A cyborg, defined as a self-regulating integration of artificial and natural systems, involves the enhancement of human physiological processes through mechanical devices. The document discusses various advancements in brain-computer interfaces, highlighting experiments conducted by Professor Kevin Warwick, who became the first cyborg through implanted technology that allows him to control devices with his thoughts. While cyborg technology presents significant benefits, such as restoring lost functions and enhancing capabilities, it also raises concerns about security, maintenance costs, and ethical implications.
