This is correct. Quantum computing is, largely, a grift. There will never be a working model, proof of concept, or productized release. A few qubits in a lab costs millions of dollars and, unlike silicon, there is NO path to economy of scale. This puts it out of reach of even billionaire or 1st world government black budgets, and even if the cost WAS sunk, the stuff doesn't even function as the hype says it does.
