I think he's saying that "it's unlikely that Princeton will ever have 10% of its faculty dedicated to computer science". Despite the demand, universities want to remain balanced and avoid becoming trade schools.
"Ditto" means "same for UW"; Ed Lazowska is the department chair at UW.

Take a look at Matthew Reed's Confessions of a Community College Dean as well. There are other factors at work:
1. Tenured faculty can remain until they die. Almost every school still has tenured faculty from popular areas in the 70s.
2. It can be dangerous to chase trends, thanks to tenure: if the school tenures a bunch of CS professors today, and then something else comes along tomorrow, those profs can remain for 50 years.
3. Mandatory retirement ages were eliminated by the Supreme Court in the late 80s and early 90s (again, see Reed's discussion), which lends extra importance to points 1 and 2.
He was the department chair at UW when I was a CSE student in 1995 (and through when I graduated in 1998). He definitely isn't anymore (I hope!).
He does have the Bill and Melinda chair of computer science, but this is something else entirely. The current chair of the department seems to be Hank Levy.
