@gsuberland that's a good way of putting it, and one of the reasons quantum has been difficult for me to find anything fascinating enough about to learn and play around with.
I know there are some simulators we can access to get an idea of how to throw problems at it, but it's a domain very few of us have an ability for hands-on.
As soon as I realized you don't run a shell or OS on a quantum computer, it became a peripheral in my mind.
In this case, my mind believes it's just a matter of having a peripheral with enough qubits to tackle the numbers that need to be processed -- like going from 32 bit to 64 bit registers.
So it seems probable to me that if they can handle a 50 bit number and the decoherence/noise to make it useful, it's simply a matter of scaling up that register.
Maybe it takes 4x the qubits to go from 50 to 51 bits, but eventually, someone will build a large enough register to hold the data that needs to be factored / worked on.
