🧠 How tools reshape cognition
The questionWhat does using AI actually do to how we think, learn, and pay attention?
What it feels like to work with Mythos
Ethan Mollick · One Useful Thing
Ethan Mollick on the human role shifting from steering to commissioning as a frontier agentic model absorbs hundreds of judgment calls you never get a vote on, and the counterintuitive claim we may need more coders, not fewer. Lands directly on the unifying question.
"With Fable the spell has gotten powerful enough that I am no longer sure I am the wizard. I am closer to a patron. I describe what I want, I pay for it, and I judge the result. The conjuring happens somewhere I cannot watch, in hundreds of small choices I never get a vote on. The work has shifted from process to outcome. I no longer steer; I commission."
Design Is How It Tastes
Jem Gold · CodePen (Chris' Corner)
Jem Gold distinguishes "object-language" (tokens, radii) from "encounter-language" (the felt experience), arguing vibe becomes a programmable semantic layer above the design system as diffusion models parse sensory prompts directly. Touches cognition, translation, and planning artifacts at once.
"If our design specs only tell models what the interface is made of, they have already forgotten what the interface is for."
🔍 Translation vs. understanding
The questionIs AI genuinely understanding, or just translating context into plausible output, and where does real human comprehension still earn its keep?
How I Ship Real Software with Claude Code (Without Being a Developer)
Focused Chaos
A non-developer's retrospective on shipping a real product: pass/fail rubrics that define "done" before work starts, lean CLAUDE.md files where every rule is "a scar," and the argument that understanding (not the config) is the asset. Also hits agentic-dev patterns and planning artifacts.
"Your instruction file shouldn't read like best practices from a blog. It should read like a list of mistakes you've agreed not to repeat."
Father of the iPod and iPhone on building taste, judgment, and creativity in the AI era (Tony Fadell)
Lenny's Newsletter
A practitioner with deep skin in the game on taste and judgment when execution is cheap, framing cognitive surrender to AI as the biggest risk facing product builders. (Podcast, transcript behind video.)
"Why cognitive surrender to AI is the biggest risk facing product builders today."
Predicting AI Job Exposure
Benedict Evans · ben-evans.com
Benedict Evans argues scoring AI job exposure is impossible in principle: back-testing fails (a century of accounting automation grew accountants), the business can change under you even if the job doesn't, and you can't fully describe a job. Structural analysis that complicates the consensus.
"When you hire Bain, BCG or McKinsey, they will give you some slides, but that's not what you're paying for, just as when you buy software, you'll get some code, but that's not the product."
💰 Value concentration when creation costs collapse
The questionWhen building something gets cheap, where does the value (and the money) actually pool up?
Writing Code vs. Shipping Code: Productivity Effects Across Generations of AI Coding Tools
Murat Demirbas · muratbuffalo.blogspot.com
Murat Demirbas translates an MIT/Wharton paper into Amdahl's Law terms: task-level code gains (+228% to +741% lines) decay to +10–20% shipped releases because human review is a strong complement. The parallelizable fraction stays pinned at ~35%, capping speedup at ~1.53x. The deepest structural take on the AI-productivity gap.
"No matter how fast an autonomous bot can process a commit, the remaining 65% human sequential bottleneck acts as a hard stop... shipping software will remain an inherently human-throttled process."
Why Japanese Companies Do So Many Different Things
maximum-progress.com
Deep structural analysis (Milgrom-Roberts complementarity, Aoki's J-firm vs H-firm) of why organizational practices come in self-reinforcing bundles that resist piecemeal change: deep process knowledge as the scarce, hard-to-replicate moat. Cross-domain and timeless.
"Consider Sony, which by the 2000s manufactured every component of what would become the smartphone... But Sony didn't do it. It was Apple, an H-firm par excellence, that reimagined the entire product category from the top down."
The iPhone's Last Stand
Ben Thompson · Stratechery
Ben Thompson on the Apple vs. Microsoft strategic divergence (device-centric Siri AI vs. cloud-agent Project Solara), anchored by a non-consensus framing of where AI value concentrates.
"Enterprises are paying for their employees' time, so of course they are willing to pay for tools that make those employees more productive; consumers, on the other hand, are mostly looking to waste time, which is why attention-harvesting advertising is the only software business model that works at scale for consumer services."
