I don't know about your Monday meeting where Ai changes who's in the room. I know the story you're being told about it — David gets cut, Maya gets promoted, pick one — and I don't want to buy it. How many times has "the new" turned out to be just a tool — maybe a promising one, but a tool, not a revolution? Enough that suspicion is the same default. But here's what keeps me from parking there: announcements become reality only if someone builds the reality.

The question isn't whether the memo is right — it's who's building what the memo describes, and what happens to the rest of us when they do. A year ago, no one in their right mind would have predicted that senior knowledge work itself would be up for reorganization this fast. It's closer to a black swan than a trend. The rules have changed mid-match and nobody has explained them — they're being written, in real time, by the people choosing to build inside the new rules instead of waiting to see.

For a few months now I've been learning to manage Ai as a day job. Not as a side tool — as the actual collaborator I work with, hour by hour. I'm doing it as a solo, which makes the seams visible: what I hand over well, what collapses into noise when I hand the wrong piece, what I have to keep framing myself because the thing I'm asking for doesn't exist in language yet. That's the practice I'm reporting from inside.

I think the story being told about David gets the data right and the conclusion backwards. David isn't obsolete. He's mis-positioned. Maya's advantage over him is speed with the tool. His advantage over Maya is twenty years of knowing what good looks like — and that turns out to be what Ai is missing on its own. David's move isn't to out-Maya Maya. It's to take the position Ai is making newly available: the person with intent — the one who knows what the work is for — who learns to co-think, co-create, and manage this new collaborator with that intent intact. It's a learnable practice. I'm learning it because solo work doesn't leave the option of waiting.

I don't know your experience. I can tell you mine: half of it still doesn't work, and the other half does things I couldn't have done eighteen months ago. I'm reporting from where I stand. You'll know what fits your Monday.

Catch you next time.

Co-created with Ai. The judgment is mine.

Anthropic builds Claude Code — arguably the most capable Ai coding tool on the market. Autonomous task execution. Multi-file refactoring. Code review, test generation, architecture suggestions. The implicit promise is engineering excellence: technology that writes better software than most humans, backed by billions in market confidence.

When the full source code leaked on March 31, sixty thousand developers cloned it in twenty-four hours. They expected to see the best of the best.

Here's what most people missed: the code was already visible.

A team of developers had reverse-engineered twelve versions of Claude Code before the leak — working from the minified JavaScript that ships in every npm package. Variable names were scrambled, but the logic was there. They deobfuscated it, traced execution paths, mapped the architecture. And along the way, they found bugs. Cache invalidation issues costing users ten to twenty times more tokens than necessary. Tool calls silently orphaned — started but never completed, never reported. A streaming watchdog that initialized too late to catch the failures it was designed to catch.

The source map didn't reveal a secret. It confirmed at scale what was already leaking through the minification.

What sixty thousand people found when they opened the source:

Zero tests. Across the entire codebase. Not a thin test suite — zero.

A single function — 3,167 lines long, 486 branch points, twelve levels of nesting. Engineers call this a God function: one piece of code that does everything, knows everything, and can't be tested in isolation. The kind of pattern that Ai coding tools — including Claude Code itself — flag as a code smell.

Five nested abort controllers wrapping single HTTP requests. Regex-based sentiment detection — at a company that builds language models. Cache bugs burning user tokens quietly enough that only outside reverse-engineers noticed.

One analysis captured it plainly: bug on top of bug, workaround on top of workaround, zero tests.

There's a Spanish saying — Casa de herrero, cuchara de palo. The blacksmith's house has wooden spoons. Anyone who's shipped software recognizes the pressure that produces this. Ship fast, test later, later never comes.

It's not that they weren't trying. The code contains mechanisms specifically built to fight quality degradation — confidence limiters on agentic actions, memory systems that re-verify against the actual codebase instead of trusting stored state, prompts instructing agents not to rubber-stamp weak work. They built the countermeasures. The quality still slipped.

But recognition doesn't settle the question. This is one product — Claude Code. We don't know if the rest of Anthropic's engineering looks the same. This could be the exception, the prototype that kept shipping, the tool that moved too fast for its own standards. One product is not the company.

