AI runs on real hardware, real energy and real economics. It takes raw materials and converts them into intelligence at scale. Every company will use it. Every country will build it. To understand why AI is unfolding this way, it helps to reason from first principles and look at what has fundamentally changed in computing.
From Prerecorded Software to Real‑Time Intelligence For most of computing history, software was prerecorded. Humans described an algorithm. Computers executed it. Data had to be carefully structured, stored into tables and retrieved through precise queries. SQL became indispensable because it made that world workable.
AI breaks that model.
For the first time, we have a computer that can understand unstructured information. It can see images, read text, hear sound and understand meaning. It can reason about context and intent. Most importantly, it generates intelligence in real time.
