I'm asking this out of sheer curiosity (and because opinions may be useful given that I mostly write in the sci-fi/speculative fiction genre) but where do you think mobile communication is heading? Mobile/cell phones. We started out in the early 90s with bricks, which were steadily reduced in size over the next ten years until we ended up with handsets not much bigger than a matchbox. And then Smartphones arrived and the industry decided to go backwards in terms of size, and now we're back to bricks... very flat bricks, but still bricks. All this makes me wonder where we'll be in 30-40 years from now. There's certainly no indication phones are going to start getting smaller again, but a future society where people are still walking around the streets staring at some form of communication screen seems unlikely to me (or maybe truer to say not as exciting). But what is the alternative? The remake of Total Recall suggested phones will be implanted in the palms of our hand, but to access the visual aspects of this device requires the user to find a flat plane of glass to press their hand against (not really practical, I think you'll agree). I suppose, thinking logically, you could argue the device itself can't really go anywhere in terms of design and how it's used, but functionality and capabilities most certainly can.
