Any person living in a technologically modern environment who is either incapable of, or eschews attempts at becoming technologically fluent and competent. A person born in the late twentieth century, who despite ready access and exposure to devices like tape recorders, CD/DVD players, cell phones, computers, etc. is unable or unwilling to use or understand them.
