Chapter 7 — Electricity & Industrialization

What the electrification era teaches us about AI, productivity lags, workflow redesign, and why the true AI boom will arrive years after the hype.

If you were alive in the late 1800s, you would have witnessed one of the most breathtaking waves of innovation in human history. Within a single generation:

  • electric lights replaced gas lamps
  • electric motors replaced steam engines
  • factories buzzed with new machines
  • cities glowed with illuminated streets
  • homes adopted new appliances

It felt like magic — the same way AI feels like magic today.

But here’s the twist:

Despite the excitement, the world saw almost no economic or productivity growth for more than 30 years.

It wasn’t until the 1920s — decades after the invention of electricity — that industrial productivity finally exploded.

This long delay holds a critical lesson for the AI era.


Inventions → Productivity Lag → Explosion

The timeline of electrification is one of the clearest illustrations of how technological revolutions unfold.


1. Invention Phase (1870s–1890s) — “Look at this miracle!”

  • Edison invents the lightbulb.
  • Tesla and Westinghouse build alternating-current systems.
  • Cities wire streets and buildings.
  • Factories install early electric motors.

Society is mesmerized.
Electricity becomes a symbol of the future.


2. Productivity Lag (1890s–1920) — “Why hasn’t anything changed?”

Despite excitement, economists observed something strange:

Factories using electricity were no more productive than steam-powered factories.

How could that be?

Electricity was cleaner, safer, more reliable — yet output barely improved.


3. Productivity Explosion (1920s–1950s) — “Everything is different now.”

Only when companies redesigned their entire workflows did electricity unlock massive productivity:

  • assembly lines
  • specialized labor
  • conveyor belts
  • plant layouts optimized for flow
  • real-time machine coordination
  • automated equipment

Factory productivity increased 50–100% in a single decade.

Electrification didn’t transform the world when it arrived.
It transformed the world when workflows evolved around it.


Why the World Didn’t See Productivity Gains for Decades

To understand the delay, we must look at how steam-era factories were designed.

The Steam Factory Was Built Around a Single Power Source

In a steam-powered plant:

  • a giant central engine lived in the basement
  • belts and shafts ran across the ceiling
  • machines lined up in straight rows
  • layout was dictated by belt length, not efficiency

When companies “switched to electricity,” they made a fatal mistake:

They replaced the steam engine with an electric motor… but kept the entire workflow the same.

They still had:

  • tightly packed machines
  • layouts dictated by shaft length
  • centralized power
  • no flexibility
  • no experimentation
  • no process redesign

They adopted the technology, but kept the mindset.

This is why productivity didn’t improve.

They electrified their machines but didn’t electrify their thinking.


The “Workflow Problem”: Why Tech Must Be Paired With Process Redesign

Real productivity gains came when companies asked:

“If electricity lets us design the factory from scratch, how should we design it?”

This led to:

Decentralized power

Every machine got its own motor.

Flexible layouts

Machines could be placed anywhere.

Specialization

Tasks could be grouped by function, not belt alignment.

Flow-oriented manufacturing

Parts moved smoothly between stations.

Automation

Machines could coordinate without human force.

This redesign triggered the productivity explosion.

Electricity wasn’t valuable until workflows adapted — the same is true for AI.


AI Is in the Same “Early Buildout” Phase Today

Modern AI is mesmerizing.
It automates tasks, assists workers, accelerates analysis.

Yet global productivity numbers remain modest.

Economists ask:

  • “Where is the AI revolution in the data?”
  • “Why haven’t output numbers improved?”
  • “If AI is so powerful, why isn’t GDP growing faster?”

The answer mirrors the electricity era:

AI has been added to old workflows, but workflows haven’t been redesigned.

Examples:

  • Lawyers use AI for drafts — but legal processes remain unchanged.
  • Developers use copilots — but SDLC workflows remain unchanged.
  • Call centers use summaries — but support processes remain unchanged.
  • Companies use AI chatbots — but customer operations remain unchanged.

AI is being “plugged into” 20th-century processes.

What’s missing is the 21st-century workflow.


When Will the AI Productivity Boom Begin?

The shift will begin when companies stop asking:

“Where can we insert AI?”

…and start asking:

“How should this entire workflow be redesigned now that AI exists?”

The electricity analogy predicts:

The real AI productivity explosion will not happen in 2025 —
it will happen in the early 2030s.

Right now:

  • we are wiring infrastructure
  • building data centers
  • building tools
  • experimenting
  • integrating
  • learning
  • failing
  • iterating

Just like electricity in 1900.

We are in the buildout phase.
The redesign phase comes next — and that’s when AI becomes transformative.


The Lesson for AI: Tools Alone Don’t Change the World — Workflow Redesign Does

The companies that win the AI decade will be those who:

  • understand workflows deeply
  • identify bottlenecks
  • break processes apart
  • redesign roles around human + AI collaboration
  • reorganize teams based on new capabilities
  • treat AI as a workflow engine, not a feature
  • reimagine entire systems, not just functions

This is the difference between:

  • a company that uses AI, and
  • a company transformed by AI.

In the next chapter, we move from electricity to the Industrial Revolution, where workforce shifts reveal what AI will do to jobs, skills, and economic classes.