8 Myths on Software Engineering and GenAI
newsletter.getdx.com
Research-backed: devs spend only 14% of time coding; typical org sees 7.8% throughput gain; one study found AI increased implementation time 18% for experienced OSS devs; 80% use AI tools but only 29% trust accuracy. The adoption-gap curiosity, with data.
"Measuring software productivity by lines of code is like measuring progress on an airplane by how much it weighs. (Bill Gates)"
The Pulse: a trend of trying to cut back on AI spend within eng departments?
The Pragmatic Engineer
The disconnect between impressive AI usage metrics and the inability to draw a line to shipped value, with real org data (Uber's CTO blew through the 2026 AI budget by March; DoorDash's justify-and-share token limits). Pairs with the DX and Amdahl pieces.
"How many projects 'on the cutting room floor' got moved above the line because of the productivity gains?... That link is not there yet."
Design is the work
Jake Albaugh · jake.fun
Jake Albaugh argues the bottleneck in the AI era is intentionality, not execution: design is deciding what should exist before building. "100 times zero is zero." Self-demonstrating, written by Claude from his Slack, but the argument was his.
"The most expensive thing you can do isn't build something badly. It's to execute well on the wrong idea."
Shopping with Claude
How I AI · Lenny's Newsletter
Nicole Ruiz documents a real build end-to-end: a Claude Project codifying an "invisible checklist" of purchasing criteria into reusable instructions, plus Cowork automating returns. A tool for an audience of one, with the structural insight that AI levels the field for heritage brands whose terrible websites lose to ad-heavy DTC.
"The worst websites often belong to the best manufacturers... AI allows you to bypass those clunky interfaces and get right to the quality products. As our guest Jason Levin once said, 'no UX is the best UX.'"
🪵 Thick engagement vs. thin optimization
The questionWhen is the slow, effortful, deep version of the work worth it, versus the fast and frictionless one?
Dopamine Fracking
igerman.cc
Coins a term for pumping disproportionate optimization into a layered activity to extract the purest dopamine hit while destroying what made it valuable. The strawberry metaphor (synthesizing the one aromatic compound, erasing 500 unique experiences) is a beautifully built cross-domain case against thin optimization.
"Tasty? Maybe. But it's not a strawberry anymore. It's just a chemical that kind of tastes like a strawberry. Soon enough, you forget what one actually tastes like."
The worst designer I've ever worked with was also the most productive
CodePen (Chris' Corner)
A war story borrowing the political tactic "flooding the zone" to describe how pure output volume collapses a team's ability to evaluate quality. Discernment as the scarce resource.
"The pile grew taller and the thinking grew thinner... When someone brags about how much they shipped, don't applaud. Ask what would've happened if they'd simply done nothing."
Cleaning up after AI rockstar developers
Jesse Skinner · codingwithjesse.com
Jesse Skinner extends the "rockstar developer" metaphor to AI agents: every new chat risks adding a rockstar, producing a codebase "written by hundreds of different rockstars." Maintainability and craftsmanship as the things that can't be outsourced.
"Craftsmanship will always be in our hands, it's one thing we can never outsource to a machine."
Find a Way
usefulfictions.substack.com
Cate Hall personifies "Melvin," the part of us that does the normal-shaped action to avoid blame rather than solve the problem; mediocre effort is often rational because of covert conflicting goals.
"Discouragement is just an emotional state, not a map of the boundaries of the possible."
🚀 Small teams, disproportionate output
The questionHow do tiny teams punch so far above their weight?
How Claude Code Works in Large Codebases: Best Practices and Where to Start
claude.com
Practitioner guide on Claude Code at scale: agentic search vs RAG staleness, "the harness matters as much as the model," self-improving hooks, and the emerging "agent manager" role. Squarely in the agentic-dev-patterns interest.
"One challenge with large codebases is that good setups can stay tribal... Without that work, knowledge will stay tribal and adoption will plateau."
Doing nothing at work
Sean Goedecke · seangoedecke.com
Sean Goedecke argues engineers should run at ~80% utilization because performance is dominated by time-dependent outlier events you can only seize if you're not already busy. The invisible leverage of staying loose.
"Nothing is a space things can happen in... There are no points for effort in software development. What matters is solving the right problem at the right time."
