I may have heard that one. And it's a reminder of the fact that "computer" was originally a human job title. Computers were employees -- usually women -- who did the grudge work of doing calculations for scientific or engineering work. When machines were invented that could do that same job, they were called electronic computers, and once they took over the job completely from human beings, we dropped the "electronic" part.
That's how they do it in Asimov's world, the robots are so omnipresent that after a time they ceased making the distinction between men and robots.
