What are the real world use cases now, today? The only thing I see in the QC space, are QC stocks and funding paying for the employment of scientific experimentation, which isn't a real world application.
Do I have to wait 15 to 30 years for a series of real world changing breakthroughs that I can already do on a NVIDIA GPU card?
That doesn't exponential at all, in fact that sounds very very bearish.
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 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.
Quantum theory says that quantum computers are physically plausible. Quantum theory lies in the realm of physics, not mathematics. As a physical theory, it makes predictions about what is plausible in the real world. One of those predictions is that it's possible to build a large-scale fault tolerant quantum computer.
The way to test out this theory is to try out an experiment to see if this is so. If this experiment fails, we'll have to figure out why theory predicted it but the experiment didn't deliver.
Publishing findings that amount to an admission that you and others spent a fortune studying a dead end is career suicide and guarantees your excommunication from the realm of study and polite society. If a popular theory is wrong, some unlucky martyr must first introduce incontrovertible proof and then humanity must wait for the entire generation of practitioners whose careers are built on it to die.