🤝 Intentional hospitality as a practice
The questionWhat if you designed care into how you treat people, deliberately, as a real competitive (and moral) advantage?
Trust Factory
Kent Beck · Tidy First?
Kent Beck reframes XP practices as a "trust factory" and finds a self-reinforcing meta-pattern: every practice that creates trust also encourages trustworthiness. Applies it to AI "single player" dev, where the genie cares about prompts, not purposes.
"We're accumulating code faster than we are accumulating trust... software is bipedal, code & trust go together. One without the other just hops along awkwardly."
If You Are Asking for Human Attention, Demonstrate Human Effort
tombedor.dev
A crisp etiquette principle for the AI era: clearly label AI output and add your own effort before forwarding it to a human. Captures a real emerging dynamic around attention as a scarce, shared resource.
"I didn't read this, so it might not be entirely accurate... My thought was, if reading this wasn't worth your time, why is it worth mine?"
🗺️ Planning artifacts shape the work
The questionHow do the documents you write (specs, decision records, the agent's workspace) steer what actually gets built?
I design with Claude more than Figma now
blog.janestreet.com
A Jane Street designer documents shifting from Figma mockups to building real prototypes in the production codebase ("prototypes are living proposal docs, the code is disposable"). An LLM skeptic changing his mind, with an honest fear about being stuck in an iterative rather than creative mindset.
"There's also a fear I have that designing with Claude keeps me out of a fluid, creative mindset and stuck in an iterative one, constrained to the outcomes I think Claude can produce."
Making a New Plan
Cate Huston · cate.blog
Cate Huston on the underrated leadership skill of incorporating new information and making a new plan, and catching herself doing the very thing she judged others for. Hits the "writers who change their mind" signal directly.
"I realized I can just incorporate new information and make a better plan without it threatening my sense of self."
🧬 Transmission of capability
The questionHow does knowledge and skill actually move between people, and from people to AI?
How Does GenAI Change When and How Teammates Talk to Each Other?
rdel.substack.com
Research (30 devs observed, 131 surveyed) on how GenAI rewires team interaction: routine Q&A migrates to AI (51%; 62% find it easier without embarrassment) while human conversation concentrates on context and judgment. The casual teaching moments senior engineers created vanish with the routine questions.
"The tools are good at handling the routine questions. The conversations that build judgment and connection are yours to protect."
Walmart is training store-level employees to use AI
modernretail.co
How Walmart builds AI fluency across a 1.6M-person workforce via OpenAI/Google certificate programs, with real associate-built tools (a cake-decorating coaching app, a load-matching app to get drivers home), framed around keeping human judgment central while scaling capability per individual.
"For Walmart, the opportunity is not just to train people on AI; it is to build a learning model that can scale across a large workforce while still feeling relevant to each individual associate."
The Slide
Michael Lopp (Rands) · Rands in Repose
Rands on a specific coaching move: when direct feedback fails, slide up next to the discomfort with a personal story of your own struggle rather than lecturing. Sharp on why the hardest feedback contradicts the very skills that got someone the role.
"The Slide is you gently sliding up right next to that discomfort, that contradiction, and not accusing, not lecturing, just telling the story of that time you learned the thing."
5 Career Questions Your Old Playbook Can't Answer
Nikhyl Singhal · Lenny's Newsletter
Nikhyl Singhal works through five leadership questions, with the through-line that the playbook that got you to a leadership seat is the wrong one for the hardest questions from it. The "two superpowers collide, you get two shadows" diagnosis is genuinely sharp.
"Your superpower is managing people; the shadow is the blind spot that rides along with it... Their superpower is getting things done regardless of the obstacle; the shadow is that eventually the physics stop cooperating, and grit alone can't move the wall."
👀 On the radar
Lower-confidence picks worth a skim if the topic grabs you.
- Fable 5, Anthropic Alignment, AI Tiers Ben Thompson argues Anthropic's fusion of belief and business makes it "feel unbeatable" while the guardrails episode sets troubling precedents. Structural take on where AI moats form, but paywalled.
- Understanding Engineers' Needs (BICEPS framework, AI adoption & psychological safety), Lara Hogan Podcast on the BICEPS framework and making engineers feel safe about AI adoption. Squarely adjacent, but the written summary is paywalled, a listen rather than a verified read.
