Would you prefer supervision, supersmell, superfeel, superhearing, or supertaste? And what about the other senses of the body that are not part of the quintet? Think balance, temperature, and even the ability to feel where all your body parts are (you can close your eyes, wave your hands around, and touch your knee)
For me, I would pick supervision. It would be really cool to see better in the dark, have built-in camera zoom, and see in higher detail.
I would argue that instead of wishing for impairment to cope with the overstimulation, you just wish for the part of your brain that handles sensory input to be able to handle your normal sensory load without issue.
Oh, nice thought. A dedicated sensory co-brain.
