Which of the following are achievable feats of bio-engineering -
The first option is difficult because vision takes place through the visual cortex, which can process frequencies in the visible spectrum, and x-ray interpretation is not possible. i.e. first we will have to introduce x-ray receptors for rods and cones and then hardwire the brain to interpret these.
The second option seems likely for example, introduce genes from the firefly into the human genome to create a cyborg hybrid.
The third option is difficult because nanotechnology will have to create a hybrid (intelligent tactile) material that responds to stimuli like normal human skin does.
What does the future hold ?
