Thought for the (last) decade?

Just found a wonderful quote from the original, July 1974, Communications of the ACM paper on UNIX written by DMR and Ken. They say:

"Perhaps the most important achievement of UNIX is to demonstrate that a powerful operating system for interactive use need not be expensive either in equipment or in human effort"

This is perhaps something that SCO should have considered over a decade ago when they first decided to pursue Linux because (they felt) it was created far too quickly to have been done without stealing (what they believed was their) UNIX IP.
