Could just as well substitute "romance" or "thriller" or your genre of choice. As satire it was a bit tone deaf. Maybe the writer simply didn't like SF.
Anyways ...
I'm not sure there are compelling ways to flesh out setting. Or, there are a hundred thousand ways. The only rule of thumb I follow is that world-building never gets a whole paragraph. Setting can. There are places where it's absolutely necessary to describe a scene in some detail. One such place is to set up a scene for consequent action. You don't want to be describing the setting as your characters are fighting for their lives; at the same time, it might be vital to know the bookcase is just here, that there's only one door, that the floor is polished marble. Another such place is to set ambience; this is especially appropriate for fantasy, where readers want to hear about fantastic scenes. Here, my rule of thumb is never describe without at least one reaction. The reaction adds impact.
The standard fleshing out for SF is describing tech. To me, that's pretty analogous to the fantastic scene. It's part of why your reader picked up your story. In some cases (much more common in Golden Age SF), the rocket engine or the time machine gets described in detail because the mechanism is crucial to the story. Here again, break up the description with dialog and reactions., to give an emotional frame of reference for the reader.
I guess, more generally and succinctly: make sure to keep people in your story.
