Obviously I can't speak for them, but as someone who has a lifelong disability (permanent hearing damage plus permanent loud tinnitus that I still hear as I type this, and even in dreams) it's infinitely more depressing for me to see by the 32nd century that these things can't be cured.
I imagine even the vets want their old life back. As a disabled person, I actually find that Detmer not having a cure in the 32nd century sends the message "Even in the far future, you're still forgotten and curing you is not a priority."
Detmer being cured sends a message to me, as a disabled person, that says "We never forgot you, we never stopped trying to undo the damage done to you that wasn't your fault, and we worked tirelessly scientifically until we found a treatment."
I can't imagine I'm the only disabled person who sees it this way. It's also a bit grating that non-disabled people (not speaking to you specifically but in general that I've seen as I don't know if you have a disability or not) presume to speak for people who actually have a disability.
