Mental Models

Smalltalk Is the Only ‘Object-Oriented’ Language That Matters. The Rest Is Just Syntax.

Learning Smalltalk doesn’t teach you a language — it rewires how you think about code. Modern OOP languages are class-oriented, not object-oriented. They borrowed the syntax but abandoned the soul. This article explains why Smalltalk remains the purest embodiment of object-oriented programming and why revisiting it can reset your mental models.

The Password Is Dead. But Are You Ready for What Comes Next?

Passkeys replace passwords with invisible, device-bound proof. They feel like magic—until you lose your phone. The real challenge isn’t the cryptography; it’s unlearning a lifetime of password habits and learning to trust security you can’t see. A visual demo makes the trade-off clear: convenience for control, but only if you’re prepared.

Stop Using LLMs to Write Code Faster. Start Using Them to Change What You Build.

LLMs don’t accelerate development by writing code faster. They accelerate it by reshaping what developers believe is possible. The real gain comes from redefining what a modern app can be, not from automating known tasks. Pre-LLM mental models are the biggest risk—not being replaced by AI.

The Paper Trick That Breaks Your Brain (And Explains Wealth)

A standard sheet of paper, folded 42 times, would reach the moon. This isn’t a geometry trick—it’s the most dangerous blind spot in your thinking. We’re wired for linear growth, but the world runs on compounding. Wealth, technology, and power all follow the paper principle: they look flat, flat, flat, and then they’re gone. Here’s how to stop underestimating the exponential.

Stop Trying to “Think Outside the Box.” You Don’t Even Know You’re in One.

The greatest barrier to innovation isn’t a lack of resources or intelligence, but our inability to imagine realities outside our mental models. We tell people to “think outside the box,” but the hard truth is we don’t even know the box exists. AI might be our first real chance to see it.

Stop Naming Things. ‘Diff That Beetle’ Instead.

Isolation is the enemy of insight. Comparative biology proves that the most profound truths about life, markets, and products don’t come from studying things in a vacuum—they come from mapping the differences between them. If you want to understand the rules of the game, stop staring at a single data point and start looking for the meaningful differences.

The Quantum Physics Lie That’s Been Holding You Back

We’ve been taught that quantum mechanics is inherently mysterious—wave-particle duality, observer collapse, time-bending erasers. But a new framework reveals it’s all just accounting. Particles are always particles. Waves are projections. Observation is a forced audit. This isn’t just physics; it’s product management’s new operating system.

Git’s Terrible UX Is a Feature, Not a Bug. Here’s Why.

Git’s interface is notoriously terrible, but that’s not a flaw—it’s a feature. Drawing from the famous ‘Git Koans’ parable, this article reveals how Git’s opacity forces developers to internalize its data model through suffering, leading to true mastery. Stop fighting the tool and start embracing the Zen of version control.
