool bed. There's other cheaper versions out there, I'm sure Eight Slee..."

Handling subscription monetization for apps built on Replit; abstracting payment setup complexity for non-technical builders

"We have this deep partnership with Stripe where we've abstracted away all of the complexity. The user doesn't have to go sign up for Stripe, do the KYC upfront, figure out what a plan is. All of that is taken care of — we set up a Stripe sandbox in the back..."

Online shopping for general goods with reliable delivery and returns

"My personal revealed preference is I would almost always want it from Amazon because I trust it's going to get there. I know where to go to look to see if it's on its way. I know where to go to process a return if I want to do that."

Ben Thompson

Brand awareness marketing and retail distribution channel for a beverage CPG brand

"We were 100% on Amazon from day one, which was a decision we made as a board to do that. And it was such a good decision, but you don't make a lot of money on Amazon as a beverage. We saw it as a great marketing tactic for awareness because it's in so many ..."

Primary mode of transportation in the Bay Area, replacing car ownership entirely

"In the Bay Area, I got rid of my car. So, I only do Waymo and autonomous driving. I don't drive. I'm done with it. I would certainly never go back. Never go back to driving a car. It's just archaic."

Jason Lemkin

Taking autonomous rides as a passenger

"I've taken Waymos before. They're also great."

Coding agents and AI-assisted development workflows internally at ClickHouse

"Our Anthropic spend is up 100 times from what it was at the beginning of the year. I sent an email to the company and the subject was 'the AI awakening' and I said I think we're moving too slowly and I'm not seeing the adoption of these coding applications ..."

Aaron Katz

Business logic automation, workflow automation, coding agents

"We're using OpenAI, using Anthropic. We're going to increasingly use open source models to save money... we don't today have a budget constraint on our Anthropic contract. I think we're spending like probably 5 million a year or something. Ramping pretty fa..."

"Nvidia remains our absolute priority partner. They have the Frontier chip. Our next big training run in the fall will be done on Rubin."

Communication device for kids before high school instead of a smartphone

"So, give them a flip phone or a phone watch, you know, like an Apple Watch. A lot of parents are telling me they're having good results there. So, that's the first norm."

Jonathan Hurst

Reviewing new Audio Intelligence features and health tracking capabilities

"This is the Series 12 on my wrist. It has the S11, it has the Secure Exclave. The feature is not live and when it does go live, it will be in beta."

Inference disaggregation partnership to increase total throughput

"We're doing disaggregation with AMD and with AWS, where you think about in the work of inference, is there a part that can be done by somebody else and is there a part that can be done by you. We're seeing similar numbers with AWS."

Andrew Feldman

Cloud infrastructure for SaaS application

"We had no idea about AWS as it relates to like app usage. So like our early day bills on AWS and like the first time we set up Snowflake were like crazy high."

Zach Cherin

Business logic automation, coding agents, workflow automation

"As long as I'm allowed to use OpenAI and Anthropic, then I don't mind at all. Like they deserve it. These things are just incredible, miraculous products. What I worry about is that they cut us off and then we can't use it anymore."

Ryan Petersen

AI agents for personal/business tasks

"I've become on team Sam and OpenAI recently with my agents as my agents have taken control of my life. I've changed my allegiances to some extent."

Finding obscure, out-of-stock, or out-of-print items that can't be found on Amazon

"I use eBay all the time and I've never used auction. eBay is really good for really obscure stuff — things that either aren't officially for sale, they're way out of stock, out of print, or totally obscure. If I can't find it on Amazon, I look on Alibaba, a..."

"Don't even bother spending money on any platform that's not Meta until you reach $100,000 a month and spend on Meta. Meta is still the best winner."

Cliff Weitzman

Paid advertising and marketing to reach different consumer segments

"And we even like went back and forth for a while like what do we do on Meta back then? It was still Instagram. And what we realized is even though the price was quite a bit higher and we weren't seeing the return, it was just a different consumer."

Stephen Ellsworth

Cost-efficient task execution in Cursor; near-free Google Sheets creation and general agent tasks

"DeepSeek V4 Flash is probably the most interesting because for certain tasks it is 105 times cheaper than Claude. I highly recommend trying these models. This model is 20 to 100 times cheaper depending on the task."

Riley Brown

AI assistant access while traveling in China

"When I'm in China for two weeks, it's DeepSeek and Gemini. Those are my friends. DeepSeek is intentionally crippled in China. It's not as good as it is here. It can't search the web and it is trained on different data as near as I can tell."
