To add insult to injury, now LinkedIn is hiding comments with links from the post author!
LinkedIn/Twitter/Threads shows posts with links to fewer people. The “standard” became to share the link in the comments so you reach *your* audience and people click the link in the comment.

Stop saying “knowledge worker” to refer to professionals who work from an office. Instead, say “information worker.” Dentists, plumbers, and teachers require substantial knowledge to perform their work.

Still on the theme of “AI will replace SaaS,” I wrote this post 8 years ago, and it's more relevant now than ever.

Remember when everyone learned how to bake bread during COVID? “AI will replace SaaS” is the new just-because-you-can-doesn't-mean-you-should.

I've been paying for ChatGPT for over two years, and it represented 99% of my LLM usage until four months ago. Now, 100% of my coding and 90% of my writing have shifted to Claude, and 50% of my research has shifted to Gemini. I still use ChatGPT for lifestyle questions (cooking, travel, finance...)
Internal memo: OpenAI CEO Sam Altman declares a "code red" to shift more resources into improving ChatGPT amid rising competition, delaying other plans like ads (The Information)

Twice last week I've seen founders proudly announce their new startup by telling people how hard they'd been working on it without explaining what they do, what problem it solves, or who it's for.

This is “Modern” medicine:
Mid-80s: GLP-1 discovered
2005: Approved by FDA for diabetes
2014: Approved for weight loss
2025: Recommended by the WHO
20??: Accepted by most doctors.
This pace of innovation is unacceptable nowadays.

Corporations paying their fair share of taxes is an important topic. But I'm really bothered by Metlife not being between Tesla and T-Mobile.
What do these corporations have in common?
Netflix
Ford
Tesla
T-Mobile
Duke Energy
DISH Network
Metlife
Dominion Energy
United States Steel
In recent years, they all paid their execs more than they paid in taxes.
This is what a corporate-rigged system looks like.

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.

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.
