1) I believe in lightsabers. The toy ones anyway...
I was a big Star Wars nerd for years, so I feel I can comment on lightsabers. First they are not lasers or even light based. They are plasma contained in a selective force field that is shaped like a rod. The force field is transparent to physical objects, but solid to energy and other force fields. I could see someone building one from a plasma torch with some kind of magnetic bottle field on the end to form the blade.
Another way to do the same thing is with a plasma inside a magnetic field that runs out along a rod of some kind. The rod would have to be able to take the plasma, and still produce the containment field. I agree with the poster that said this is completely possible, just horrendously expensive.
2) Time Travel also could be possible, just not into the past. Pushing people into the future would cause no paradoxes.
3) Instantaneous Quantum Teleportation I think will never be used on complex molecules. Would you really think it is OK to have your body destroyed and a complete replica rebuilt in some kind of matter printer somewhere else?
Wouldn't you call it teleportation if you used an laser to reduce an object, say a brass button, to nothing, one atom at a time, then record which atom was where and then send that data by a fiber optic or electrical wire to somewhere 1000 miles away, and have a CNC machine make the exact same part? Isn't it teleportation to type something on a website and have it read by others seconds latter? Does teleportation have to be instantaneous?
4) Did they say in Back to the Future how the hoverboard worked? I don't think so, so anything that flys or floats and has a skateboard shape is a hoverboard. And we all know such things exist.
It will not be long till we have wrist computers with 3D holographic displays.... I predict.

Here at Intel we make processors on 12 inch wafers. And, the individual processors on the wafers are called die. And, I am employed to check these die. That is why I am the DieChecker.
