I think I’d start with augmentations that allowed my body to realize it’s full potential as designed - first, start with efficiency and longevity gains of major organs and then maybe dig deeper to gain control over my internal operating system to unlock enhancements such as pain center management, improved hearing and vision, faster reflexes, and maybe memory management augmentations. I’d also invest in organ replacements that solve some of my current medical problems. I’d probably start here, actually.

Once the full potential of my augmented standard human frame has been reached, then I’d explore more full limb or systemic replacements to become more than human (cyber legs, internal weapons/tools), and possibly explore any bodily self-expression modifications.

I think the speed of my adoption would depend on whether this tech were available as implants or nanotech, and what the potential for cyberpsychosis impact would be.
