One of the useful things about science fiction is that it creates a vehicle for presenting demos from the future to a broad audience. This matters because there are always restrictions on what we can build in any given year, yet we still want to be able to talk sensibly about the future.
In the case of computers, we have Moore’s Law, which suggests that computer capability grows exponentially over time. So we may not be able to achieve something in any given year, but we can predict with rough accuracy what we will be able to achieve a decade hence.
This principal can be applied to create plausible demos from the future. For example, Moore’s Law tells us that computer capability grows by roughly a factor of 100 in a decade.
If we were to take what we now know about machine learning, computer vision, computer graphics and other technologies used to support computer enabled human communication and multiply the speed of every component by 100, we could start designing a prototype for what a personal communication device might look like in 2031.
One of the best ways to deliver a sense of the capabilities of such a prototype into the public consciousness is through the medium of science fiction. Sounds to me like a fun project!
