In pop culture, I’d say that zombies, vampires, super heroes, grim anti-heroes, basically anything that can go in to a comic book from the last fifteen years is being plastered all over movie screens from here to eternity.
I’d also say that there are other general trends as far as specific styles and tropes are concerned. Young Adult is now a booming business, where a lot of stories tend to take place in a dystopian future or dour alternate reality version of the present. A world with Ultratech in it doesn’t seem entirely dissimilar.
They usually tend to revolve around a young “so normal that could be me” type of character that finds out they’re special, which fits right in with out current self-narrating, selfie/vine/periscope society where everyone’s a unique snowflake with an interesting story to tell.
I don’t mean to mock that either. We’re a very self-obsessed culture now because for one thing, many can afford to be, so many people are in the self-actualization part of the hierarchy of needs. Plus the marketing (especially in the US) is geared toward satisfying yourself, treating yourself, getting something that you specifically should want or deserve, etc.
So how does all of that translate to KI?
Well, I could certainly see a sort of normal, everyman type of character that comes from a fairly ordinary background. A file clerk. A process server. Or if we’re going younger, a college student with a night job as a barista or telemarketer or whatever. I know, your eyes are already rolling back in to your head at the thought of a hipster Viking styled barista in KI. But I’m certain that there are ways of making an everyman type of character look and dress cool and fit properly in the realm of KI.
As for their story, well… Perhaps they get sucked in to a web of intrigue by Ultratech because they want him/her for a specific reason and this character eventually realizes that they have latent powers and their story revolves around finding out why, choosing who to trust, overcoming their fear, their wall-flower / loner nature to join the fight etc.
So yes, as strange as it sounds, I think that “average guy/gal” could actually be a pop culture trope that could be used in KI if done properly.