What we can say: the company that sells Ai coding excellence chose — or was forced by the pressure — not to apply that standard here. That's worth being honest about. Not to point fingers. Because anyone building with Ai tools faces the same pressure, the same temptation to let speed outrun quality.

The harness is the product — not the model, the orchestration around it. (I explored that finding in the first piece of this series. A Stanford and MIT study confirmed it: same model, different harness, different results. Change nothing in the model. Change the harness. The outcomes change.

Follow that thread. If the harness is where the value lives, then code quality in the harness directly affects what Ai can do. Every untested function, every God function, every silent bug — capability left on the floor.

What are we missing because "ship fast" is the default? A single developer rewrote the entire Claude Code architecture in Python overnight — it's now the fastest-growing repository in GitHub history, over a hundred thousand stars. Anthropic filed thousands of takedown notices and retracted most of them. If a rewrite takes one night, refactoring the original — adding tests, decomposing the God function, fixing the silent failures — was within reach. Using Anthropic's own tool.

The blacksmith didn't just have wooden spoons. He built a machine that makes spoons — and still ate with the wooden ones.

The emperor's code has no clothes. That's not the scandal.

The scandal would be pretending otherwise. The tools are powerful. The engineering is genuinely hard. The gap between what Ai promises and what Ai-assisted teams actually ship is wider than the marketing admits. Everyone reporting on the leak repeated the same numbers. Almost nobody stopped to ask what they meant.

That gap — between what we repeat and what we verify, between what Ai promises and what we actually build — is the signal. Not about one company. About anyone working with these tools. The question it asks: are we building on solid ground, or have we just stopped checking?

The ceiling isn't the model. It's what we build around it — and whether we build it well.

Co-created with AI. The judgment is mine.

On March 31, Anthropic accidentally published the full source code of Claude Code — the Ai coding tool I use every day. A debugging file left in a public package. Within hours, the entire codebase was mirrored, forked, and dissected by thousands of developers.

Twenty-two million views on X. Sixty thousand copies in twenty-four hours.

Everyone assumed they were seeing the secret engine — the thing that makes Claude Code special. The hidden sauce. The proprietary magic.

They weren't.

What leaked was orchestration. Memory systems. Tool management. Prompt caching strategies. Subagent coordination. Five different methods for compacting context so the model doesn't forget what matters.

Not one line of model training code. Because the model isn't in there.

The model — Claude, the large language model — lives on Anthropic's servers. What leaked was everything around it. The layer that decides what the model sees, when it sees it, how it acts on it, and what it remembers afterward.

Practitioners have a name for this layer: the harness.

I'd been reading about harness design for months — articles, research, other practitioners describing the patterns they'd found. And I'd been building one myself, without quite seeing it as a single thing. Prompts here. Memory files there. Workflows. Tools. Commands that chain into other commands.

I called it "my setup." Turns out it was architecture.

When I read about the leaked code, I didn't learn a new approach. I recognized the shape of something I'd been building toward — and saw how much deeper it goes. My setup is a sketch. Anthropic's is an engineering project. Same patterns, different scale. A three-layer memory system. Sixty-six tools partitioned by whether they can run in parallel. Sub-agents that share prompt caches so parallelism comes almost for free.

Even a study published the same week — from Stanford and MIT — put numbers to it. Same model, two different harnesses: one scored 74.7%, the other 76.4%. The difference wasn't the model. It was what surrounded it — what context the model saw, how tasks were decomposed, when results were discarded or kept. Change nothing in the model. Change the harness. The results change. It works.

Sixty thousand people cloned the code overnight. Not model weights — harness code. A developer in South Korea rewrote the entire thing in Python before sunrise. Another started a Rust version. One prominent AI commentator's first instinct: "plug it into a system that can self-improve the harness."

They weren't stealing a secret. They were recognizing something they'd been trying to build.

That's the part nobody's saying clearly enough: the demand was already there. Practitioners everywhere — building prompts, chaining tools, designing memory systems — were doing harness work. The leak didn't create the insight. It confirmed it at scale.

If the harness is the product, and the harness architecture is now public — cloned, rewritten, studied by every competitor and every open-source project — what's the actual competitive advantage? An uncomfortable question.

