I quite agree with the fact that self learning is not enough.
Another thing you learn in studying in University is the fact that you can
be wrong, which is quite difficult to accept for self taught people. When
you work in groups, you are bound to admit that you don't have the best
solution all the time. To my experience, self-taught people I worked with
had tremendous difficulties to accept that they were wrong, that their
design was badly done, that their code was badly written or strangely
Because self teaching was done with a lot of efforts, in particular to
figure out complex problems on their own. Most of the time, the self
learned people are attached to the things they learned by themselves and
have difficulties to envisage that being right of wrong is often not an
issue provided the group comes to the best option. They often live
contradiction as a personal offense while it is just work, you know.
That's another interest of the degree, confrontation with other people
that have the same background. And letting the things learned at the place
they should be and not in the affective area.
