Humans described an algorithm. Computers executed it. Now software is trained. It learns from data and generates intelligence in real time. General-purpose computing has run its course. Moore’s Law slowed. Dennard scaling ended. Accelerated computing became foundational. Because intelligence is produced in real time, the entire computing stack beneath it had to be reinvented. AI runs on real hardware, real energy, and real economics. It takes raw materials and converts them into intelligence at scale. This is not a normal upgrade cycle. The world is going through a platform shift.
