HunchBluntley: Not if the setting hasn't got any actual punk aesthetic to it -- then it's just misleading. And that's the case with the vast majority of such cases that I've seen. (
Frostpunk is a pretty egregious example.)
MobiusArcher: You have missed the point. Language doesn't work the way you think it does. The meaning of words changes over time. People like to think that the dictionary defines the words, but it just collects the words in use at the particular time its printed. That's why they put out a new one every year. They have to update words, because they have new meanings.
I'm not going to go on a tangent as much as I'd like, given that we're already going a bit off-topic. Suffice it to say that there is good linguistic change, and bad.
Good change fills unmet needs, gaps in the vocabulary (or other parts of language). Bad change is change for change's sake, change which overwrites or removes useful words or specific meanings, replacing them with newer, vaguer ones -- or worse, with nothing at all. Bad linguistic change is almost always thoughtless. "Language changes!" tends to get used (a lot) as an excuse to avoid actually evaluating a given change -- to excuse that thoughtlessness.
Both kinds of change are inevitable
in general,
in the long term, but that doesn't mean that one shouldn't push back against
individual changes that one sees as pointless or harmful. In my view, this particular change is pointless. Not harmful in any serious way, but valueless and, therefore, annoying. :)
As a parting thought, I'll note also that, of all these derivative variants of "cyberpunk", only "steampunk" has actually (as far as I'm aware) caught on or become a "thing". Most of the rest seem to be just so much marketing fluff, contrived and used only by the creator(s) and/or marketers of a given product, seemingly in the hope that it will help differentiate their product from others. I'm always uneasy about marketing and corporate-middle-management speech leaking into everyday, mainstream language.
