I started this rabbit hole looking at GPUs. Somehow I ended up researching zinc refineries. Welcome back to ADZ5150. 😂🐅 Everyone knows the AI arms race. NVIDIA GPUs. Hyperscaler capex. Gigawatt data centres. Power shortages. Memory. Cooling. But something caught my attention. In March, NVIDIA announced a US$2 billion investment in Lumentum. On the exact same day, it announced another US$2 billion investment in Coherent. US$4 BILLION. Not into another AI model. Not another GPU company. Into companies that make lasers and optical technology. And both agreements went beyond investments. They included multibillion-dollar purchase commitments and future access to manufacturing capacity. That made me ask the obvious GAZADZ question: 🐇 WHY DOES THE WORLD’S MOST IMPORTANT AI CHIP COMPANY CARE SO M
TSMC Profits Hit Record Highs — Why Is AI Hardware Still Being Sold?

Should investors follow TSMC’s capacity execution and Nvidia orders, or wait for clearer capex payoffs?
