Probably better to ask on an alt.sociology newsgroup but the I expect
businesses were asking the same questions about the telephone a century
ago. Couple of years ago I recommended that our marketing people put
E-Mail addresses on their business cards "or else in a few years we will
not be taken seriously". E-Mail is just an easier-to-use FAX (that security
is having a problem right now is not pertinemt to the business needs and
is solvable with secure channels).
Not saying the Internet is going to replace internal networks, it has a
different function entirely that is just starting to be tapped.
When the world and I were young, vaccuum chute arrangements were a common way
of moving paper (drive in tellers at banks still use them). In the early '80s
"networks" were 3270s and VT-100s serial linked to the mainframe in the glass
room (and people looked at me strangely when I brought my cart with the
Columbia VP-1600 - 32 pounds, remember "luggables" ? - strapped to it into
the office daily and used PC-TALK to pass what I had been working on the night
before to the VAX).
Today the fact that you have a "private network" is taken for granted. In
two years so will the Internet.
