Earlier quoted context omitted.
Don't get it (was it a joke?) Answering your question: To become a better computer scientist.
You can't call yourself a computer scientist by doing self taught education. That's the biggest problem with it
better computer scientist needs interaction with other people, needs to learn to respect their views or at least understand them, evaluate. perhaps needs to meet other scientists. to exchange ideas and approaches. this is what schools and academia is for.
this whole self-taught thing is a time-bomb. we already have too many self-taught engineers, architects and what-nots who can only work with themselves, listen to themselves, and agree to their own designs. not okay.
being good at anything more often than not means also being good in working with people.
even though you can also call yourself better piper or better kiter, doesn't mean you actually are better at anything just like this.
