Computers are used by non-IT people. While I like the idea of people
understanding computer stuff and it is possible to teach them some
basics they will never master the fine details of what is going on.

1) First, it is unnecessary: Interaction designers can invent smooth
user interfaces quite easily. An extra polish is difficult but current
state of affairs will much benefit from usability basics. In my
experience programmers do not know how to remove the obstacle their
users are experiencing (or even what the obstacle is) and fall-back to
position of educating the users. Even when the particular case is easy
for a UI hobbyist like me.

2) Second, it hampers development. If people know how things work they
resist changing the internal workings - in order to avoid having to
learn the new stuff. Programmers try to not change program's interface
even if makes their work harder and the result is suboptimal
(code-wise and ergonomically) - because otherwise their users would
have to be re-taught, will make mistakes in meantime and will whine.

Imagine if people are required to set their IP address (manually):
their computer will not work in when they roam to other network; their
computer will also make ugly stuff on the foreign network and make
some other computer nonoperational (we still lack Duplicate IPv4
Address Detection AFAIK). If the user just knew about IP addresses: it
will be more difficult to move to IPv6. Programmer just opening TCP
connection using Berkeley sockets has to adjust his code to work with
IPv6 although the difference is not important to the code.

3) Third, it limits scaling. If employee does not have to know how to
use a program then many employees can use the program. Similarly if
program component/class does not expose its internals it can fulfill
its contract on other machine or with different algorithm or using
different data structure if programmer seems it fit.

4) Fourth: it is not practical to try fix people while we can fix the
code. Many people's issues on #ubuntu IRC channel, forums etc can be
avoided by clearer error messages, by built-in diagnostics, sanity
checking user input, distinguishing between input from user and
machine etc. Millions of people constantly forgetting and
misinterpreting versus code at hand.

5) Fifth: it is selfish / not ethical for us to consider our field of
expertise more important or enough that others should even bother
about the field. People already know much about botanics, physics,
chemistry or their work/hobby. I want other people's life to be
happier and they seem pretty happy without knowing the internals.
Though, if person expresses an interest I will be happy to teach.

These sound like arguments _for_ "intuitive". (A person begins by
somehow knowing he needs a bittorent-thing. The thing evokes feelings
of application or program with a sense of internet or document related
group.)

One can be taught an alphabet but the alphabet (the ordering) is not
intuitive. In our case we can remove the need to know the "alphabet".

Summary:
I would be great if people knew more/everything about computers,
certainly it would solve many of our problems but it is not practical.
I am afraid we will never get anything better than intuition.

It might be useful for marketing, though. I have heard that sales
people pick product's property at random, make it great or look great
and (lay) people buy it. It might work for us, too.

I am sorry if am over-reacting but...
