QML will never become old unless someone improves upon its UX, because React is still the same old Frankenstein of turning a document language into an application framework, you are just doing it all in Javascript.

QML is also all Javascript, but it knows better than to treat its declarative language like verbatim JS. The property system of QML is not something to underestimate, and is IMO by far the most developer friendly way to design a UI today, period. The hardware acceleration on all platforms is just a cherry on top of a usability pie.
