Computing.

Geometric blend: processing ($/GFLOPS, 60%), disk ($/GB, 30%), RAM ($/GB, 10%).

buys: 8,130 GFLOPS (8.1 TFLOPS)

Then: A GFLOP of compute cost roughly a million dollars. A gigabyte of disk: $9,000.

Now: A penny buys the GFLOP; the gigabyte costs one cent.

Moore's Law, then GPUs, then the AI accelerator boom — a roughly nine-million-fold composite decline, the steepest in economic history. One honest wrinkle: memory and storage prices turned UP in late 2025 on AI datacenter demand.
