Understanding the AI Infrastructure Stack

The AI revolution isn’t a single technology—it’s a complex stack of interdependent layers, each with its dynamics, bottlenecks, and power players.

To understand why this bubble is different, you must understand how these layers interact and constrain each other.

At the foundation lies the Energy Production Layer, the most overlooked yet most critical constraint.

AI data center spending has grown at least 10-fold since 2022, with Paul Kedrosky estimating that it’s approaching 2% of total U.S. GDP by itself.

This isn’t just about building more data centers—it’s about fundamentally reimagining our electrical grid for an era where computation becomes civilization’s primary energy consumer.

Above this sits the Physical Infrastructure Layer, where the battle for land, cooling, and connectivity plays out.

We’re looking at projected demand for 156 gigawatts of AI-related data center capacity by 2030, with 125 incremental gigawatts added between 2025 and 2030.

To put this in perspective, that’s equivalent to adding the entire power consumption of Japan to the global grid, just for AI.

The Compute Hardware Layer has become the most visible battlefield, where NVIDIA’s dominance meets desperate attempts at disruption.

NVIDIA’s data center revenue shot up a remarkable 217% in fiscal 2024 to $47.5 billion, but this success has painted a target on its back.

Every hyperscaler, every major chip company, and even startups are now racing to break NVIDIA’s stranglehold on the training market.

Moving up the stack, the AI Models Layer represents where software meets silicon in an explosive marriage of capability and constraint.

This is where the DeepSeek phenomenon emerges—the shocking realization that Chinese companies, constrained by export controls, are learning to extract more intelligence per FLOP than anyone thought possible.

Necessity isn’t just the mother of invention; it’s becoming the mother of efficiency revolution.

Finally, at the apex, the Application Layer promises to transform every industry, every job, every human interaction.

But here’s the paradox: the applications are ready, the demand is proven, the ROI is clear (or at least almost, as it’s a digital workforce), but we literally cannot build the infrastructure fast enough to deploy them at scale.
