"Price's law states that the square root of the number of people in a domain do 50% of the work. This means the number of "useful" people increases linearly with size but the number of not-so-useful people increases exponentially. If you have 10 people, 3 do half the work. If you have 100 people, 10 do half the work. Google has 60k employees, so about 250 people are getting half the work done. This is basically impossible to maintain and is part of the reason megacorps die."
