Long before Steve Jobs or Bill Gates were even twinkles in their fathers’ eyes, the word computer was a job title for someone who computes or performs mathematical calculations. Depending which online resource you trust most, its use dates back to the 1600’s. Not until much later, sometime in the 1800’s, did it come to refer to a device rather than a human. From what I can gather, the word calculator underwent a similar evolution.
I’ve taken you on this little jaunt back in time in part because I’m under the influence of a book that I’m currently reading, Etymologicon, but mostly to make the point that another title – “data scientist” – is likely to follow the same trajectory.
