When Google automatically completes a word you're typing in its search box, that's not an algorithm adding those letters - that's a real person. A real person with the job "autocompleter." "On a good day I average about 34,000 words per minute," says one Google autocompleter, who started out as a "spellchecker." Google's April Fools ad for a new autocompleting job, says "You'll be expected to successfully guess a user's intention as he or she starts typing instantly. In a fraction of a second, you'll need to type in your prediction that will be added to the list of suggestions given by Google. Don't worry, after a few million predictions you'll grow the required reflexes."
