I think the point being made is that the graphs don't show real world applications progress. Being 99.9999999% or 0.000001% of the way to a useful application could be argued as no progress given the stated metric. Is there a guarantee that these things can and will work given enough time?

Quantum theory predicts that they will work given enough time. If they don't work, there is something about physics that we are missing.

Quantum theory says that quantum computers are mathematically plausible. It doesn't say anything about whether it's possible to construct a quantum computer in the real world of a given configuration. It's entirely possible that there's a physical limit that makes useful quantum computers impossible to construct.

Sounds like a pursuit where we win either way
