Flying cars. Battling robots. Holograms and virtual reality. These are all devices that might have started out as pieces of sci-fi technology, but over time, these seemingly wacky ideas have turned into reality.

There's some sci-fi tech from movies and TV we wish were real, but there are other sci-fi inventions that are best left to the screen. Sure, some of these sci-fi technology ideas sound good in theory - who wouldn't want a self-drying coat like in Back to the Future Part II or extra storage in their brain like in Johnny Mnemonic? But if you really think about these sci-fi gadgets, they are impractical, dangerous, or plain unnecessary.
