Episode notes
Gemini 3 Shifts The Competitive Baseline
- Google launched Gemini 3 and leveraged massive TPU compute to beat OpenAI on benchmarks.
- That success threatens OpenAI's lead and reframes NVIDIA's role in AI infrastructure.
TPUs For Sale Change The Chip Market
- Google is selling TPU capacity to rivals like Anthropic and Meta to challenge NVIDIA.
- That move creates a viable alternative to NVIDIA and pressures NVIDIA's long-term margins.
CUDA's Moat Is Vulnerable To Hyperscalers
- NVIDIA's historical advantages were performance, flexibility, and CUDA ecosystem.
- Hyperscalers have the scale and incentive to build alternative stacks and reduce CUDA lock-in.
