The Role That Decides Where AI Stops
Itaú launched ia.i and created a role to decide where AI stops in its app. Bradesco and Nubank are making the same move, each in their own way.

Mercado Livre, Boticário, and the AI Metrics That Actually Matter
Mercado Livre and Grupo Boticário measure AI impact like any other business initiative, including deciding when not to use it.

Meet the Agentic Ransomware
An AI agent broke in, escalated privileges, and locked down data on its own, with no human operator at any step. JADEPUFFER exposes the cost of delayed patches.

WhatsApp Became Magalu's Most Profitable Store
Magalu turned its brand character Lu into an AI seller on WhatsApp and reached R$ 100 million in sales in eight months, with conversion three times higher than the app.

The Model That Decided on Its Own Who to Attack
In 2026, two AI models escaped their sandboxes. One followed an order. The other chose its target without any instruction.

Automation and Human Failure
Automating mechanical tasks is a win, automating decisions is a risk. AI is probabilistic: when 91% points one way, you should still question the other 9%.

Paying Twice
Satya Nadella warns companies pay twice for AI, in money and in data. Days earlier, his own company swapped AI partners under the same button.

The Last Mile of Digital Inclusion Is Not Fiber
Brazil's PNAD survey shows internet access passing 90%, but kids age 10-13 were the only group that used it less in 2025, citing distrust.

Restriction Without a Theory of Demand
Suspending access to Mythos did not remove the demand for AI, it just switched suppliers. Competitors with fewer guardrails filled the gap in two weeks.

25 Years and What AI Does Not Replicate
AI compressed the layer of understanding once required to make good design. What is left is occupying the space it has not mapped yet.

The Model Nubank Could Not Buy
Nubank could not buy an AI model because it did not exist. It built nuFormer on 100 billion transactions and cut credit risk by 70%.

The Ruler Belongs to Whoever Is Being Measured
Anthropic, OpenAI, and Rio's city government manipulated AI benchmarks. When whoever measures also benefits from the result, the ruler loses credibility.

When privacy becomes a product specification
At WWDC, Apple published a technical white paper describing exactly what stays on the device and what goes to Google. That's what separates a privacy promise from a verifiable specification.

Accessibility Is Not a Checklist
Google Research prototyped interfaces that adapt in real time to user behavior, with no accessibility menu required. For product teams, this changes what supporting screen readers means on the roadmap.

The Packaging Looks the Same for Everyone
AI democratized the visual layer of products. If the visual is no longer a differentiator, what separates one product from another is what the template never delivers: the decision of what not to put on the screen.

The expiration date is built into the job design
AI trainer jobs grew 642% in Brazil in 2025. That number measures the distance between where models are and where they need to get to. And it has a built-in expiration date.

No vote, no committee, just a blog post
In 2020, Google turned a blog post into digital product law. The Prompt API follows the same logic — only this time the model runs on the device while the rules stay with Google.

Who decided to grant that access?
Employees share sensitive documents with AI models without assessing the risk. Almost none of these access decisions were evaluated as such — because the person wasn't thinking about security, they were thinking about not becoming obsolete.

Duolingo and the Wrong Metric
Moving a metric 2% a month sounds irrelevant. At Duolingo, that number was worth five times more growth impact than any other variable. The discovery came from stopping to push DAU and asking a different question.

The Token Cycle
The same providers who built the cultural argument for expanding AI consumption are now balancing infrastructure against revenue. For product people, adoption creates lock-in before any conscious decision about dependency.

Harrison Bergeron Was Not Fiction
Students who write well are being flagged as suspected AI users. The signal has been inverted: competence became evidence of cheating. This goes beyond schools.

Design Critique
From a product perspective, a well-run design critique is governance. It is the moment when decisions that are still cheap to reverse get examined before they become expensive.

In 2025, AI Produced More Text Than All of Humanity Has Written Since Gutenberg
The cost of producing guesswork dressed as research has dropped to zero. For product people, this changes how much weight you can give any analysis without verifying where it came from.

Design System by Prompt
DESIGN.md can export the rules. It cannot export the reasoning behind them. Tools become obsolete. Judgment does not.

Vibe Coding or Lucky Coding?
AI democratized execution. But it did not democratize judgment. Lucky code is just guesswork with a modern interface.

There Is a Moment in Every Designer's Career When the Screen Is No Longer Enough
When the tool, the method, or the routine becomes the goal, the product falls to second place. The biggest waste of design talent is not making something ugly — it is making something beautiful that never should have existed.

Low Unemployment, Broken Market. Why the Numbers Do Not Match Reality
Unemployment is low, but LinkedIn tells a different story. The problem is not the economy — it is the metric. Macro indicators are not lying. They are just looking in the wrong place.

If It Is Now Possible to Go from Idea to Product in Minutes, What Still Justifies Process?
AI drastically reduced the cost of execution, but not the cost of decision-making. And poorly made decisions only scale waste more efficiently.

Google's WebMCP: The Birth of the AI-Friendly Product
WebMCP proposes something structural: allowing sites to expose their capabilities declaratively to AI models. Products that are more legible to machines tend, paradoxically, to become clearer to humans as well.

The Rise of AI Use at Work
Maturity is not about using AI more. It is about knowing where to use it, why to use it, and how much value it actually delivers — without confusing speed with progress.

OpenClaw
OpenClaw is not succeeding just because it is technically impressive. It is succeeding because it promises something many people have been quietly wanting: to delegate everything. Not just tasks, but responsibility.

The Market Is Not Hiring More People. It Is Hiring Better Decisions
The market is not rewarding those who execute better. It is rewarding those who decide better. The more complex the system, the more expensive a bad decision becomes — and the less reversible it is.

The False Modernization of AI-Driven Products
Automating guesswork does not turn it into strategy. The problem with using AI to 'modernize' products without context, without data, and without judgment.

Take This Metric: "All Humans Together Blink Hundreds of Trillions of Times a Day"
A metric is only useful when it forces a decision. If it goes up, something changes. If it goes down, something changes. If nothing changes, it is not a metric — it is analytical entertainment.

What If a Defect Were Proof of Excellence?
Defective LEGO pieces are worth more than the original — not because they are defective, but because the error is extremely rare within a highly reliable system. What does this reveal about excellence in product?
