You're really talking about "hard sci-fi" there, when you talk of the earlier stuff.
Not so much Wells because that really was early, but the mid-20th century stuff was all about the science.
I know what you mean about how things have changed, but just last night I read a great tale from that Bradbury collection called
"The Murderer".
Rather than have me try to explain it, the plot summary on Wiki does it superbly :
The scene is set in the near future, in an apparently sterile and clinical building. There is music coming from every direction; each person, it seems, is listening to classical music, talking on a phone, using a computer, or communicating constantly in some other way. Most people seem to be engaged in several of these activities at the same time.
A psychologist exits the noisy environment to confront a patient confined to a small safe-room. The psychologist notes that the man has ripped the radio out of the wall to silence it. The room seems unnaturally quiet to the psychologist, yet the patient seems perfectly at ease, even happy. The patient calls himself 'the Murderer', and demonstrates his murderous ability by destroying the psychologist's wristwatch radio.
Questioning reveals that the man had one day been driven mad by the constant expectations of communication inflicted upon him by society - his wife and children could speak with him whenever they wished, wherever they were; any person could call on him, and many did, simply to make use of their communications devices. He gives a striking image of a world in which humans are constantly bombarded by music, advertisement, propaganda and communication. He then describes his revelation; that if he shut off his phone, he could not be bothered by it. When he arrived home on that day, he discovered his wife, frantic at being out of touch with him for so long. This apparently drives home to him their terrible addiction to technology of communication. He begins to destroy things - his phone, his wristwatch, the television, any thing that could disrupt the peace he seeks. The man regrets only destroying the 'Insinkerator', which he used to mangle another piece of equipment. The Insinkerator, a sink drain disposal, he says, was a machine with a good solid purpose which did not disturb him with its functions, did not demand his attention, which only functioned when he asked it to.
The man then describes his wonderful state of calm and relaxation, moments of total freedom of all responsibility and worry inflicted upon him by machines. The psychologist makes due note of this, prompting him with questions, even seeming to perhaps understand what the man feels. At the end of the Murderer's tale, however, the psychologist steps back into the world of music and talk, quickly relaying information on the man's condition to an aide over another communication device, and re-immerses himself into the glare of technology's power.
I think that's staggeringly prophetic, don't you ??
The vision of the man ..
Just to reiterate : this was written in
1953.
There's a few hard sci-fi titles I would recommend to anyone as tasters and if you don't like them you probably won't like the genre in general (a bit like suggesting Miles Davis'
Kind Of Blue album for anyone who thinks they might enjoy jazz but don't know where to start) :
ARTHUR C CLARKE - Rendezvous With Rama (my all-time favourite sci-fi)
ROBERT HEINLEIN - Stranger In A Strange Land
LARRY NIVEN - Ringworld
ARTHU C CLARKE - Childhood's End
