It's not that a CS program has no useful content, but that the content is available to anyone interested in finding it. Knuth is accessible to a mathematically-inclined person with a tenth grade (equivalent) knowledge of mathematics (and three hundred bucks in his pocket), SICP is eerily transparent, the Dragon Book is certainly not beyond the ken of mere mortals, and so it goes. Admittedly, it takes more work to move beyond naivete without a formal education, but those who care about the craft will eventually get there. Those who do not care will still bubble sort despite their degree.
