Sometimes I read modern sci-fi and they still make certain things look futuristic even though they have been already invented in the real world. I’m not really talking about retroscifi like in Star Wars BUT speaking of Star Wars, in the 2016 Star Wars novel Bloodlines, moving sidewalks were highlighted (slightly) as being a big thing. Yet, they can easily be made (they just aren’t everywhere because they are hazardous and an accident waiting to happen). VR isn’t in this category though because the version we have sucks and we don’t have the good stuff yet
Anyways, can you think of any other examples besides moving sidewalks?
I feel like a lot of countermeasures and targeting systems we've had since the 60s are still considered absolutely cutting edge in most mil-fi.
Also biometric scanners.
