ChatGPT saved me from a USPTO scam. I was ready to respond to a message from the USPTO when I pasted it into ChatGPT to ensure I answered it the right way.

I'll need AGI to untangle the mess of notes and documents I have scattered over Notion, OneNote, Notes, GitHub, GDrive, OneDrive, Dropbox, and email.

This comment on the “South Korea Is Over” video on YouTube is brutally honest and clearly articulates the sentiment of a generation. I wish that other nations would take note and act. It's not too late for the US. We have to ensure women don't feel hopeless and helpless about the future.

One big difference between Claude Code and Codex is that Claude provides information in numbered lists, while Codex prefers bullet points. Numbered lists are better.

That’s why I’m so optimistic about the future of software engineers. One vibe coder created work for three software engineers for at least three months!

This actually reduces my level of anxiety.
I guess investors finally figured out the AI boom is actually an AI bubble. 😬

Gemini 3 seems impressive. I really want to try it to work on coding tasks. I've got Claude Code working so well right now that I wonder how much effort it will take for me to learn how to control Gemini.

Figma stock is 69% below its peak. Adobe is down 26% YTD. On the flip side, startups for developers, such as Cursor, and product managers such as Lovable, Gamma, v0 are exploding in adoption. This reflects my view of the future of these careers. ⬆️ Developers ⬆️ Product Managers ⬇️ Designers.

AI experiences today are 1:1 between a human and an LLM. Meta has embedded MetaAI on WhatsApp, but it's not useful. What OpenAI is doing is not useful either, but it will give them the lessons they need to bring it to productivity apps. That's where the true value is.

Finance guys have a hard time seeing depreciating assets for more than a line in Excel. The whole “AI Bubble/CAPEX/Depreciation math” is lame. BigTech has a build-out with unclear demand, but the GPUs won't stop working after 3-5 years.

This is a first from Claude. It told me it'll take 21-29 hours to implement this feature. I don't buy it. I think it'll be 4-6h. I'll report back EOD.

It takes 10-15 years for software “fads” to die down or to find their proper niche. Serverless, NoSQL, microservices, GraphQL, functional programming, Kubernetes, blockchain… 🧵

After 11 months, I sold nearly 1,000 copies of my book, and I have only 21 ratings on Amazon. It's easier to get someone to buy the book than to get them to leave a rating.

I have an optimistic view that in 2-3 years, Apple/Google + state governments will figure out a driver license system on phones, so I don't have to carry my wallet anymore. And luckily, in another 10 years, we'll be able to travel internationally without a passport! Just a phone and a face.

Financial advice online is useless and often harmful. There's little to no segmentation and certainly no personalization. The socioeconomic differences combined with each person's unique needs, goals, and knowledge levels make it impossible to generalize.

I feel vindicated in my yearly observation after each Apple announcement that people don't want a thinner phone, they want longer lasting battery.

Think of a big company as a city full of diverse neighborhoods. A person who lives in one neighborhood will have a unique experience from someone in another. One person on one team at a big tech company doesn't represent the full spectrum of experiences and responsibilities for that role.

I've been unable to log in to my Webflow account for a week now. I tried everything. It worked on Safari, but stopped working on Chrome (even on a new profile). ChatGPT gave me a bunch of suggestions, and this one, unexpectedly, worked! Posting it here in case it helps someone.

We don't know how to use LLMs for coding yet. People are throwing spaghetti at the wall and seeing what sticks. Many abandon after a few tries because it doesn't match their expectations. The LLM coding tools are less than two years old. 🧵
