Nah, it's not: your attitude towards people with a degree in computer
science agrees with what I wrote.

I disagree.

Oh, that's what I was not implying. I am convinced that quite some
people who do self-study can end up with better understanding of things
than people who do it for a degree. I have done both: I already was
programming in several languages before I was studying CS. And my
experience is that a formal study in CS can't compare to home study
unless you're really good and have the time and drive to read formal
books written on CS. And my experience is that most self-educaters don't
have that time.

On the other hand: some people I knew during my studies had no problem
at all with introducing countless memory leaks in small programs (and
turning off compiler warnings, because it gave so much noise...)

Yes, yes, and Albert Einstein worked at an office.

Those people are very rare. 

But my experience (see for plenty of examples: Slashdot) is that quite
some people who don't have a degree think that all that formal education
is just some paper pushing and doesn't count. While some of those who do
have the paper think they know it all. Those people who are right in
either group are a minority in my experience.

As for electrical engineering: done that (BSc) and one of my class mates
managed to connect a transformer the wrong way around.... twice. Yet he
had the highest mark in our class.

So in short: yes, self-study can make you good at something. But
self-study IMO is not in general a replacement for a degree. Someone who
can become great after self-study would excel at a formal study and
learn more. Study works best if there is competition and if there are
challenges. I still study a lot at home, but I do miss the challenges
and competition.
