Submarine
In the book Twenty Thousand Leagues Under the Sea, the adventures were all in a submarine. While not everyone at that time knew whether this type of transportation would ever possible, it was considered fiction. However, today we have modern submarines that can do a lot more than just travel underwater.

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.
