I thinks most of the stuff that you saw in sci-fi films are getting reallity. Computares are faster and faster, the next step could be quantom computers. the "1" and "0" by electric signals are coming to a level that it will be difficult to go beyond, so why not go to atom tecnology? In theory it's possible, i thing it will be the next step. It will take some years.
and everythng is based on 1 or 0 ; on of off ; black or white.... all is done in 1 or 0. I wounder if it's possible to make something different, something were the base is not 1 and 0 but for example 1 ; 0 ; 1/2 ... we say that is not possible because electric signal is only on of off, but imagine something that you can have different states...