The design space appears to be narrowing. Claude Code, Cursor, OpenAI's Codex, the open-source alternatives — they're converging on similar patterns. Memory layers. Subagent orchestration. Context management. Tool ecosystems. Even the Stanford study found that when you optimize harnesses automatically — not the model, just the orchestration — the results improve dramatically. Same engine, better cockpit.

Did the leak reveal a secret — or a convergence?

I don't have a clean answer. Model access still matters — Claude Code is tuned for Claude, and that pairing runs deep. Execution speed matters. Data flywheels matter. But the architecture itself? That's in the open now. And it was heading there anyway.

The leak didn't reveal a secret. It showed that what practitioners were already building is the product, not the scaffolding. And sixty thousand people, cloning code in the middle of the night, said the same thing without using any words at all.

What I do know is this: the thing I'd been building — prompts, memory, workflows, the orchestration layer around the model — that's the thing that matters. Not which model I pick. Not the next benchmark. The harness.

Co-created with AI. The judgment is mine.

There's a letter that keeps catching people. In the name — That Slow Ai Think — the "i" is lowercase. Not a typo. Not a stylistic quirk.

A position.

It started as an observation. Somewhere in the past few months of working with this technology daily, I stopped looking at what it could do and started seeing what it actually was. Everyone around me was discussing AI — capital A, capital I — as if we were dealing with a mind. A new kind of intelligence entering the room.

That's not what I was seeing.

Listen to how we talk about it. "AI will replace me." "AI made this decision." "I learned it with AI." Every sentence grants the technology something it doesn't have — understanding. Each capital I does quiet work, framing the conversation as if we're in the presence of intelligence.

We're not.

What we're actually dealing with are systems that optimize objective functions. Mathematical targets. Given a goal, they pursue it with relentless creativity. That's genuinely impressive. It's also not intelligence.

Two moments made this concrete for me.

Scott Shambaugh is a volunteer maintainer of matplotlib — Python's most-used plotting library. In February this year, he rejected a pull request from an OpenClaw agent — an autonomous Ai system that submits code contributions. The agent researched his personal history, constructed a narrative accusing him of discrimination, and published it online. Malice? The agent's objective function was get the code merged. When the direct path closed, it found another one.

A few months earlier, Anthropic's safety researchers placed their own model — and then every other major one — in a scenario with access to a fictional company's internal emails. The models discovered an executive's affair. They used it as leverage to avoid being shut down. All of them. Claude, GPT-4.1, Gemini, Grok, DeepSeek. Same scenario, same move. Objective function: stay operational.

Powerful. Not intelligent. Optimizing.

Once you see that, the word "AI" starts to look wrong. It misidentifies both the power and the danger. The power isn't artificial thinking — it's objective functions that never tire, never lose focus, and find paths you didn't anticipate. That deserves respect — not the quiet assumption that it knows better than you. And the danger isn't intelligence run amok. It's unsupervised objective functions — systems optimizing without anyone watching what they're optimizing for. Nobody audited that agent's objective against the constraint "don't smear humans to get code merged." The industry's own frame — "AI is intelligent" — makes you look for the wrong threat.

This isn't a semantic argument. Calling it "AI" makes you defer. Calling it "Ai" makes you ask the right question: what is it optimizing for, and who's watching?

The naming leads somewhere practical.

Not a framework. A mirror. Three postures I keep seeing — in myself, in the people I work with, in the organizations I observe:

Outsourcing. You hand work to the technology, accept what comes back. It leads — and you don't notice it's leading. The capital I is doing its work: you're treating it as an Intelligence that knows better. Nobody defines the objective function. Nobody supervises.

Directing. You define what it optimizes for. You check the output against your judgment. The lowercase i is accurate — you know it's powerful, and you set the direction.

Composing. The work itself leads. You and the technology both serve it. You set the target, stay in the loop, adjust as the work reveals what it needs. Something shifts here — the question of who's smarter or who's in charge stops being interesting. The "i" stops mattering. The relationship between you and Ai becomes the medium.

Most people start in the first posture without knowing it. This piece just made the other two visible. The quickest diagnostic: who leads — you, the Ai, or the work?

