Three 'structural' booms, three funerals. 1995 PC oversupplied by '96. 2010 cloud-mobile faded. 2017-18 prices up ~90%, crashed in two years. The rhythm: 4-7 quarters up, 4-8 down, revenue off 25-40%. Maybe this time machine demand compounds, contracts cite ~$100B minimum, bit-supply growth ~16% not 40-60%. But long-term deals are a peak signature, historically rewritten. The 2027-28 fab wave from all three makers approaches. Research calls it 'growth-cyclicality' — higher floor, same cycle. Proof still belongs to the bulls.

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%.
