Two boys

Twenty-five years ago, a boy rode his bicycle to a friend's house every morning. Two high school students with one aging computer, a book on C programming, and a desire to build a game. The only game they knew was Tetris.

They debugged line by line. They rewrote logic repeatedly. Every falling block was manually implemented. When the score counter finally started moving and the game actually worked, they played the whole day just to compete for high scores.

That boy was me. Because of that game, I chose Computer Science. I have spent the last 26 years writing code. That summer defined my craft.

Recently, I witnessed a different version of that moment. My twelve-year-old son broke his arm in a skiing race at Schweitzer and was stuck at home. Using AI coding agents, he built a small reaction-training game in about an hour. It worked. It kept score. It refined itself as he prompted it.

He did not construct every detail manually. He specified intent. The system implemented. Watching him, standing in the center of the AI vortex of 2026, I fell into a deep silence.

I had to ask myself: what is actually happening here? Is AI just a better tool?

No. The difference was not simply speed. The difference was structural.

The first externalization

Human civilization has experienced one transformation of similar magnitude. When literacy became widespread, thought was externalized.

Before writing, knowledge depended on memory and physical presence. Ideas were fragile and local. With writing and printing, ideas could be recorded, duplicated, transmitted, and accumulated across generations.

Thoughts became scalable. Civilization accelerated because cognition was no longer limited by biological memory. We could think across time.

The second externalization

What is happening now may be more profound. AI systems generate code. Agents execute workflows. Robotics perform physical operations. We are externalizing not just intelligence — but action.

Some might ask: didn't the Industrial Revolution already do this? No. The Industrial Revolution externalized muscles. It amplified force. But the machine still required a human to operate it.

This wave is different. It externalizes the union of intelligence and action. It liberates humans from the necessity of labor — both mental and physical.

This is action externalization. And action, unlike thought, changes the state of the world directly. Civilization scaled when thought became external. It restructures when action does. Action becomes infrastructure.

The migration of scarcity

When literacy spread, the ability to write ceased to be rare. The differentiator became depth of thinking and structural coherence.

When action becomes externalized, scarcity moves again. If execution is abundant — if building, coding, operating, and even physical tasks can be delegated — then execution is no longer the constraint.

The constraint shifts upstream. The scarce capabilities become:

• Choosing direction
• Defining problems precisely
• Designing systems rather than performing tasks
• Taking responsibility for outcomes at scale

Why this gets harder, not easier

Automation reduces the cost of doing. It does not reduce the cost of deciding. In fact, it increases it. Because when action scales, consequences scale.

Externalizing thought expanded civilization safely because ideas required interpretation before becoming action. Externalizing action removes that buffer. The gap between intention and impact narrows.

Said differently: the leverage of every decision goes up. A good decision moves more of the world than ever before; so does a bad one. The work of deciding well — building the judgment, the context, the discipline that produces good decisions under leverage — becomes the scarcest civilizational capability.

The new craftsmanship

That summer building Tetris, I learned that value comes from the struggle of execution.

My kids will learn something different. In a world of action externalization, the barrier to creation is close to zero. But the barrier to meaning is higher than ever. When 'doing' becomes free, 'choosing' becomes the ultimate skill.

We are transitioning from a generation of Builders to a generation of Architects of Intent. The defining question of the next decade will not be: what can we build?

It will be: what is worth building?

Answering that question is a craft that can never be externalized. And should not.
