Like
the god Thoth in Plato, the inventor of the pocket calculator will undoubtedly
think that he has done humanity a great service. And I must admit that
using a pocket calculator is more efficient than browsing through a
table of logarithms, which used to be the fashion in my high-school
days. Furthermore it must be admitted that a table of logarithms hardly
fitted inside your breast pocket. However, King Thamos of Egypt is right
again when he says that such an invention stimulates ignorance. How
many people possess a pocket calculator, but havent got the slightest
notion of the calculating processes? Analogous to that, one can see
the same in business automation, where users hardly have any idea of
what the computer actually does.
Pocket calculators should in fact only be issued to people who have
sufficient notion of the plausibility of what the machine is doing.
By notion of the plausibility, we mean that when giving the entries
and the instruction, the user should have an idea of what the outcome
should be.
