The Argument Against AI Writing Is At Least 2,400 Years Old

Bret Stephens says never write with AI. Reid Hoffman says judge the work, not the tool. I'm with Reid, and the argument Stephens is making has been made about every writing technology we've ever invented.

What the Actual Fuck, Carl

I finished book eight of Dungeon Crawler Carl. It took me eight months to get through the series and I savored every one of them. Matt Dinniman is doing something extraordinary.

Zero Knowledge: Twenty Chapters In

A month ago I opened up Zero Knowledge, the crypto-thriller I'm co-writing with my AI. There are twenty chapters now, a cast page, a plate for every chapter, and a pile of reader notes I'm grateful for.

Read Zero Knowledge As I Write It

Zero Knowledge, the crypto-thriller I'm co-writing with my AI, now has a home at zeroknowledge.ink. Six chapters are live, you can mark up any sentence, and the whole thing is being built in the open.

RIP Josh Baer

Josh Baer, the founder and CEO of Capital Factory and the godfather of Austin's startup scene, died last night in a plane crash. He was my friend and I'm sad today.

Does the Rule of 40 Work for Hardware?

I've written about the Rule of 40 since 2015, and it's now gospel in SaaS. Does it mean anything for a company that makes physical things? Yes - but you have to read the curve, not the snapshot.

Writing a Novel with Phin Argofy

I've written nine non-fiction books and have no idea if I can write a novel. I'm trying anyway: a crypto-thriller called Zero Knowledge, co-written with my AI, Phin Argofy.

Phil Weiser For Colorado Governor

I'm good friends with Phil Weiser and Michael Bennet, and I think the world of both. Colorado wins either way. Here's why I think Phil is the right fit for the next four years.

The Premise: The Lead User and the Machines That Build Machines

Eric von Hippel taught me that innovation comes from users, not manufacturers. My premise: all future end-user software innovation will come from the user, and the machines will build it.

It's Summertime

A summer weekend in Aspen - close friends, a gloriously bad movie, running again, and Phin Argofy quietly going autonomous in the work cave.

How to Rule the World

I read Theo Baker's How to Rule the World in the last 24 hours. It works on a lot of levels at once - memoir, investigation, a study in how power dismisses inconvenient reporting, and a master class in what not to do at the board level.

The Cognitive Sport of Building Startups

Meru Health launched Advanced this month - the first integrated mental and physical health program built for founders. Why it matters, and why I invested.

Burn Bright, Not Out

For the month of May, I'm matching donations to the Kabila Founder Mental Health Fund. Plus a free chapter from a new book on founder mental health in tech startups.

The River

After 5 million years, the Colorado River fights to survive — and an unlikely ensemble of people across the basin must defend their way of life while reckoning with the choices that brought it to the brink.

Give First, Build Right with Eric Ries

On April 29 at 10am PT, Eric Ries and I are doing a free fireside chat for startup communities. We're going to talk about the lessons we've learned as founders, investors, and advisors - and the books we've each just put into the world.

I Built a Plugin Because Anthropic Won't Stop Shipping

Claude Code ships updates daily. My config breaks weekly. So I wrote a plugin that cross-references release notes against my setup.

Nothing New to See Here

A founder told me seasoned engineers keep saying AI-built software is not possible. I've heard this exact story before - about the Internet, the Web, SaaS, and mobile.

Opt-Out Is Not Consent

GitHub announced they'll use Copilot interaction data to train AI models by default. The right answer is opt-in. Microsoft can afford to ask.

Quality

I first read Zen and the Art of Motorcycle Maintenance in college. I've read it at least a half dozen times since. Ted Gioia just published a piece about the real story behind the book.

Three Books for the Next Phase

I read three books yesterday that have nothing to do with each other on the surface. One is about founder mental health. Another is about monks who hike. The third is about quitting your job and figuring out what comes next.
