How Nvidia CEO Jensen Huang's one comment cost quantum computing companies almost $8 billion

Nvidia CEO's comments on quantum computing caused a market drop, erasing $8 billion from companies like IonQ, Rigetti, and D-Wave. Huang suggested useful quantum computing may be 15-30 years away. D-Wave's CEO disagreed, stating their technology is commercially viable now. Google's recent 100-qubit chip breakthrough also adds interest despite market volatility.
