Building and launching a product in one month. Worth it? How a minor itch led me down the rabbit hole of building and launching a product in an unsexy space. How I turned that into an experiment and my first observations on the results.

I've spent the best part of February doing an experiment.

It all started with a need and ended up building and launching a full product.

I turned it into an experiment to test the "powers" of AI-assisted coding tools.

The whole experience is told here: rush.mn/mqDMNB

I am a luddite and to me there is a lot of joy in technology. In technology that we deploy for all our wellbeing. Solar panels and vaccines, high-speed rail and wikipedia.

But they joy stems from the feeling of being able to be part of humanity in an embedded, meaningful way. Not from buying shit.

Five takeaways from an unhinged AI discourse What's behind the feverish AI discourse? Who thinks "AI is fake"? Is "the left" wrong to dismiss AI? Is that even what's happening? What's really going on with AI in 2026.

The AI discourse has been particularly unhinged lately. Here are five things I think are behind it:

Just to clarify, is it OK if I join in during the call even though I'm not technically a journalist but just someone who writes online about technology and its implications?

Technofascism Survival Guide Technofascism is here. From the Black Panthers to Anonymous to Julian Assange, what can we learn and how can we resist?

You are in time to do the same.

Support independent writers, especially when they talk about such a pervasive and devastating topic.

Looking forward to seeing my name on it @stopgenai.com !

Let me be clear, as quick misinterpretations are easy.

I am not blaming the process. I love write-intensive. I do write a lot myself.

The problem is with the expectations I'm setting on myself for going through the process, which inevitably leads to procrastination.

Oxide is at the top of the list of companies I'd like to apply to.

I respect them so much that I want to do the writing-heavy process very carefully.

Which means I'm constantly procrastinating because I never have the time I feel it deserves.

Am I the only one?

Help @bcantrill.bsky.social!

With the awful WaPo layoffs and the state of journalism more broadly, if it's useful for any writers and reporters considering going indy, @molly.wiki, @xoxogossipgita.bsky.social of Aftermath, @jasonkoebler.bsky.social of 404 Media, @edzitron.com and me will do a little workshop next week.

OK, I'll stop here.

Thanks, added to the list.

I'm currently going through Empire of AI by @karenhao.bsky.social , which I find to be a perfect companion for the AI Con.

Does any rigorous book on the "opposite camp" even exist?
I mean something better than "Abundance" or "The future is faster than you think"

More than welcome, and hopefully I can convince a few more people to read it :)

And then who knows, one day I might find a good enough reason to convince you to invite me to your podcast

They're both amazing in the sens that

1. Everyone should read them
2. They're sadly very accurate.
3. They share a common theme of resistance against the dominant techno-political fascist structures in today's world

I hope that more people will pick them up after reading the review

πŸ“š Books I read in January 2026 Two great books contended for the highlight of the month, but eventually I had to pick one. Besides those, a couple of fiction books worth reading completed the list for January.

I just posted the latest issue of "the books I read last month".

In January I got the pleasure of picking up both The AI Con by @emilymbender.bsky.social and @alexhanna.bsky.social, as well as On Tyranny by @timothysnyder.bsky.social

Both amazing reads.

Sure, but revenues can be more easily manipulated through selling at a loss in a race to the bottom against competitors (food delivery, anyone?).

They're a promise you might turn profitable in the future.

Not a guarantee.

See OpenAI, Anthropic, CoreWeave, etc

Ask them to show the 100x, or even 10x, improvements in company results.

Not vanity metrics, but actual cash.

Not valuations, but actual cash.

Not revenues, but actual net profits.

I wrote this song on Saturday, recorded it yesterday and released it to you today in response to the state terror being visited on the city of Minneapolis. It’s dedicated to the people of Minneapolis, our innocent immigrant neighbors and in memory of Alex Pretti and Renee Good.

I was having the exact same reaction yesterday when I heard about this.

We're living in unprecedented times.

Not because of marvelous technological advancements.

Because of the rapid decay of human decency at scale.
