I don't think this is a fair criticism of the text. However good Unix might have been in the 1970s, why am I still running it on my mobile phone? How good is it today? It seems that the major argument in its favor is legacy. (Honestly, it seems to me that most of his criticisms could be moved away from stepwise. I'm guessing most of the configuration on my phone is stored in binary files. Someone could write the object-wise commandline utils he wants, and then create the architecture to make them more efficient. We could move there. Should we?)
