I guess it's the argument of fun versus real.
It's not only science fiction. I for example study Asian studies. I won't elaborate but consider the fact that your Chinese around the corner serves food that is in fact almost nowhere in China to be found. That of course doesn't make the food bad. You can still enjoy it. Fantasy isn't probable at all, but still is enjoyed by many for the story.
If you read scifi for the realness, why not read scientific publications?
The fact about predicting the future is improbable in itself.

It's a matter of personal taste.
