Yes, Carol, the beginning of the twenty-first century is just as different to the end of the twentieth century as the beginning of the twentieth century was to the end of the nineteenth. Back then, cars replaced horses and changed the way people travelled. Now, technology has replaced mechanical machinery and changed the way people gather information. We are still using cars so, I guess, we will still be using electronics for exchanging information at the end of this century. Working horses are also still around and hard copies of information will still be around until the twenty-second century, but not to the extent we see today. Good news (excuse the pun!) for tree lovers!
