Maybe a better approach would be to consider how you'd try to convey the same information to a reader 50 years in the future, when "modern" may mean something very different to them. What does that actually mean, specifically? What are the good and desirable qualities the term's intended to express to the reader? It's not a good word for communication because it's both vague to begin with, and heavily abused in marketing, so people's ideas of what it might mean vary wildly—it's so lacking in specificity that it may as well be a made-up nonsense word, as far as how much information it carries.
