Will a computer fix a broken door? Wash out glassware? Cook 5,000 meals every lunch hour? Knock on a dorm door, when there's a 3 am party going on? Trim the hedges? Roll the AV projector out to the lecture hall that needs it? Ticket someone for parking without a permit? Wash the windows?
Or would you prefer tenured professors doing all that work, instead of teaching, or research?
Well, I think custodians fix broken doors, kitchen staff clean the dishwasher and cook meals, RAs (who are normally students as well) knock on the doors, landscapers trim the hedges, and AV techs roll out the projectors.
If that's what "administrators" means, then fair enough - but my understanding of the title "administrator" is people who organize the curriculum, schedule staff, students and classrooms, maintain the website, conduct student intake, that kind of thing. And those are the jobs that I would expect to be streamlined via computers.
