My grandparents' phone number was 1331. Those four digits were all you needed to reach them. If you called from further away, there was also the area code 04454.
In
those days you knew the numbers of family and friends by heart. Other numbers were
kept in a special telephone directory: you set a slider to the first letter of
the surname, pressed a button and the thing popped open and showed a card with
all the names and numbers that belonged to that letter. Handwritten.
At
home we didn't have a telephone at all for a long time. You could live with
that in the seventies. And the one time you really had to call someone, you
knocked on the neighbours' door and gave them a quarter (of the old Dutch
currency, the guilder). Or you went to the telephone box in the village. You
needed quarters there too. Those were important coins. Too bad they don't exist
anymore.
When
we finally got a phone, four digits were still enough. Ours were 4006. PTT was
the monopolist and everyone had the same device: the T65, with a rotary dial
and a curly cord. It sat in the living room and if you were busy in the
kitchen, with the door closed, you would sometimes miss a call. And you only
knew that when the caller tried again later ("Weren’t you at home?").
That's why my parents had that same PTT install an extra bell in the hall. You
paid rent for that, just like for the T65.
Many
years later I bought – hesitantly – my first mobile phone. A Panasonic, with an
antenna that stuck out about two centimeters above the device. The device had a
small LCD display and physical keys. You could call and text with it. Compared
to the T65, the number of functions was doubled. Wow!
Look
where we are now. Almost everyone walks around all day with a computer in their
pocket, which you also happen to be able to make phone calls with. This can be
done in various ways. Via your SIM card (the old-fashioned way of calling, with
a phone number of ten digits nowadays), but also – with or without live video –
via other apps. You can even use it to hold meetings, as we know since the covid
pandemic – if necessary with people in all corners of the world. Most people
have thrown their landline out the door. Or never had one.
But
what if all of that suddenly stops working? No one is reachable anymore, at
least not by phone. You can only communicate with each other indirectly. By
email or via chat apps. What impact would that have on our social and
professional existence? Many subjects benefit from live interaction; if they
have to be done via email, the 'conversation' can easily go the wrong way
because one person misunderstands the other.
If
telephony and video conferencing were to fail for a long time, we would
undoubtedly go back to the office more often. Then it would be like it used to
be: working from home for a maximum of one day. Everyone has their own personal
preference, but I cherish working from home. One day a week in the pandemonium (and,
admittedly, also joining in the chatter) is enough for me.
What
do we do to prevent a company-wide blackout? Diversity plays a key role. In the
Netherlands, there are three mobile networks (Vodafone, Odido (elsewhere still
known as T Mobile) and KPN (the heir to PTT!)). All other providers piggyback
on these networks. It is financially and from a management perspective
attractive for organizations to place their telephony with one provider. But if
something goes seriously wrong there, the entire organization immediately has a
blackout. So it would be better to spread your chances. You should even make
sure that the employees of a team are not all with the same provider. I see a
nice administrative challenge…
But
is it worth it? We never have long-term failures, do we? In the current
climate, I no longer dare blindly assume that it will remain that way. There
are strange forces at work in the world. At some point, those forces could
benefit from a country becoming paralyzed. We would rather not think about
that. And that is precisely why we have to do it.
And in the big bad world…
