I think many of us have seen at least the odd Star Trek Episode or Movie.
Although 'only' Science Fiction, it's somewhat surprising how many gadgets have come from this show in to our everyday lives, eg, the original Motorola Flip Phone was modeled on the Communicators used in this series.
I have read in a few journals now that the Transporters they have are possible for inanimate objects, though take a lot of energy to operate.
While looking for cylinder heads today, I stumbled on to a 'Replicator', which I think, since the advent of 3D Printing, many could see wasn't too far away. This still only appears to be only in a single material, but to me at least, is a further advancement / leap forward from 3D printing;-

The long held dream of long (very long) distance space travel will rely on these kinds of technologies to make it possible. Tools and spares will no longer need to be taken as they will be able to make them on-route.
Wonderful technology.
