Abstract

Senses evolved to when the world was wild, enabling our ancestors to detect subtle passing opportunities and dangers. Senses are less useful in a tamer world, where our interactions become more and more simple information exchanges. Senses, and the instincts using them, are increasingly liabilities, demanding entertainment rather than providing useful services. The anachronism will become more apparent as virtual realities, prosthetic sense organs and brain to computer interfaces become common. Imagine reading a computer screen if your eyes and visual cortex are artificial prostheses. It would be far better to bypass all the sensory processing, and insert the message from the computer directly into the thinking portions of your brain. In such manner all our senses will become obsolete, as our physical environment is inexorably refined from a rough physical place into a densely interconnected cyberspace.
