Artificial intelligence is one of the most powerful forces shaping the world today. It’s not just a clever application or a single model; it’s infrastructure like electricity and the internet.

AI runs on real hardware, real energy, and real economics. It takes raw materials and transforms them at scale into intelligence. Every company will use it. Every country will build it.

To understand why AI is developing this way, it helps to start from first principles and examine the fundamental changes happening in computing.

From Pre-Recorded Software to Real-Time Intelligence

For most of computing history, software was pre-recorded. Humans described an algorithm. Computers executed it. Data had to be carefully structured, stored in tables, and retrieved through precise queries. SQL became indispensable because it made that world feasible.

AI breaks this pattern.

We now have computers capable of understanding unstructured information. They can see images, read text, listen to sounds, and understand meaning. They can reason about context and intent. Most importantly, they can generate intelligence in real time.

Every response is newly created. Every answer depends on the context you provide. This isn’t software retrieving stored instructions. It’s software reasoning and generating intelligence on demand.

Because intelligence is produced in real time, the entire underlying computing stack must be reinvented.

AI as Infrastructure

When viewed from an industrial perspective, AI can be broken down into a five-layer stack.

Energy

At the bottom is energy. Real-time generated intelligence requires real-time energy. Each token generated involves electron movement, heat management, and energy conversion into computational results. There are no abstractions beneath this. Energy is the first principle of AI infrastructure and a hard constraint on how much intelligence the system can produce.

Chips

Above energy are chips. These processors are designed to efficiently convert large amounts of energy into computation at scale. AI workloads demand massive parallelism, high-bandwidth memory, and fast interconnects. Advances in chip technology determine how quickly AI can scale and how cheap intelligence can become.

Infrastructure

Above chips is infrastructure. This includes land, power delivery, cooling, buildings, networks, and systems that orchestrate tens of thousands of processors into a single machine. These are AI factories. They are not designed for storing information—they are designed to produce intelligence.

Models

Above infrastructure are models. AI models understand multiple types of information: language, biology, chemistry, physics, finance, medicine, and the physical world itself. Language models are just one category. Some of the most transformative work is happening in protein AI, chemical AI, physics simulation, robotics, and autonomous systems.

Applications

At the top is applications, where economic value is created. Drug discovery platforms. Industrial robots. Legal assistants. Autonomous vehicles. An autonomous vehicle is an AI application embodied in a machine. A humanoid robot is an AI application embodied in a body. The same stack, different outcomes.

This is the five-layer cake:

Energy → Chips → Infrastructure → Models → Applications.

Every successful application pulls on every layer below, extending down to the power plants that sustain it.

We are just beginning this construction. We have only invested hundreds of billions of dollars. We need to build trillions more in infrastructure.

Globally, we are witnessing the unprecedented construction of chip factories, computer assembly plants, and AI factories. This is becoming the largest infrastructure build in human history.

The workforce needed to support this is enormous. AI factories require electricians, plumbers, pipefitters, steelworkers, network technicians, installers, and operators.

These are skilled, well-paid jobs, and demand currently exceeds supply. You don’t need a PhD in computer science to participate in this revolution.

Meanwhile, AI is driving productivity across the entire knowledge economy. Take radiology as an example. AI now assists in reading scan images, yet demand for radiologists continues to grow. This is not a paradox.

The goal of radiologists is patient care. Reading scans is just one task. As AI takes on more routine work, radiologists can focus on judgment, communication, and care. Hospitals become more efficient. They serve more patients. They hire more staff.

Productivity creates capacity. Capacity drives growth.

What has changed in the past year?

In the past year, AI has crossed an important threshold. Models have become good enough for large-scale deployment. Reasoning ability has improved. Hallucinations have decreased. Grounding has significantly improved. For the first time, applications built on AI are beginning to generate real economic value.

Applications in drug discovery, logistics, customer service, software development, and manufacturing have demonstrated strong product-market fit. These applications are heavily pulling on every layer below.

Open-source models play a key role here. Most models worldwide are free. Researchers, startups, enterprises, and entire nations rely on open models to participate in advanced AI development. When open models reach cutting-edge levels, they don’t just change software—they activate demand across the entire stack.

DeepSeek-R 1 is a powerful example. By making a strong reasoning model widely available, it accelerates adoption at the application layer and increases demand for training, infrastructure, chips, and energy below.

What does this mean?

Viewing AI as critical infrastructure clarifies its implications.

AI begins with a transformer large language model. But it’s much more than that. It’s an industrial revolution that reshapes how energy is produced and consumed, how factories are built, how work is organized, and how economies grow.

AI factories are being built because intelligence is now generated in real time. Chips are being redesigned because efficiency determines how fast intelligence can scale. Energy becomes central because it sets the upper limit on how much intelligence can be produced. Applications are accelerating because their underlying models have finally crossed the threshold to large-scale usefulness.

Each layer reinforces the others.

That’s why the scale of construction is so immense. That’s why it touches so many industries. That’s why it won’t be confined to a single country or sector. Every company will use AI. Every country will build it.

We are still in the early stages. Most infrastructure does not yet exist. Most workforce skills are not yet developed. Most opportunities are yet to be realized.

But the direction is clear.

AI is becoming the infrastructure of the modern world. The choices we make now—how fast we build, how broadly we participate, and how responsibly we deploy—will shape the face of this era.
