What it is to be human is changing, and ever more quickly, even as we speak. Meaning computer-brain interface and brain to brain connection. So in a few years not to have that in a fictional future might seem really weird, like when we read a scifi book written in the 1890s and nobody has cars in the futuristic 1980s. Borg as something terrible might be really laughable to the augmented people watching TNG 10 or 30 years from now.
But we still read Verne and Welles and even Bradbury (who has guys smoking on one of his Mars missions, iirc - how stone age!) to gain insight into their conceptions of the future and - more importantly - their conceptions of the human adventure. Which is, after all, only beginning.
