Omega puts it very well. Now here's my contribution.
Speaking as someone who has multiple disabilities, one of which would be fatal if not for modern medicine, disabilities are... complicated. Many disabilities, like that fatal one I have, are invisible and you wouldn't know I had it unless you read my medical history.
Ableism is a very complicated issue. The SJWs, as they are wont, do nothing to actually fix it and just make things worse while profiting off human suffering. What makes things difficult is that there are numerous disabilities, and disabled and able-bodied people have different frames of reference that makes it difficult to understand each other.
If there was a cure for my disabilities, then I would take it in a heartbeat. Not just so that I can survive without medical assistance, but just to fit in with the majority and not feel like a freak. (And the entire time I would secretly resent them for not liking the real me.) Other people with disabilities feel completely different.
And other times there is the
Ashley Treatment. Parents sterilized their effectively braindead child, meaning that when (not if) she is sexually abused by a future caregiver, nobody will be the wiser. The only reason I would ever advocate curing disabled people against their will would be to protect them from that kind of abuse, or at least let them get bloody revenge on their abusers.
Don't even get me started on disabled superheroes. Most of the time they're effectively cured of their disability (e.g. a girl in a wheelchair bonding to a symbiote that can walk for her, professor X riding a hovercraft) or have other senses trivially compensate (e.g. blind superheroes with perfect echolocation, deaf superheroes with vibration sense that can perfectly understand speech without looking at someone or listen to music, etc).
Representation typically isn't done for the sake of disabled people (the exception being when disabled actors et al are employed for the production, so they're financially benefitting) but for white knights to virtue signal how progressive they are. The irony is that often disabled people can't even appreciate the full scope of the production anyway because it is ultimately made by and for those who aren't disabled. Media made by and for the disabled is... well, Hollywood obviously isn't investing in it with things like silent movies for the deaf, audio dramas for the blind, or acting intended to be enjoyed by the socially blind, so we know Hollywood doesn't really give a flying fuck.
And this is just going to get worse once we do develop practical "cures" for people lacking particular senses, because this will interact in weird ways with giving
new senses to able-bodied people. Humans can't normally see ultraviolet light, but a bionic implant might give you the ability to. Wouldn't a person with ultraviolet vision be considered more able-bodied than other people? What about effective telepathy via internal radio transceiver? Able-bodied people would be effectively deaf compared to radio-talkers. Artists with these new senses will naturally produce art that only people with those senses can fully appreciate. Ultrasonic symphonies, ultraviolet paintings, whatever only people whose primarily sensory modalities are sonar and electroreception would appreciate. Companies will discriminate against disabled applicants who refuse to get implants unless they're legally forced not to. You won't even be allowed to retire anymore if you can afford life extension treatments and there aren't enough young workers to replace you due to our projected falling population.
The SJW-made cyberpunk games completely miss this. They demonize bioconservatives (i.e. people who are severely socially/medically disabled in such a setting) while treating disability as a fashion accessory.
If we can't sort this shit out now, then we're screwed once our current cyberpunk dystopia actually develops the "cyber" part to match our fiction.
So whoever wrote that book can kindly go to hell.
