Some have claimed that BSDI could not have implemented a free version of
Unix in the short period it took them:

	"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: UNIX can run on
	hardware costing as little as $40,000, and less than two man-years
	were spent on the main system software."
