Nvidia CEO Jensen Huang claims quantum computing is decades away, but is it really? The quantum era isn’t decades away — it’s unfolding in real-time.

Ah, simple times. Now we not only have machine learning—aka, supposed "artificial intelligence"—but also quantum computing, which uses microwaves to get qubits to do wacky and seemingly impossible things.

Quantum computing stocks sank on January 8, pausing a year-long rally, after Nvidia (NVDA.O) CEO Jensen Huang said the technology's practical use was likely two decades away. The long wait outlined by Huang for "very useful quantum computers" throws cold water on a sector that was already expected to
