## Summary

Ben Bajarin and Jay Goldberg analyze Micron's transparent HBM roadmap, which dismisses 4F-squared memory in favor of vertical stacking to maintain a technology lead over Chinese competitors like CXMT. They discuss Meta's strategic advantage in owning massive AI infrastructure, enabling them to train and distill models like Muse at superior unit economics compared to API-dependent rivals. The hosts also examine NVIDIA's aggressive supply chain lock-up, debunking concerns about idle GPUs as standard staged integration, and warn of surging AI-powered cybersecurity threats.