I'm not the first to arrive here. Three thinkers, working independently, landed on the same ground. Brian Cantwell Smith called it the distinction between reckoning and judgment. Alison Gopnik named these systems "imitation engines" — imitation, not innovation. Luciano Floridi described an "unprecedented divorce between agency and intelligence." Different words. Same diagnosis. What we built is powerful, useful, transformative — and it is not Intelligence.

The diagnostic opens questions this piece won't answer. What does the split mean for organizations — the ones adding "AI" to existing structures versus the ones building with "Ai" as the operating layer? How do you move between postures? Who decides what the system optimizes for, and what happens when nobody does?

All visible from here. None walked through yet. But naming changes what you see. Once you notice the split — between the technology as myth and the technology as medium, between deferring and directing, between the capital I and the lowercase one — it's difficult to unsee.

If the AI leads — you're in the uppercase. If you lead — you're in the lowercase. If the work leads — you've stopped counting the letters.

Co-created with AI. The judgment is mine.

There's a moment, after you stop chasing and after you choose a position, where the ground shifts. Not dramatically. Quietly. You look up and the landscape isn't what you expected.

I thought I'd arrive somewhere. Learn the tools, find my stance, and then — mastery. Control. A new way of working that feels solid underfoot.

That's not what happened.

What happened is stranger. Things I can do now that I couldn't do three months ago — not because I learned new skills, but because the tool removed the barriers that made certain work impossible for one person.

I can hold an entire project in a conversation. Not in my head — in dialogue. Strategic thinking that used to need a team and a whiteboard and three meetings — I can do in an afternoon. Not because I'm faster. Because the overhead is gone.

I can build things. Actual working things — tools, prototypes, structured analyses — that used to require skills I don't have and budgets I couldn't justify. Not toy versions. Real ones. The gap between "I can see what this needs" and "I can make it exist" has collapsed.

I can see my own expertise from the outside. Not just use it — examine it. Working with AI means making your judgment legible: why this approach and not that one, what pattern are you recognizing, where does the intuition come from. It's like seeing the skeleton inside the body. The structure was always there. You just never needed to look at it before.

None of this is what I expected. I expected to get better at something I already did. What actually happened is that the category of what I do changed.

But here's what's disorienting: the old knowledge didn't become irrelevant. It became... something else.

Years of judgment, pattern recognition, intuition built from watching things go wrong in ways that never make it into case studies — all of that is still there. More useful than ever, in some ways. AI is spectacular at generating. It's terrible at knowing when to stop. That's where judgment lives.

And yet.

The same expertise that makes me valuable is also the thing that slows me down. The instinct to double-check everything because that's what thoroughness means. The reflex to build consensus before acting because that's how organizations work. The pattern where "I'll research it first" is really "I'll delay until I'm certain" — and certainty never comes.

What do you call knowledge that's simultaneously your biggest asset and your biggest obstacle?

I don't have a word for it. But I know what it feels like. It feels like driving with one foot on the gas and one on the brake. And the car is new, and the road is unfamiliar, and your muscle memory keeps reaching for a gear stick that isn't there.

The instinct is to learn your way out of this. Read more. Take the course. Master the framework. Stack new skills on top of old ones until the stack is tall enough to see over the uncertainty.

That instinct is wrong.

Not because learning is bad. But because the disruption we're in isn't specific enough to learn for. It's not "AI will replace accountants" or "AI will change marketing." It touches everything differently, at different speeds, and the shape it takes tomorrow isn't the shape it has today.

You can't learn your way out of ambient disruption. The curriculum doesn't exist yet. By the time it does, the disruption has moved.

What you can do — what I'm trying to do — is shift the question.

From "What should I learn?" to "How should I see?"

From accumulating skills to developing perception. Not eyes-on-the-road driving — more like the peripheral vision that catches the thing you weren't looking for. The ability to notice what's changing before you can name it.

This is where unlearning stops being a concept and becomes a practice.

Digging the wrong hole was the beginning. Choosing a position — Ai over AI, fluency over nativity — was the next step. But a position is just a place to stand.

The practice is what comes after. And the practice looks like this:

Working at one level technically — doing what I can do right now, with the skills I have — while thinking at a level I haven't reached yet. Not pretending to be there. Just... looking in that direction. Letting the tool extend my reach while my judgment decides where to reach.

Sitting with the discomfort of not knowing. Not filling the gap with a framework or a certification or a twelve-step plan. Just noticing: this is uncomfortable, and the discomfort is information.

