I don't think we're an elite, upper class now either. We're decently paid clerks that perform an essential task for our scheming, private jet flying, yes, thuggish overlords that for now at least haven't become computer literate themselves. Yet.
But the day will come that they will have, or at least will have become computer literate enough to operate the software that has displaced us.
If that day comes after I've died, I don't mind. Otherwise it'll be a problem.
For example, average programmer salary in 2004 was about £31k and in £38k http://www.itjobswatch.co.uk/jobs/uk/programmer.do and if you calculate £31k in today's money you get £38,440 [http://www.thisismoney.co.uk/money/bills/article-1633409/His...]
Since I never pass up a chance for the joke: A lawyer or accountant with 30 years of experience is charging a lot of money or semi-retired... A programmer with 30 years of experience is likely unemployed.

Related to scribes, even if mostly everyone knows how to read or write, that doesn't mean that book authors are obsolete. Writing novels and technical books is an endeavor that requires much more than simply being capable to read and write.
So I don't really get why this analogy is being made. Well, actually I do. It's for the same reason why recruiters are doing keyword matching on resumes.
