Generally speaking, by the time a subculture such as steampunk secures the attention of major media, resulting in extensive coverage of the craze, said phenomenon is already on the way out.
Certainly the highest posthumous praise that can be conferred upon any writer is the assertion that his or her writing permanently altered the literary landscape for the better, opening new textual doors and engaging new readers. That the author's oeuvre was essential and irreplaceable and transformative.
Technically and logically speaking, actual Victorian science fiction writers cannot be dubbed 'steampunks.' Although they utilized many of the same tropes and touchstones employed later by twenty-first-century writers of steampunk, in their contemporary hands these devices represented state-of-the-art speculation.

The entire Internet, as well as the types of devices represented by the desktop computer, the laptop computer, the iPhone, the iPod, and the iPad, are a continuing inescapable embarrassment to science fiction, and an object lesson in the fallibility of genre writers and their vaunted predictive abilities.
The SF genre, of course, is really an organically evolved, marketplace-determined, idiosyncratic grab bag of themes and signifiers and characters and icons and gadgets, some of which hew to the realistic parameters and paradigms embraced by science, others of which partake more of fantasy and magic.
