Hesiod had his Iron Age. Traditional Indian cosmology has its Kaliyuga. In reality, of course, the Golden Age is a rhetorical tool, not a historical fact. I am not in any way seeking to denigrate Professor Orr or his ideas. Indeed, I agree with him in principle that linguistic diversity is an extraordinarily important and positive phenomenon and that continuous overcommercialization is unfortunate.
Language is quite capable of taking care of itself.
It is a fluid, dynamic, ever-changing phenomenon. Furthermore, the sound of mouse clicks need not be the death knell of the creative use of words. Technology is not the enemy of the word. The creation of the alphabet and the printing press are clearly technological innovations that have helped spur creativity and a sophisticated use of language. The hypertext link, I believe, is the next great tool of verbal expression.
