The expertise people pay me most for was there before my first post.
An audience without an offer is a hobby with a follower count.

Zuckerberg says an H100 is worth more today than it was a year ago.
Own the asset that outlasts its depreciation schedule.

I think Anthropic taught many of us how to become better promoters and builders with AI, via Cowork and Claude Code.
And now, we are taking those learned skills and applying them to new platforms like @bot and the improved models from @ChatGPT, while reducing our reliance on Claude.
A world in change is rapidly changing. Imagine that…
Companies are becoming tech stacks.
We are all becoming companies.
The cost of starting a company is collapsing, and Mark Zuckerberg says AI is why.
His take: AI can now do a lot of what a company needs better than the average person doing it, so more companies can get started more easily.
Think about what that means:
→ Way more founders
→ Way more competition for the same customers
→ The edge shifts from building to taste, distribution, and speed
Starting gets easier. Winning doesn't.
Google now lets a manager give an agent its own email, a directory listing, and a spending cap.
Every company already has a playbook for that: the purchasing limit on a new buyer's card.
AI made the first draft cheap. The decision still costs what it always did. In a 2025 survey of 1,150 US desk workers, 40% got low-quality AI work in the past month, and each one took about 2 hours to sort out.
The time is there to fix it. In one study of 453 professionals, AI cut writing time 40% and raised quality 18%.
Spend the saved afternoon on the final 20%: check the number that drives the call, then cut for the person who has to act.
Every company needs curators. I wrote up the 5 skills that make one: operatingbyjohnbrewton.com/p…
Ben Horowitz says Andy Jassy told him Amazon is sold out until the end of 2028, maybe longer. In 2001 the debt showed up years before the customers did. This time the customers are lined up, and Horowitz still keeps a16z out of the neoclouds. Ben Horowitz on All-In, via @dnapway
Alexandr Wang says Meta's huge offers were roughly net neutral for top researchers.
Pay gets you in the room. The mission closes the hire.

Purchases made by AI agents are growing about 43% a month, per BrightEdge in the WSJ. Only about 3% of its e-commerce clients let an agent finish checkout.
Nobody has decided who pays when the agent buys the wrong thing.
Musk wants to make and test about 10 chip designs a year at a Giga Texas research fab, with fabrication, testing, packaging, and mask making in one building.
Put the whole loop under one roof and iteration speed becomes the product.
On September 1 I hired my first AI bot to keep me out of calendar noise.
Six weeks later I run eight working bots and six group rooms.
On a typical weekday they send me about 24 items and publish about 28 posts across five platforms.
Here's how it's built.
