Musk's G20 address: at least 15GW power shortfall for AI chips by 2027

Musk shared a Grok-generated summary of his G20 address:
- Power is already the bottleneck for AI, not a future one: consensus cited points to at least a 15 gigawatt shortfall in 2027 for AI chips.
- Diverging curves: AI chip production grows 40–50%/year while power outside China grows only 10–20% — the faster curve will overwhelm the slower one.
- SpaceX as compute landlord: Google, Anthropic and others already lease compute from SpaceX, which built its own power plants to bring capacity online fast.
- China has electricity but no latest chips due to GPU export bans; the real constraint is electricity growth outside China.
