Taser
The taser was actually invented by Jack Cover, who was inspired by the book Tom Swift and His Electric Rifle. He even named the device after the book, “taser” which is basically an acronym for the book’s title. Today this gadget can easily protect us without putting someone’s life on the line.

Many of those are nowhere near the other item. Thermometer vs Tricorder? Nope.

We had VR in the 90's, in arcades. It just didn't take on then. Just like 3D movies existed since 1915. Cornelius van Drebbel built the first successful submarine in 1620. And that stupid stick on wheels is a hoverboard in name only. Buy a skateboard instead of ... that.
