I think I have a pseudo explanation for why we can't predict what the future looks like (and I also mean that literally). Change happens from the bottom up, not from the top down. When a new radical idea takes hold and is adopted, it gradually becomes part of the system and is no longer a paradigm. You can only iterate so far on a current design before something else comes along to replace it. If you took the standard car design in the 1950s and tried to use it as a basis for what the future brings, well...you'd get roughly the same thing that you'd get if you took a Toyota and used it as the basis for what cars look like in the future. Have you ever noticed in the music in futuristic sci-fi movies? It's the same thing. You can't imagine what music sounds like in 50 years any more than you could have imagined rap or hip hop in the 1940's.
