Our marketing people are out there fighting against years of received wisdom. The belief that the computer species can do many things faster, cheaper, and better than the human species is socially constructed, influenced by notions of progress, strictly teleological theories of history, and the computer industry's PR machine.

Computers are pricey.
They need consultants. When a computer breaks, work grinds to a screeching halt. When a person is sick, the office goes on without that person.