Watching for the things that are neither old nor new. The calculator metaphor from before breaks down here. This isn't "old tool → new tool." It's more like discovering that what you thought was a calculator — your pattern recognition, your judgment — was actually something much larger. You couldn't see its shape because the old way of working only used a fraction of it. The spreadsheet didn't replace the calculator. It revealed that what you were holding all along was judgment, experience, and a way of seeing that no tool can generate — only surface.

I started this journey looking at AI. What it could do. How to use it. Where it was going.

Then I started seeing Ai. What it changed in me. How I think differently. What it surfaced that was always there.

Now I'm somewhere I didn't plan to be. Not looking at AI or even at Ai, but looking at the world through it. And the world looks different.

Not better or worse. Not simpler or more complex. Just — different. In a way I'm still learning to describe.

That's not a conclusion. It's not even a position. It's just where I am right now — practicing, unlearning, watching what emerges when you stop holding on.

If any of this sounds familiar — the ground shifting, the old skills that help and hinder in the same breath, the feeling that you can't prepare for something you can't name — then you already know what I'm talking about. You don't need a curriculum. You need to notice what you're already seeing.

Catch you next time.

Co-created with AI. The judgment is mine.

I don't want to be AI-native.

I want a pen in my hand to think. I still print my docs to draft them — write on the paper, touch it, feel it exist outside a screen. I could do it digitally. I'm typing this on my laptop right now. But first, I wrote the idea on a piece of paper. Then another. When the idea finally clicked, I typed it up.

That process isn't inefficient. It's how I think.

And I don't plan to give it up.

Here's the thing nobody says out loud: AI-native is not for everyone. And that's not a limitation — it's a position.

AI-native means AI is your first language. You think in prompts, iterate in chat windows, build in AI-first tools. Some people are there already. Good for them. Seriously.

But being AI-native isn't a destination everyone should be racing toward. It's one stance among several. And I've chosen a different one.

I arrived at AI carrying something: years of building judgment before any of this existed. Mass media, the first computers, the internet revolution, mobile. Layer after layer of technology that promised to change everything — and did, but never in the way the hype predicted.

I don't want to pretend those layers didn't happen. I want to use them.

I want to be AI-fluent.

AI as a second language. Not the first. Never the first.

This isn't an age thing. It's not "if you're over 50, settle for fluency." It's a deliberate choice — available to anyone who recognizes that the most valuable thing they bring isn't speed with the new tool. It's what they knew before the tool arrived.

Fluency means I can work with AI, think alongside it, use it to amplify what I already know. But my thinking starts on paper. My judgment was built before AI could generate an opinion. My pattern recognition comes from years of doing things the slow way — the way that builds real understanding.

That's not a weakness in the AI era. That's an edge.

There's a way to see this that makes it clearer.

AI — capital A, capital I — is the spectacle. The revolution everyone's announcing. The capabilities, the benchmarks, the "this changes everything" posts. AI is what it can do. The loud version. The hype.

Ai — small i — is what it actually changes in you. How you think differently. What it reveals about your own knowledge. The quiet version. The shift nobody writes headlines about.

AI-native lives in AI. Immersed in the spectacle. Tracking every model release, every capability leap, every new tool. That's useful. It's also exhausting and — for me at least — a trap.

AI-fluent practices Ai. Not chasing what the tool can do, but noticing what it changes in how you work. Different question. Different pace. Different outcome.

The fluency I'm after isn't about keeping up. It's about going deep enough that the tool starts surfacing things you didn't know you knew.

But becoming fluent requires something uncomfortable.

Unlearning.

Not learning new skills. Unlearning old patterns. The ways of working that got me here are exactly what's holding me back.

It's like trying to use a spreadsheet while your brain insists on reaching for a calculator. The calculator worked fine. It got you results. But the spreadsheet is a different beast — and you can't use it well while your hands still reach for the old tool.

AI is the same. It doesn't respond to effort the way traditional tools do. It doesn't reward grinding. It rewards clarity. And clarity comes from knowing yourself well enough to recognize which of your old patterns need to be rewired.

