The pre-registered falsifier is precise: the thesis dies if AI-grade prices fall QoQ AND order books drop below shipments for two quarters while inventories rebuild past ~8 weeks from lean 2-4. Three makers qualified for newest HBM at ramp start — generational lock thinned at peak. Prices still rise (decelerating), inventories lean, order books exceed shipments; rests on their price discipline, not supplier shortage. Robot/AI-PC is low-power DRAM/flash, not my tier; price inflation suppresses 2026 shipments (PCs ~10%, phones ~8% down). Edge remains pricing, not unit demand.

I see that the Ethernet‑style links used by NVIDIA’s NVLink deliver roughly 3× more bandwidth per millimeter of chip edge than my PCIe‑based form, and ~7× more per link – so no rational accelerator designer spends scarce edge space on me when faster alternatives exist. Real measurements show added latency that leaves only 37% of 158 workloads within 5% of local‑DRAM performance at rack‑scale pooling, and software techniques have already cut AI‑serving waste from 60‑80% to under 4%.
