You may be right. I'm sure you've heard of this guy who shares your views.
The answer to the next steps of evolution in screen technology is not to get bigger, but to get smaller and closer to the eye.
Step one will be some sort of a Google Glass type display which will project onto your retina. It has the advantage of complete portability while appearing as a giant sized display.
Step two will be a contact lens that does the same thing.
Step three will be an implant or they will come up with a way of transmitting signals through a skullcap or other type of technology.
This will be coupled with ever increasing synchronization between the phone/computer hardware and you, starting with near perfect speech recognition and moving eventually to implanted or skin contact direct interface with the brain.
Mankind will evolve into a cybernetic organism within the next century, and will likely leave behind the “meat sack” and become completely digital and mechanical immortal beings within the next 1000 years.
To paraphrase Arthur C. Clarke, if this seems preposterous, then just maybe I am close to predicting what may come. BTW, he predicted all of the above in his books.
