Consider email, voice-mail, and fax. I do more correspondence in one day with email than I used to do in a month with paper. When voice- mail first came in, I was outraged. I wanted my secretary personally to talk to my callers. Within a few months I reversed myself and told her to stop answering my phone.
Fax is another example.
These are order of magnitude effects. Now comes the internet - not only email but world wide web, mosaic, netscape, ftp, telnet, and still other products yet to be conceived. Like many others, I am stunned with what lives just behind my computer screen, at the beck and call of my keyboard and trackball. I pull up a full color picture of the Sydney Opera House from the home page of the Australian Graduate School of Management. Moving on, I find colleagues' faces and papers popping up at many spots around the world.
