This is not science fiction, but a distorted nostalgia for a past that never was. I am surprised that Orwell stopped with the steel pen and that he didn't have Winston writing with a neat goose quill.
Nor was Orwell particularly prescient in the strictly social aspects of the future he was presenting, with the result that the Orwellian world of 1984 is incredibly old-fashioned when compared with the real world of the 1980s.
Orwell imagines no new vices, for instance. His characters are all gin hounds and tobacco addicts, and part of the horror of his picture of 1984 is his eloquent description of the low quality of the gin and tobacco.
He foresees no new drugs, no marijuana, no synthetic hallucinogens. No one expects an s.f. writer to be precise and exact in his forecasts, but surely one would expect him to invent some differences.
In his despair (or anger), Orwell forgets the virtues human beings have. All his characters are, in one way or another, weak or sadistic, or sleazy, or stupid, or repellent. This may be how most people are, or how Orwell wants to indicate they will all be under tyranny, but it seems to me that under even the worst tyrannies, so far, there have been brave men and women who have withstood the tyrants to the death and whose personal histories are luminous flames in the surrounding darkness. If only because there is no hint of this in 1984, it does not resemble the real world of the 1980s.
Nor did he foresee any difference in the role of women or any weakening of the feminine stereotype of 1949. There are only two female characters of importance. One is a strong, brainless 'prole' woman who is an endless washerwoman, endlessly singing a popular song with words of the type familiar in the 1930s and 1940s (at which Orwell shudders fastidiously as 'trashy', in blissful non-anticipation of hard rock).
The other is the heroine, Julia, who is sexually promiscuous (but is at least driven to courage by her interest in sex) and is otherwise brainless. When the hero, Winston, reads to her the book within a book that explains the nature of the Orwellian world, she responds by falling asleep - but then since the treatise Winston reads is stupefyingly soporific, this may be an indication of Julia's good sense rather than the reverse.
In short, if 1984 must be considered science fiction, then it is very bad science fiction.
