The Fourth Industrial Revolution: The Intelligence Revolution

The Data Center’s Role in Enabling the Intelligence Revolution

Innovation follows exponential curves. 

The First Industrial Revolution started in ~1760 and mechanized production - we moved from creating goods by hand to creating goods with machines. The Second Industrial Revolution (the Technology Revolution) started in ~1870 and was characterized by rapid industrialization, technological innovations such as electricity, the internal combustion engine, and the expansion of railways and telegraph networks, which further transformed economies and societies. The Third Industrial Revolution (the Digital Revolution), started in ~1960 and transformed industries with the advent of computers, digital technology, and the internet, revolutionizing how we process and share information. 

The time from the first to second industrial revolution was ~110 years. From the second to third was 90 years. As we stand on the brink of unprecedented advancements in artificial intelligence, I believe we’re just starting the Fourth Industrial Revolution: the Intelligence Revolution. And the time from the third to fourth industrial revolution was only ~55 years. From 110 > 90 > 55 years between industrial revolutions. AlexNet came out in 2012. Attention Is All You Need (which detailed the transformer architecture) came out in 2017. ChatGPT was released to the public in 2022. You could pick any of these dates as the start of the Fourth Industrial Revolution. Regardless, it’s fair to say we’re already ~5+ years into the Fourth Industrial revolution, with the majority of it still in front of us. I want to emphasize this point - we’re ONLY 5 years in. These industrial revolutions take decades. It’s exciting to think about the future we are walking in to. 

The Fourth Industrial Revolution, the Intelligence Revolution, will be defined by the transition from human-driven processes to AI-driven intelligence, transforming industries, economies, and daily life through the power of advanced computing. However, the infrastructure underpinning this Intelligence Revolution cannot be overlooked. Much has been written about Nvidia’s role in this with their GPUs. From A100s (Ampere Architecture), to H100s (Hopper Architecture), to the upcoming Blackwell chips. While the GPU is clearly an integral part of the Intelligence Revolution, there are many other components that all come together to create data centers - the foundational component of the Intelligence Revolution.  Data center buildouts are critical to sustaining and accelerating the development and deployment of the Intelligence Revolution.

This blog post explores eleven essential components of data centers, providing an overview and diving into the specific sub-components, their functions, and the companies leading in these areas. These 11 components include the below:

1. Servers 

2. Networking 

3. Storage 

4. Cooling 

5. Power Infrastructure (not including the power utility) 

6. Security 

7. Management and Monitoring 

8. Racks and Cabinets 

9. Cabling 

10. Environmental Controls 

11. Software

What’s most exciting to me is seeing how each one of these components will be reinvented for the Intelligence Revolution. We’re already starting to see a number of startups attacking different opportunities here and think we’re just at the beginning.

It’s important to call out that this post does not discuss two important bottlenecks in data center buildouts: real estate and power (and the relationship between the two). Modern data centers have significant power requirements - and a big challenge is finding real estate in close proximity with power sources. Why is close proximity important? Transmitting power from where it’s created to where it’s consumed (ie power plant to data center as a simple example) is not perfect. Power is lost along the way. This loss is primarily due to the resistance in the transmission wires, which converts some of the electrical energy into heat. The shorter distance power has to “travel” before it’s consumed leads to less “loss.” The challenge is that power was a bottleneck prior to the AI craze. And a lot of the best (ie closest proximity to power) real estate is spoken for. We’ll really need to see breakthroughs in nuclear generation, solar storage or alternative forms of energy. “On Site” generation is HUGE topic amongst folks in the data center world. Climate considerations aside, natural gas could actually play a big role (so I’m told). 

And with that - here’s how I break down the core components of a data center
