I don't really disagree, but to be fair, there are more than a few limitations that need to overcome before the killer app can even be considered. We have enough hints to know we're in the right direction. A lot of the recent Quantum articles I've seen have been specifically about getting past those hurdles. A big one, for example, is developing qubits that are stable for a long enough duration to finish a computation and evaluation. Some advances have looked at different lasers. Some have discovered interesting/new magnetic effects that were previously unknown. Some are working with single(ish) molecule layers of various metals and other elements. And so on. And that's all just to tackle one specific hurdle. So I don't really see any reason for shame. Nobody is expecting to see anything truly revolutionary from a quantum computer yet. But without all the inputs and attention given to the intermediate results, we'd never get there either.
