That's the ultimate projection of "Weak" cyborging, just a more advanced version of the optical aids I've had to wear since I was a child in order to have normal visual acuity. And frankly, the idea of taking the first step past that to "Strong" cyborging (the same thing, but wired to my optic nerve instead) doesn't bother me much. Nor does the idea of having a direct link of some sort to do math problems for me (just removing all the clunky limitations of a calculator).
In fact, I don't start getting uncomfortable about the idea of cyborging myself until we're talking about storing "memory" in there. Having a perfect recall of every line of code I've ever seen would be handy, but do I want to save a text conversion (or even full audio/video) of every conversation I ever had? Actually, probably I would, if I could, although I'd feel cautious at first.
I *want* to be a cyborg, in truth. My only bitch about the coming man-machine interfaces is that it's unlikely they'll find a way to turn my physical body into a disposable peripheral before it wears out on me. Why not? How is it any less natural to store a memory of what I see in silicon that I keep internally than to keep it on videotape? Give me a perfect memory, the ability to solve any mathematical problem I can define "in my head", the ability to "see" everything around me, or even tele-project my perceptions. I'll take all of it, and love it.
When will I cross the line from being a human using artificial aid to being a machine with biological components? Ask me in about 30 years. Maybe I'll still consider the question worth answering
