Borg have hivemind-enforcing nanites, though. Without that you're just a regular cyborg, like Robert Cop.
How many regular cyborgs are there in Star Trek though?
Fucking Geordi needs a goofy ass attachment linked with an interface when the whole multi-spectral vision thing should just be what you get after replacing your eyes with Eyes that look exactly the same as you want them to look but which you can Open to view other wavelengths and overlays and so forth.
Hell, we know they can replace parts really well because they've deborged people, but for some reason none of the post-borg folks seem to ever say "hey, can you just leave that awesome eye implant and my multi-tool hand socket in place along with the force field generator?" because... apparently it's better to be as not!God made you? Human and flawed and weak and fragile and dying slowly.
Actually I wonder something else, why does Geordi ever need a tricorder? Same with Data, what kinda shitty android is he that he is still limited to slow ass reaction speeds like human defaults, can only manage a few Tflops, and has PB of storage? Oh but hey, he can bend a bard of tritanium or some shit, wow!
I get that they were trying to make a show with broader appeal and so forth and the Culture was just in the early formative period as a setting but I was never so disgusted and horrified at presentations of the future as I am after reading the expansive tapestries of possibility guys like Banks and Baxter put forward.
We've got weird ass gadgets like this being put out there nowadays:
