Although i would like to point out that things like Jarvis from iron man, holographic phones, power armour are in fact real. The cubic is miles better than what the crappy Siri is, if you happen to look it up on YouTube it's pretty badass. There's a holographic phone that's using 4 cameras to follow your eyes and produce a image seemingly in 3D above your phone giving a holographic effect. Power armour is from a mix of Exo Skelton armour and extreme high impact resistant bear armour adapted for armed forces. Teleportation is also invented already as they have already tested it on electronic and small atoms, but the information to transport a person would take decades so it's invented but a impossible reality. There is some cool inventions out there that people don't even know exist however most are in experiment stages or isn't made open to the public due to paper work, money to produce or just a secret. Wouldn't surprise me if they've already made clocking generators with a artificial intelligence death machines that are being used to fight off hordes of aliens.
