Hoverboard
All 3 Back to the Future movies were about a technology that we can still only imagine, a time travel machine. But in the second part of the movie, they showed what they think the future will look like. There have been hoverboard prototypes and we can’t wait to try one in the future.

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.
