There are many reasons to be watchful of AI. Some are concerned by its environmental impact, others by the ethical quandaries we'll be faced with because of it, or the economic effects of mass job displacement. Others still feel above the fray, convinced that whichever way the cards fall, it will somehow benefit them (and their privileges).
This newsletter is rarely a space for that kind of nuanced discussion, because I feel disproportionately positively affected by these technologies, so I can rarely speak from a place of negative impact. If you are self-employed, working in technology and knowledge products, and working in public, you have the most to gain from what these tools are already unlocking. Most people are not, and thus have much less to celebrate when it comes to measuring the effect AI might have on their lives.
Finding reasons to be hopeful was practically a requirement ahead of starting this weekly writing journey. I try to learn from the best practitioners out there, and share my findings from across different fields. If no individual has the full picture of AI, then your direction of learning matters less than your exposure to it. The more you use it, the more you learn, and the better you get at judging where it's worth spending more time. Generalizing for others is notoriously difficult, so instead my focus has been on broadly sharing what's working for me, which 90% of the time comes down to building better tools for myself.
I have explored different ways of sharing these coding skills with different groups and audiences in the past few years. I've done plenty of in-person workshops helping non-technical people learn the ropes of using LLMs to give shape to their ideas, and coached practitioners who, like myself, are maximizing their token burn toward hopefully useful apps and projects. Of everything I do, the workshops are the part I'd defend hardest. I can't do much about the asymmetry I opened with, but I can shrink the group of people who assume these tools aren't for them.
If this is something you are interested in, join our next public vibe coding starter session on August 17. This one is designed for people with no programming experience who want to go from idea to working prototype. We'll build a personal website.
Being watchful and being hands-on are not opposites. The people I'd most want scrutinizing these tools are the ones who have built something with them and know where the seams are.

Agentic programming in 2026 — @Valentin Ignatev

Kate Devlin, Professor of AI and Society at King's College London and author of Turned On: Science, Sex and Robots, argues the emotional bond with an AI companion is genuine on the human side even though most users know there's no sentience, and challenges the therapists who assert human-human relationships are superior without ever explaining why.
That's not an AI saying let's go to war. That's two people or two governments saying we don't agree on something. Let's send bombs to each other. So how can that be defined as a good relationship?
YC Head of Design Eve Bouffard walks through her AI-first workflow: living almost entirely in Conductor and paper.design's shaders, dictating features via Aqua instead of typing, and shipping sites like Paxel with dual human/machine versions plus a "send to an agent" feature-request form that opens a PR on submit.
It's a form that either where we can submit a bug report... And what's cool is that we literally made the CTA in the button say send to an agent because in the back end that's literally what happens.
Eve Bouffard, design lead at Y Combinator, argues that as models one-shot everything, the scarce resource becomes imagination, not execution; she demos "Eve Thoughts," a week of Slack stream-of-consciousness that Opus turned into a personal website, plus a "Shape of Minds" tool built in one morning to map the commonalities of history's spikiest thinkers. Riffs on Paul Graham's "live in the future and build what's missing."
Naps were very popular among the best minds. Um, they barely ate.
Langfuse growth engineer Annabell Schäfer ran a self-optimization loop (GPT-5 nano classifying arXiv papers, Claude Opus proposing prompt edits) and found the first iteration alone jumped accuracy from 68% to 78%, then plateaued near 80%. Her point: the loop works because paper classification has a clean right/wrong signal, and almost no real domain (healthcare, compliance) does. Langfuse makes the case that domain experts, not more tokens, define the target.
There's barely any deterministic yes-no target functions. In most cases you run the same evaluator and get a different result next time.

Cortex
The interesting thing about brain-machine work right now is how fast it has moved from the operating room to the earbud, which means the ethics can no longer trail the engineering. Cortex tracks cognitive interfaces, neural engineering, brain–machine systems, and human augmentation, and reading it in sequence makes one thing clear: the questions of who reads your mind, and who owns what they find, are arriving before most of us have thought about them. Some things worth exploring inside: Silent Speech Interfaces, Neural Data Encryption Standards, and Cognitive Liberty Frameworks. Share it with the person who thinks neural privacy is a problem for later.
