I think the trend in communication is towards concealment of technology. Same abilities, less footprint. Electrical wires are hidden in my walls, powering my devices. Plumbing, also hidden in the walls, brings me water and takes it away again. And phones are a little box that lets me talk to people that are thousands of miles away.
Back in the day, I remember, phones were larger. The size of my head, practically. The trend has been for smaller and smaller phones. I currently have a mobile phone about the size of two of my phlanges, which is way smaller than was seen as even possible when I was born.
Discovery is reporting that phones and remote controls may soon be replaced with a small unobtrusive hat that you wear and impose your will on your living room by your thoughts. It's another EEG project.
Or possibly more in the future. We may have cybernetic implants that let us think our way through a phone call, so you can reach the office by closing your eyes and concentrating. No more speaking aloud, which used to be necessary but will now just make you look like a tool. And controlling the TV? It already knows what you want to see and has tuned itself to the right station.
Okay, maybe no implants. Drunk calling is trouble enough on cell-phones, I don't wanna wake up tomorrow to find that I called Amenijad on my brain-implant and insulted him for several hours and now have a phone bill that costs more than a house.
But the possibilities are endless and amazing.
