Leaving aside the snobbery and "not invented here" syndrome, I suggest that Mr Boyd educate himself by reading some collections from Ted Chiang, Ursula Le Guin (who even many outside the field recognize as a truly outstanding writer), Gene Wolfe, and Harlan Ellison (and I'd say that even if he wasn't my client). He might find some pleasant surprises; but, in the best of all possible worlds, these would not be surprises, because he would not have prejudged the books by the rocket ships on the covers. (Well, none of these actually have a rocket ship, but still…)
Of course, this is not the best of all possible worlds.
