China building 38 nuclear reactors (~39.8GW) as energy emerges as AI's biggest bottleneck
kimmonismus · x · 2026-10-11
Citing an a16z chart, kimmonismus argues energy—not compute—is AI's real bottleneck: China generated half the US's electricity in 2005 but now produces over 2x. China is building 38 new nuclear reactors with 39.8GW combined capacity, while the US mostly bets on small modular reactors, with solar widening the gap further. The future of AI, he says, will be decided by grid expansion and energy scaling, where China holds a clear lead.
