If you like science fiction at all, give Accelerando a read. Of course it's just a story, but it feels like a possible real future (at least the first section). In it, there is definitely a place for people who reject integrating with technology, but that place is in the back and left behind. Instant access to all of digital knowledge, unlimited storage for every thought or experience that interests you, performing complicated calculations, visualizing higher dimensions, and so on. Your fingers, ears, and voice aren't that quick, and your eyes are limited to 2D and only have decent resolution around the center. There is certainly room for improvement over what evolved in mammals (or any animal).

It probably won't be real before I die of old age, and I'd certainly let the early adopters find the bugs, but sign me up for version 3.0 or later if I'm still around.
