Who Moved My Cheese?

A Survival Guide for Software Developers in the AI Era

The book Who Moved My Cheese? looks simple—almost childish.
But its lesson is brutally relevant for software developers living through the AI era.

AI didn’t just improve our tools.
It moved the cheese.


The Cheese Was Never the Code

For years, many developers believed their value came from:

  • Writing code faster than others
  • Memorizing frameworks
  • Knowing syntax deeply
  • Producing large amounts of code

That was the cheese.

Then AI arrived.

Suddenly:

  • Boilerplate is free
  • CRUD apps take minutes
  • Tests, docs, and refactors are automated
  • Junior-level tasks evaporate

The cheese didn’t disappear.
It moved.


The Maze: Modern Software Development

Today’s maze includes:

  • AI coding assistants
  • Agentic workflows
  • Auto-generated infrastructure
  • Low-code and no-code platforms
  • Clients asking: “Why is this still expensive?”
  • Faster expectations, tighter budgets

Standing still in this maze is not neutral.
It’s moving backward.


Developer Archetypes in the AI Era

🧱 Hem – The AI Resister

  • Says AI code is “bad quality”
  • Avoids AI tools
  • Defends old workflows
  • Complains about the industry

Result:
Still in the maze. No cheese.


😰 Haw – The Reluctant Adaptor

  • Feels threatened by AI
  • Tries AI cautiously
  • Learns to review and guide output
  • Gradually gains confidence

Result:
Finds new cheese.


👃 Sniff – The Early Observer

  • Notices AI trends early
  • Watches model progress
  • Shifts focus from syntax to systems
  • Prepares before disruption hits

Result:
Moves before panic.


🏃 Scurry – The Fast Executor

  • Uses AI daily
  • Automates boring work
  • Ships faster
  • Experiments aggressively

Result:
More output with the same time—or less.


When the Cheese Moved (The AI Moment)

For developers, the cheese moved when:

  • Copilot wrote half the code
  • AI generated full applications
  • Clients expected faster delivery
  • “Effort” stopped being impressive

At that moment, coding skill alone stopped being enough.


The New Cheese for Developers

The new cheese is not:

  • Writing everything by hand
  • Mastering one framework forever
  • Measuring value by lines of code

The new cheese is:

  • Problem framing
  • System architecture
  • Integration across systems
  • Reviewing and correcting AI output
  • Reliability, security, scalability
  • Business and domain understanding
  • Owning outcomes, not tasks

AI didn’t remove developers’ value.
It moved it up the stack.


What Successful Developers Do Differently Now

They:

  • Use AI every day
  • Treat AI like a junior engineer
  • Focus on what to build, not how to type it
  • Spend more time thinking, less time typing
  • Measure success by impact, not effort

They don’t protect old cheese.
They go find new cheese.


A Question Worth Asking

What would you do if you weren’t afraid of AI?

Most honest answers sound like:

  • Build faster
  • Learn new domains
  • Take bigger bets
  • Focus on leverage
  • Charge for results, not hours

That’s where the cheese is.


Final Thought

AI won’t replace software developers.

But it will replace developers who refuse to move.

The maze still has cheese.
Just not where it used to be.
