Ahem.

The liquid helium isotopes needed to power the heat pumps are extremely expensive, don't last very long, extremely difficult to transport, and extremely dangerous to use. And even if you extremely careful and do everything right like a proper scientist while operating the thing it could still easily experience decoherence and become worthless in an instant.

There was a time when people thought that nuclear technology was going to be in everything. Your home would have a nuclear reactor and we'd never need power lines again! Your car would run on a nuclear reactor and have a range of thousands of miles! There was even a concept car that was designed for it (with the cab as far away from the reactor as possible to protect from radiation, cute). A lot of people assumed it would become safe, even though it was dangerous by it's very nature. Surprise, nuclear technology isn't being used in every home. Why? Because it's dangerous and expensive and time will not change that. Quantum Computing is similar. The requirements to make it work are obscenely difficult and hazardous, and it requires massive operations to get anything done. Even the slightest mistake and it's all for not. And remember, despite all the research, they aren't working on anything beyond a bit by bit level yet (and even that is contested). For them to become safe would require a math/physics breakthrough and/or much more advance technology. I.e. probably well beyond our lifetimes. And then it could end up like atomic energy, and never be useful without massive teams to manage them and tons of safety precautions.

Even the earliest analog and digital computer systems were simple(ish) to operate. Giant behemoths of insane complexity, but anyone with a couple of weeks training could operate and maintain them safely and efficiently. Quantum computers need hundreds of theorectical physicists with doctorates to simply operate these things. Not to mention the expensive exotic raw materials that are required for them to work (which time won't make more plentiful) and the hazards involved in their handling. Quantum technology definitely seems like it's following the nuclear energy model to me.

And that's assuming quantum computers ever become useful in general computing tasks. Quantum Computers do not work the same way that our computers do; it's extremely difficult to get them to do ordinary things. Most of the potential for quantum computing is in areas of extreme science that our current computing technology struggles with or simply can't do yet, like simulating other forms of theoretical physics (Boson Sampling).
