I really think we're talking circles, as you've now just stated what we've said in the first place. SciFi authors thought of something that would be cool to have. Now, we have the tech that makes those scifi things real things. The people making the real things admit they were inspired by the scifi thing rather than it being an original idea to them.
Some of them admit of that and arguably the products would have happened even without sci fi. In some cases these are just marketing stories. I don't ever consume sci fi and I have been able to come up with ideas that someone might have seen in sci fi.
yes yes. you're brilliant. what's these supposed ideas that nobody else has come up with? it ain't braggin' if you can do it. otherwise, you're just some rando on the internet crying about how smart you are.
What's your point?
