Welcome to the Big Blur

The question will be simple but perpetual: Person or machine? Every encounter with language, other than in the flesh, will now bring with it that small, consuming test. For some--teachers, professors, journalists--the question of humanity will be urgent and essential. For those who operate in the large bureaucratic apparatus of boilerplate--copywriters, lawyers, advertisers, political strategists--the question will be irrelevant except as a matter of efficiency. How will they use new artificial-intelligence technology to accelerate the production of language that was already mostly automatic? For everyone, the question will now hover, quotidian and cosmic, over words wherever you find them: Who's there?
