I will write it one day. Right now other more fully-formed creative projects are taking precedence.
I do know that when I write it it'll be a different take, because it'll be my voice and perspective and a synthesis of the media that makes me, me.
But as they say, writing is hard. :)
My parent comment deals more with the idea that some fantastical sci-fi ideas or inventions become less fantastical the longer you sit on them. The idea for a touch-based slate computer in TNG was pretty cool! Now everyone has a tablet, and that took only about 20 years.
I don't believe other literary genres have this unique problem. If I came up with a Game of Thrones-esque fantasy story, I wouldn't need to worry about the worldbuilding becoming "outdated." (Maybe in esoteric cases like dinosaurs not having feathers before we discovered that they do, etc.)
Also, doesn't matter if it's been done before either. Lots of very popular books are quite similar to books published before them. Sci-Fi is not immune.
There's all sorts of memes about SciFi films that borrowed ideas and motifs from earlier works... but often when you did, it comes out that the earlier works also borrowed those pieces.
I had a similar thought, ideas are cheap. Loads of people are like "I have this GREAT idea for an app, I just need a developer to build it!"... as if the idea on its own has value.
Unfortunately and / or fortunately thanks to AI tech, anyone with an idea can now throw it at an AI and see it materialise.
Just write it if you want to.
