Just face it, you're getting too old for slashdot :) About half the people arguing with you are just trying to justify all the money they spent or are spending on education. Yes, you need calculus in academic disciplines, including computer science. You also need it in highly technical or scientific fields, like rocketry, engineering, image processing, etc. Of course, learning computer science does not necessarily teach anyone how to make good software, and in some cases an inverse correlation may be observed.
I think it's really sad how our society basically devalues skilled labour. That's what writing good software is, after all. The attitude of businesses seems to be that people are more or less replaceable and therefore expendable, and people have responded by outrageously increasing their qualifications. This costs society a lot of money in wasted time, lost productivity, lost income, and stunted career progression. The quality of education has also deteriorated under the extremely high demand. This is inflation in education: the amount of it goes up as its value drops.
It does not make sense for most software developers to have a four year computer science degree. It's hard to see what they could need beyond a solid understanding of algorithms and data structures, and exposure to different programming languages. You could learn it in two years, but it would be quite hard. Or you could learn the basics in one year and do a year of apprenticeship and two years as a journeyman to get it all. But it doesn't work that way anymore, because a great many businesses refuse to bear the costs of educating their employees. It's stupid short-term thinking, and they pay for it in other ways, but all of the career risk has been pushed onto the labour force.
So what are you missing? The value of an education is really what you make of it. I guess the best way to explain it is with an analogy. If you were to get an English degree you would study Shakespeare. It may or may not help you write a good play. If you were talented, you might pick up something from Shakespeare. Or you could study Shakespeare with great dedication, and practice writing until your work really compares. Or you could bullshit, plagiarize, and plead your way though a degree and go on to write travesty after travesty to be inflicted on an unsuspecting public. In any case, someone with a BA in English had better know Shakespeare. That's just expected, because it's part of a body of knowledge. It may or may not be related to the skills that employers are looking for.
Universities exist to maintain and expand bodies of knowledge. That's it. To the extent that they have been used as a "shortcut" for employee training or certification, it is highly unfortunate and detrimental to society as a whole. I wouldn't deny the right of an education to anyone, but society has misconstrued its purpose.
