Spec-Driven Development: Writing Specs Is the Highest-ROI Engineering Move in the AI Era — Learn AI Slowly 177
Your Biggest Mistake Isn’t Not Buying Tools, It’s Not Writing CLAUDE.mdA regional carrier’s CIO complained to me: “We’ve bought AI tools, deployed models, and even trained our people, but by the end of the first half of 2026, our delivery cycle hasn’t changed much. The head of the core systems team was even more blunt: ‘The AI-generated code works, but we have to rewrite it every time – it doesn’t understand our bank’s rules, it doesn’t understand the regulatory requirements, and it doesn’t k...
Compliance Path: App Builders & AI IDEs — The Door to Development Is Open, but the 5 Gates to User Data Still Stand. Software Engineering in the AI Era — Learn AI Slowly 176
The Barrier to Building Apps Has Disappeared, But Not the Barrier to Accessing User DataRecently, a mid-platform manager from an e-commerce company has been asking me the same question: why can the business side build three internal tools using AI in just one week, while the IT development schedule is still pending for next quarter? What’s the holdup? Our answer is simple: the barrier to development has disappeared, but the barrier to accessing user data remains. This statement reflects two c...
[Code Review] Code Review in the AI Era — Who Reviews the Code After AI Writes It? | Software Engineering Transformation in the AI Age — Learn AI Slowly #174
Code Review in the Age of AI — Who Reviews When the Code Is Written by AI?In the previous piece (AI173), I named “verification” as the third new bottleneck once code becomes nearly free, and closed with a line saying “I’ll cover it in its own section.” This piece delivers on that promise. Here is the conclusion upfront: looking back from mid-2026, the variable that AI coding tools actually delivers is neither license counts, nor seat counts, nor model benchmarks — it is review bandwidth. AI17...
The AI tool war is over—but whether winners actually benefit is another story—Software engineering in the AI era · Learn AI Slowly 175
The AI Tool Wars Are Over, But Will the Winners Be Adopted?Learn AI Slowly #175Let’s cut to the chase. By mid-2026, it’s clear that the top spot in the AI tool market isn’t being contested by four tools, but rather, it’s been taken over by Claude Code and Codex. To be precise, they’ve dominated the high-autonomy segment, which truly compresses the end-to-end delivery cycle. GitHub Copilot still leads with a 29% adoption rate in the workplace, but that’s largely due to enterprise purchasing in...
[Bottleneck Shift] When Code Is Nearly Free, Where Has the Bottleneck of Software Engineering Gone? The Transformation of Software Engineering in the AI Era — Learn AI Slowly #173
When Code Is Nearly Free, the Bottleneck Shifts to Requirements, Integration, Validation, and AlignmentWhen code production becomes nearly free, the bottleneck in software delivery shifts away from “writing code” to: defining the right problem, assembling fragments into a working whole, verifying it’s actually correct, and aligning the organization. This is a replay of the Theory of Constraints in software engineering. Manufacturing walked this path 40 years ago: whenever one step became chea...
Team Topologies — Organizational Design for the Post-Agile Era (Learn AI Slowly 172)
Before You Adopt AI, Reorganize Your Teams Around Value StreamsBefore you bring AI into your company, there is one move that pays off more than any tool or model you might pick: reorganize your technical teams around value streams. I’ve watched too many enterprises buy the tools, deploy the models, train the people — and delivery still drags, while the team comes out more exhausted than before. The root cause is almost never weak AI. It’s that the teams are sliced along technical layers — fro...
[Your Organizational Structure Has Already Decided Your Software’s Fate] Conway’s Law — The Management Law Underestimated for 56 Years AI Era Software Engineering Transformation — Learn AI Slowly #171
Before We Begin Your software architecture isn’t “designed” by your engineering team—it “grows” from your organizational structure. This 1968-era law is being repeatedly validated in the AI age. Harvard Business School’s empirical research proves: organizational distance predicts software defect rates more accurately than code complexity. What you call “technical debt” is often, at its core, “organizational debt.” Amazon’s microservices empire, Spotify’s squad model, Apple’s Siri deadlock...
The $100 Billion Lesson: Why Corporate AI Assistants Forget Critical Contexts, Allowing Competitors to Boost Performance by 90% — Slowly Learn AI 169
Introduction Most AI failures aren’t due to a lack of intelligence in the models, but rather the absence of context engineering—information wasn’t properly “written, selected, compressed, or isolated.” Ignoring context equates to real financial losses: from the Bard launch debacle to “260 chicken nuggets,” companies are paying the price for memory deficiencies. Blindly extending context only amplifies noise and attack surfaces; small and precise context management is the key to performance an...

$20 Subscription Plans Are Killing AI Companies: The Illusion of Token Price Drops and the Real Cost of Your Greed
Introduction The notion of reducing model costs is a fallacy: it’s the outdated models, which nobody uses, that are the ones getting cheaper. Users will always pay for the strongest “new flagship.” The real cost pit isn’t the price per token; it’s the evolution of AI capabilities: the more complex the task, the more resources consumed, ensuring that a fixed monthly subscription model will eventually be “crushed.” The AI subscription model is a “prisoner’s dilemma”: choosing pay-per-use means ...
