Actually, Zuck made a statement exactly like that last fall. He basically described his model of running a company as just another engineering problem, comparing delegating tasks to writing subroutines.

I've found the video of him saying that at StartupSchool

Seek at 9:30.

Ah, interesting. I was actually referring to this talk he gave here at CMU -- http://www.ustream.tv/recorded/18392445 -- but he says the same thing almost word for word (spent ~15 minutes trying to find where he says it; I couldn't find it, but I remember him saying it).

Well, they are probabilistic machines then! ;-)
