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.
There are many dimensions to each of our senses. Just taking super-vision as an example, would that involve seeing very small things, seeing things at great distances, seeing through things or around corners, seeing more colors and/or wavelengths of light, seeing in 360°, seeing more subtle things than others see (like being able to see when someone’s heart rate increases), processing what you see quicker (for quicker reactions), photographic memory, seeing things others can’t (like magnetic fields or temperature), greater “frame rate”, seeing in the dark, a HUD with information display, seeing ghosts, or something else entirely I haven’t even thought of?
