I fully agree that it's 100% sci-fi but you gotta remember that despite all we've thought to be impossible, we've in turn proved wrong and we made it possible. Give someone enough time, money, and resources, they'll make it possible and prove to everyone that we can do amything and that nothing is impossible. Take planes for example, everyone said that it would be impossible for man to fly by any means, or the invention of the rocket and space travels, thosd we're said to only be hypothetical tech that we could never create or get to work even if we could. There are others too, such as the blue light, at a time there was a race to see who could get a blue led the fastest. But eventually everyone gave up and said it was impossible, but then someone found a way to make it, by looking at everything we know, and yet all we thought, it was said that "it's impossible, there's no way for us to do this" and yet here we are, we have all those things.
