What do cell phones look like in the year 2144?
Obviously they won't have a screen anymore. They'll be pop-up displays. So if you're sitting on a train and your romantic partner sends you a steamy selfie...guess who has an audience?
Has this annoyed anyone else?
If they're tactical screens, that makes sense. But I still don't think transparent displays on personal devices will be a thing in the future.
Have you ever been in a takeaway place or a waiting room where someone is listening to music or watching videos on speaker? What about a lunatic who is walking through Target yelling into their speaker phone? Or, my favorite, some dumbass who decided he needed to have a video call with his girlfriend in a locker room.
People would have zero issues looking at risque pics or having loud conversations into their phone.
That said: Many sci-fi lore books will explain that those are usually representations of what the person is seeing. They aren't holding up a hologram. They are holding up a device that beams that directly into their eyes so only they can see it... that they are still holding at a weird angle so that the camera doesn't get a weird shot.
