Makes me think of Ada Lovelace and how awesome the mind can be when grappling with the abstract (though I'm sure non-quantum computers were still some help here to researchers for fiddling with quantum algorithms).
QC is currently basic research. It's not clear when machines large enough to be useful will exist, and I don't understand the reasons behind the current development speed. But keep in mind that we have computers with ~20qubits, and people have been consistently adding 3 more qubits every 2 years, for a rather long time.