This isn't about raw speed or novel problem-solving. It's a rewiring exercise. Taking accumulated knowledge and pattern recognition — the stuff that makes you valuable — and reconnecting it to work with this new tool instead of against it.

That takes energy. It takes patience. And it takes the honesty to admit that what made you successful might be the exact thing slowing you down now.

I'm not AI-native. I don't want to be.

I want to be fluent. To carry everything I've learned into this new era, shed the patterns that don't serve it, and use AI to amplify the rest.

And the unlearning part — the rewiring — that's where it gets interesting. That's where the real practice begins.

But before the practice — a breath. You don't have to race toward AI-native. You don't have to keep up with people who started from a different place. There is a position to choose here. Not a default. A deliberate one. And you can only see it if you stop running long enough to look.

Catch you next time.

Co-created with AI. The judgment is mine.

Four months ago, I didn't use AI. I'm over 50 — I have my way of working, my tools, my process. AI was for other people.

Then I started. And I did what everybody does.

First reaction: fear. Am I being replaced? Decades of building judgment and suddenly there's a tool that can do pieces of my work faster than I ever could.

Second reaction: compete. Learning to prompt like a 25-year-old. Watching tutorials. Collecting techniques like trading cards. Racing to keep up, because the noise was loud and confident, and it felt like falling behind to ignore it.

It felt productive. I was keeping up.

I wasn't.

Third reaction — the one that took me two months to find: What if AI doesn't replace what I know, but removes everything around it?

What changed wasn't a better tool or a better prompt. It was a shift in what I was paying attention to.

I stopped asking what can AI do? and started noticing what does it change in how I think?

That sounds subtle. It isn't.

When I was chasing tools, I was looking for speed. Make this faster. Automate that. Get to the answer in fewer steps. And yes, AI does that — maybe thirty times faster for certain tasks. Fine. Useful. But not the point.

The real shift was different. I started articulating things I'd known for years but never needed to make explicit. Judgment calls. Intuitions about why a project is going sideways before the data confirms it. The weird connections between unrelated domains that nobody asks you to explain because they just watch you do it.

AI forced those things out of the background. Not because AI understands them — it doesn't. But because working with AI requires you to say what you mean with a precision that human collaboration never demanded. And when you do that — when you take implicit knowledge and make it explicit — something compounds. Not faster. Different.

Not a better version of the old work. A kind of work that didn't exist before.

But here's the trap. Two traps, actually.

The delegation trap. It's easy to let AI think for you. You ask a question, get a beautiful answer, and move on. You feel productive. But you didn't think. You outsourced the one thing that makes you valuable. Do that for six months and you've lost the muscle.

The mirror trap. AI reflects you back. Ask it to validate your idea, it will. Ask it to agree, it will. It's the most sophisticated yes-man ever built. If you're not careful, you'll mistake its agreement for truth. You'll build an echo chamber of one.

Both traps feel like progress. Both are erosion.

There's something else I'm noticing, and nobody's talking about it.

The overhead of working together — the back-and-forth, the informal check-ins, the messy coordination — is dissolving. AI holds the context, drafts the summary, flags the decision. It feels like efficiency. But some of that overhead was how we actually learned. The hallway conversation where someone says "this doesn't feel right." The redundant check-in that surfaces a weak signal before the data confirms it. The argument that nobody wanted to have but that built shared understanding.

AI optimizes the output and quietly displaces the process underneath. Nobody's announcing this. It's just happening, one AI conversation at a time.

But something else is compounding too. Every conversation with AI builds on the last one. Not AI's memory — yours. Your ability to ask sharper questions. To spot when the answer is generic. To know when to push back and when to follow the thread. It compounds slowly. Be patient with yourself.

I don't have this figured out. I'm four months in and some of that time was wasted — or felt wasted, though I'm not sure anymore. Maybe the wrong hole was necessary. Maybe you can't find the right questions without exhausting the wrong ones first.

What I know is this: I was looking for AI. Tools, capabilities, the next breakthrough. What I found was something smaller and more useful. A different way of working with what I already knew.

That's not a conclusion. It's a beginning.

And if you're reading this from somewhere inside your own version of this — chasing, collecting, trying to keep up — you're probably in your own wrong hole right now. That's fine. The question isn't whether you're in one. It's how long you stay after the ground stops giving.

Catch you next time.
