Well, that's exactly how cyberware works in the Cyberpunk 2020 universe: the more Cyberware you have, the less you are able to think as other humans and to understand them, making you socially awkward to other humans.
You may find it illogical, but that's just how it works, just the same as any other kind of sci-fi magic from that universe.
I'm just not feeling or believing in these limitations or rules. I have no reason to, and no ideas why I should think that it works that way, no emotional investment, nothing. In order for a game or its lore to sell me an idea and a feeling of magic, it must be convincing. Currently, I am completely not convinced of the idea of Cyberpsychosis at all, and just saying "it just works this way" isn't really any more reason for me to accept that. If someone can provide a really really good argument with solid evidence as to why I could or should actually begin to believe that cyberware somehow makes someone less social, and then eventually go full cyberpsychosis, just like that, then maybe I would think about it and consider it.
But so far, I have never, not once heard a single reason why someone having a robot arm (CONSENSUALLY) should automatically begin to have cyberpsychosis. I could fully understand if cyberpsychosis happened to someone was was modified against their will and consent, 100% fully understand, but for someone who willingly chose to, and were happy to be modified or modify themselves, I can not accept that they will just magically automatically being to have cyberpsychosis.
It's just like someone walks up to me and says if I eat a potato that I will get potatopsychosis, and I ask them "okay why?" and they wont tell me why, and I just know it's fake. I am beyond the level of disbelief, and currently as a result of the lack of evidence am not unwilling, but actually incapable to hanging on to even a tiny shred of respect for the fully unsupported idea, no matter how hard I try to entertain it as a concept. I am willing to be convinced, but so far I have never heard a good argument that supports it, let alone even proves that it's even real in the first place.
All I see it as, is a very easy excuse to not let me modify my character to the extent that I actually wish to modify them to, under the false pretense that they are guaranteed to lose their minds for no reason, when clearly, other characters are completely fine and have full body conversions.
If anything, I think it's highly possible that Cyberpsychosis is actually a fake made up concept WITHIN the game lore, used by Mega-Corporations as a conspiracy to silence and do away with people they want to get rid of. THAT would be extremely fascinating because there is more evidence to support that Cyberpsychosis is clearly fake, and there are clear motives as to why the definition would be created by important figures (I mean NPCS inside Cyberpunk2077) Basically the bad guys say "Hey! That person has cyberpsychosis!" and basically get rid of anyone they want.
(Basically a conspiracy theory inside of the game that the enemies use to just make good guys disappear. This very well fits the Cyberpunk2077 theme and lore too, because well, conspiracy theories. KEEP IN MIND, I AM NOT TALKING ABOUT CDPR! I'M TALKING ABOUT INSIDE THE GAME just in case I'm misunderstood )
That's what I think, Honest opinion.
