A Billion Builders

The future of building with AI

People who
can build

Shaped salaries, geography, education, power, culture for 30 years.

Everyone
else

"Technical" and "non-technical" became identity categories.

Personal story

I ran a software company for 15 years.
I still couldn't build the technology.

2022
ChatGPT arrives.
A party trick.
2023
Developers use it as a copilot.
Non-devs still on the outside.
2024
Karpathy coins "vibe coding."
Non-devs building real things.
2025
Full applications built by people
who've never seen a line of code.
2026
The wall is rubble.
We're only at the beginning.

The most valuable builder isn't the most technical.

It's the one who understands the problem the most.

So what changes?

The reshaping

The end of "not my job"

The dev backlog dissolves
Not because dev works faster — because most requests never get filed.
Power shifts
The person closest to the problem has the power to fix it. No permission, no budget, no engineering allocation.
The org chart flattens
Translation layers between problem-knowers and builders become unnecessary.
Management evolves
From allocating technical resources to developing taste and judgment about what's worth building.

What do I tell my nephew?

The old answer

  • Learn to code
  • Study STEM
  • Get technical skills
  • Find a technical co-founder

What becomes scarce

  • Understanding problems deeply
  • Taste and judgment
  • Domain expertise
  • Empathy
  • Knowing what not to build

The most addictive game loop ever designed

— attached to real outcomes.

The pull

A billion tokens a week.
This is what the pull feels like.

But there's more.

The honest reckoning

What gets disrupted

Developers

Outsourcing economies

The abundance problem

The first 95%
takes 5% of the effort.
The last 5%
is a completely different experience.
The prototype is a first date. The production app is a marriage.
4 AM. Lisbon.

Wife is asleep.

Agents hallucinating.

App broken in a way I can't diagnose.

I don't have
clean answers.

The direction is right — more people with the power to create is better than fewer. But I won't pretend the transition is painless.

Every time a barrier to creation has fallen — the printing press, the camera, the internet — people built things nobody predicted. The costs were also always real.

Can you build it?
Can you make it good?

Do your homework

What are you
going to build?

Build something tomorrow. Something small. The homework is yours.
