I would think a Star Trek star replicator that moves around atoms and molecules to build stuff or use energy and covert it to matter to build stuff seems really far into the future.
Where Star Trek star replicator moves around atoms and molecules to make food and when done eating cleans the plate by removing atoms and molecules.

The Star Trek star replicator seems like it needs really advance nano technology and probably is 100 years out or more if it is even possible.
Other sci-fi and probably will not happen for long time if ever is star wars landspeeder.

This vehicle floats of the ground and cannot use fan,jet or propellers it requires anti gravity.
Other sci-fi and probably will not happen for long time if ever is nanites.
Really small tiny robots that patro your body and fix problems.

Other sci-fi and probably will not happen for long time if ever is spaceship.

They are really big and this would need anti gravity to take off from the ground and fly into space or would have to be build in space. They would also need warp drive because how else work you go from one star system to other star system that so far away.
Other sci-fi is going into space is really expensive and it probably to expensive for the middle class or even upper middle class and probably be only for the rich and wealthy.
