## Nauti's Take

The opportunity sits in the memory question: stacking DRAM directly on the wafer could remove the exact bottleneck that inference workloads hit today. The risk is the gap between roadmap and shipping hardware, because CS-6 is an announcement rather than a product. Relevant for anyone planning inference capacity outside Nvidia, while everyone else can treat this as a watch item for now.
