The whole "getting augmentations makes you lose your humanity (soul) bit by bit" thing doesn't show up in any of the foundational cyberpunk novels. In fact, it doesn't show up in any cyberpunk novel I've read, and I've read a fair few.
I'm fairly sure this is a purely tabletop-world concept that has wormed its way into other media a little bit.
I don't know how much people realize this when discussing the genre.
It’s definitely a game thing originally.
Introduced in the Cyberpunk TTRPGs, and purely there to balance out having all these mechanical augmentations so player who wanted to play cyborgs weren’t just inherently stronger than those that didn’t.
But any trend in TTRPGs will influence the next generation as authors as the Venn diagram of people who enjoy playing TTRPGs and people who like telling scifi and fantasy stories is basically a circle.
This is also why you get people claiming Wizards get magic by being taught, sorcerers get it from bloodlines, and warlocks get it from patrons. That’s not the original meaning, that’s just DND.
This is why Druids can now turn into animals.
This is why goblins are now shorter than most other species.
Hell, a lot of modern Vampire tropes come from Vampire the Masquerade and I could go on.
It’s fine when people take inspiration from things they like. Don’t just claim that things are certain ways always without doing your homework.
