## The Genesis of EROOM: Reversing Moore’s Law

The EROOM project was born from an idea by Tristan Nitot, based on a simple observation:

if digital technology has revolutionized the world over the past fifty years, it’s largely thanks to Moore’s Law, which states that computing power doubles every two years.

But that law… is now dead.

### A Blessing in Disguise

This isn’t a catastrophe — quite the opposite.

Moore’s Law has always had an inverted twin: Wirth’s Law, which observes that software slows down as fast as hardware speeds up.

In other words, the more powerful the machines, the more we waste that power through poorly optimized software.

Why?

Because there’s no incentive to write efficient code — developers’ time is usually spent adding features instead.

The result: heavier, more complex software… and often, less efficient.

### A Striking Comparison

In 1969, Apollo 11 landed on the Moon with a computer running at 1 MHz, with 4 KB of RAM and 36 KB of ROM, weighing 32 kg in total.

By 2017, a smartphone carried 3 million KB of RAM and an 8-core 2.4 GHz processor — roughly 70,000 times the computing power of the Apollo 11 module.

And what do we do with all that power? We watch 5G videos… in the elevator.

### Changing the Paradigm

Since 2021, the end of Moore’s Law has become an opportunity — to put software optimization back at the heart of our priorities.

The potential gains are staggering: some programs run 60 times faster after a simple optimization, and a developer named Matt Parker even managed to multiply his code’s performance by 408 million.

That’s when Tristan had an idea:

> “If we optimized software by a factor of two every two years, we’d free up half of the computing power for new uses.”

In other words: if we improve software instead of replacing hardware, we double the available power without changing anything.

That’s EROOM’s Law — Moore, reversed.

### Why It’s Great News

Adopting the EROOM methodology means:

  • Cutting the environmental footprint of digital technology by a factor of 4 to 5.

  • Continuing to innovate without relying on constant hardware renewal.

  • Giving developers back a sense of purpose — pride in creating leaner, faster, more elegant software.

In short, the death of Moore’s Law isn’t an end.

It’s the beginning of a new era — driven by the EROOM methodology.
