the full quote:

More than anything else, the greatest danger to good computer science research today may be excessive rele- vance. Evidence for the worldwide fascination with computers is everywhere, ftom the articles on the financial, and even the front pages of the newspapers, to the difficulties that even the most prestigious universities experience in finding and keeping faculty in cornputer science. The best professors, instead of teaching bright students, join start-up companies, and often discover that their brightest students have preceded them. Computer science is in the limelight, especially those aspects, such as systems, languages, and machine architecture, that may have immediate commercial applications. The attention is flattering, but it can work to the detriment of good research.

As the intensity of research in a particular area increases, so does the impulse to keep its results secret. | ritchie's turing award lecture: reflecting on software research, cacm, vol27, 8. august 1984
