Introduction
If you've ever wondered how AI works from the ground up, this guide breaks down the entire AI industry chain in simple, practical terms. From raw materials to smart robots, you'll learn how each part connects — and how you can find opportunities in this trillion-dollar sector.
1. Energy: The Foundation of AI
AI systems need massive amounts of electricity to operate. "The end of AI is electricity; the end of electricity is energy." New Energy (solar, wind, nuclear) and Fossil Fuels both play roles in powering AI infrastructure.
2. Chips: The Brain of AI
Chips are the "brain" of AI systems. How chips are made: raw sand (quartz) → purified to 11-nines silicon → melted into ingot → cut into wafers → etched with nanoscale circuits via ASML EUV lithography.
# Example: Check chip manufacturing equipment

- PCB (Printed Circuit Board): The "skeleton" connecting chips and components.
- MLCC (Multi-Layer Ceramic Capacitor): A "micro power bank" stabilizing voltage during AI operations.
4. Large Models: The Knowledge of AI
Large models (e.g., DeepSeek, Doubao) are the "knowledge base" of AI. They learn from massive data through: Data Collection → Data Processing (cleaned/labeled by "data processing workers") → Training (learning patterns to generate responses).
# Example: Train a simple AI model
model = train_model(data="cleaned_data.csv", epochs=100)5. Smart Robots: The Body of AI
Smart robots (robot dogs, humanoid robots) are the "physical body" of AI, allowing interaction with the real world. Current applications: tourism (performances), industry (manufacturing, logistics). Future opportunities: service robots (healthcare, education, customer service), industrial robots (assembly, maintenance).

常见问题
Which layer of the AI industry chain has the highest barrier to entry?
Chip manufacturing has the highest barrier by far. It requires ASML's EUV lithography machines (billions of dollars each, years of lead time, export controls), 11-nines silicon purification, and multi-billion-dollar fabrication plants. Only a handful of companies globally (TSMC, Samsung, Intel) can produce cutting-edge AI chips. By contrast, the large model layer has lower barriers in terms of capital — training a model like DeepSeek V4 costs millions, not billions — but requires rare AI research talent. The lowest barrier: data processing (cleaning and labeling data) and AI application development, which individuals and small teams can enter with modest investment.
How does the energy layer affect AI development?
Energy is becoming the binding constraint. A single GPT-5.6 training run consumes as much electricity as a small city. As AI inference scales to billions of daily users, the energy cost of running AI (not just training it) now exceeds training costs for most companies. This is driving: (1) nuclear power partnerships — tech giants are signing direct agreements with nuclear plants, (2) location strategy — data centers moving to regions with cheap renewable energy, (3) efficiency innovation — models like DeepSeek V4 Flash that deliver comparable performance at 1/36th the cost, which translates to 1/36th the energy. The energy layer isn't just about powering AI — it's shaping which AI architectures are economically viable.
What skills should I learn to enter the AI industry chain?
It depends on which layer you target. The guide gives three paths: Programming (Python, TensorFlow) for model development and AI engineering — the most versatile path, applicable to large models, robotics, and data processing. Data Analysis (SQL, Excel) for data processing and business intelligence — lower barrier, high demand, but more competition. Robotics (Arduino, ROS) for hardware-related roles — higher barrier (requires electronics knowledge), but less competition. The common foundation across all three: Python, basic statistics, and the ability to work with large datasets. The "AI Trainers" role (training and fine-tuning models) is the fastest-growing new job category in the chain — no single degree maps to it yet, making it accessible to self-taught learners with practical experience.
Is the AI industry chain a bubble, or a real opportunity?
Both — and the distinction matters for your strategy. The valuation layer (publicly traded AI companies) exhibits bubble characteristics: high P/E ratios, speculative narratives, and the expectation that "AI will change everything." The infrastructure layer (energy, chips, data centers) is real and growing — data center construction is at an all-time high, chip orders are backlogged for years, and energy demand from AI is measurable on national grids. The application layer (AI tools, agents, robots) is where real value is being created for end users, but where 99% of startups will fail. The guide's recommendation: invest in infrastructure (energy, chips), work in applications (where the jobs are), and learn skills that are transferable across layers (Python, data analysis, prompt engineering).
