In most sci-fi literature, the 'human bias' is very visible in every aspect of fictional universes.
Here are some examples.
Future technology is just a modified version of today's items. In 2001, a space odyssey, tablets are just minified televisions. In the eighties, smart watches were imagined as minified fully fledged computers, complete with tiny floppy disks and QWERTY keyboards!
Oh, and don't forget those posters from 1900s artists imagining life on the year 2000. They're absolutely amazing!
What about extraterrestrial civilisations?
Alien species are inspired, if not almost identical to, terrestrial humans, animals and plants. Intelligent species communicate mainly by talking and writing; they eat; and not only they have feelings, but they also experience the same set of feelings as humans. And they, too, invented computers! What a coincidence!
Even alien societies aren't that alien after all. Just like here, they have families and they need some sort of central leadership (or any leadership, for that matter).
Needless to say, some human languages, spoken by many peoples on Earth, are more alien (compared to English) than invented languages.
Maybe the most tricky part is the physics. Although occasionally ignored to make room for some impressive stunts, fictional universes rely, almost always, on the same laws that rule our own (I'd love to see what would a triple-charged world look like!).
THE QUESTION
Is this familiarity with our own world intentional to make the audience comfortable with the whole set and make sense of it, or it's just some sort of lack of imagination?
