Day 2 talk by Tristan Nitot (Octo): How can we run tomorrow's services on yesterday's computers?

Summary

The speaker discusses Moore's Law, which has driven the rapid advancement of hardware, doubling transistor counts every two years. However, software development has not kept pace, resulting in inefficient, bloated programs that waste the power of modern processors. The speaker highlights how optimizing software can lead to significant resource savings, drawing from real-life examples. The presentation emphasizes the need for better software craftsmanship to maintain performance, reduce environmental impact, and foster innovation. Ultimately, optimizing software rather than continually upgrading hardware could mitigate digital waste and preserve planetary resources.

Takeaways

• 😀 Moore's Law, formulated by Gordon Moore in 1971, states that the number of transistors on a semiconductor doubles every two years, fueling the rapid growth of hardware performance.
• 😀 However, software has not kept pace with hardware, growing slower faster than hardware improves, leading to inefficient and bloated software systems.
• 😀 The growth of software bloat is exacerbated by the tendency of companies to prioritize adding new features over optimizing existing code, resulting in slower products over time.
• 😀 A shocking example: modern computers running Windows are up to 5 times slower than older systems like the Apple II, just to display a character on screen.
• 😀 The environmental impact of digital products is significant, with hardware manufacturing consuming resources like water, minerals, and energy, contributing to climate change and biodiversity loss.
• 😀 Climate change is an urgent global issue, with rising CO2 levels and more frequent extreme weather events, making the need for sustainability in tech even more critical.
• 😀 A key driver of software inefficiency is the expensive nature of developer time, leading to a preference for new features over optimization, despite the availability of greater computing power.
• 😀 The speaker proposes 'E’s Law,' a reverse of Moore's Law, suggesting that if we optimize software by a factor of two every two years, we can avoid further environmental harm by not needing to manufacture new hardware.
• 😀 By optimizing software, we can free up existing computing resources, avoiding the environmental cost of building new hardware and maintaining innovation without further exploitation of natural resources.
• 😀 Real-world examples, like Python scripts optimized 60 times faster and machine learning tasks reduced from 15 hours to 10 seconds, show that significant performance improvements are possible with focused optimization.
• 😀 The future of digital progress lies in improving software efficiency through better coding practices, software craftsmanship, and identifying the most inefficient parts of code for optimization.

Q & A

What is Moore's Law and how has it shaped the technology industry?

Moore's Law, proposed by Gordon Moore in 1965, states that the number of transistors on a chip doubles approximately every two years. This law has driven exponential increases in computing power, leading to faster, more powerful processors and enabling major advancements in technology over the last few decades.

What is the paradox highlighted by Nikas Law in contrast to Moore's Law?

Nikas Law suggests that software is becoming slower at a faster rate than hardware is becoming faster, meaning that despite the rapid advancements in hardware, software often fails to keep up, becoming bloated and inefficient.

Why does the speaker suggest that software optimization is often overlooked in favor of new features?

The speaker argues that because hardware is constantly improving, developers often choose to add new features instead of optimizing existing software. Optimization takes time and effort, but new features can immediately make products more attractive, which is often seen as more important in a competitive market.

How does the speaker explain the environmental impact of the tech industry?

The speaker highlights that the majority of the environmental impact in digital technology comes from the manufacturing of hardware, not the running of software. Hardware production consumes significant resources, such as water, minerals, and energy, contributing to climate change and resource depletion.

What are the key environmental consequences of the growing demand for new tech products?

The continuous demand for new hardware leads to increased resource extraction, energy consumption, and pollution. This contributes to climate change, biodiversity collapse, and the depletion of vital natural resources, exacerbating environmental crises.

What is E's Law and how does it relate to Moore's Law?

E's Law is a reverse of Moore's Law, suggesting that we can optimize software at a rate similar to Moore's Law—doubling software efficiency every two years. The goal is to improve software performance without requiring new hardware, thereby reducing the environmental cost of manufacturing new devices.

How can software optimization help mitigate the environmental impact of technology?

By optimizing software to run more efficiently on existing hardware, we can reduce the need for new devices. This leads to less manufacturing, less resource extraction, and ultimately a lower environmental footprint for the tech industry.

Why is software craftsmanship important in addressing the issues raised by the speaker?

Software craftsmanship, or the focus on writing efficient, maintainable, and high-quality code, is crucial for improving software performance. By training developers to write better code, we can reduce inefficiencies, cut down on resource consumption, and ensure that software continues to improve without relying on new hardware.

What is the impact of bloated software on system performance?

Bloated software consumes more resources—such as memory and processing power—than necessary, leading to slower performance. This inefficiency is exacerbated over time as more features are added without regard for optimization, resulting in a poor user experience and increased environmental costs.

How does the speaker view the future of Moore's Law in relation to hardware development?

The speaker believes that Moore's Law has largely plateaued, as the speed and efficiency gains of processors have slowed down since around 2011. While transistors are still being packed more densely, the cost of each new transistor has stabilized, signaling the end of the rapid improvements predicted by Moore's Law.
