Don't you mean "in the near future"? Or do you think that quantum computing will prove to be too expensive or surpassed by a different technology before it ever becomes scaled sufficeintly?

It's already surpassed by conventional techniques, and if both conventional and quantum techniques stick to their current rates of improvement then it always will be.

Also, it may turn out to be fundamentally impossible to run a 50-qubit machine without decoherence killing it...
