Well we built the nuclear sub like the Nautilus, we went to the moon, and from Edger Rice Burroughs and Tesla we have wireless energy transmission in a rudimentary form.
We have drones up the yazoo, I’m thinking of the Master of the World, not quite the scale of a flying aircraft carrier but getting there.
Still haven’t found Barsoom on Mars, let alone landed on it. Still missing the time machine of Wells. Verne said we’d use a gigantic cannon to fire people to the Moon and that didn’t happen. We still haven’t been able to journey to the center of the earth. You can Google all the things he wrote about that didn’t happen - Verne didn’t actually get all that much right.
Also, in 20,000 Leagues, the Nautilus is powered by *batteries* - in fact, it’s specifically mentioned to be a special kind of conventional wet cell battery. Not nuclear power.
Disney changed that when they made the movie in the Atomic Age.
Wireless energy transmission turned out to have so many downsides that humanity decided it was a horrible idea and decided not to use it. Radio and indeed most electromagnetic communications are practically impossible in an area that a Tesla wireless power transmission system is being used.
