The whole premise of checking for human writing is daft

I understand why people want you to write; because it’s good for you, because it focuses a wandering thought, because the first sentence is usually rubbish and the seventh is often better, because you learn cadence and structure and argument through repetition, because there are things you don’t know you believe until you try to explain them, and because spending an afternoon wrestling a stubborn idea into words can leave you with a stronger brain; but none of this explains why we’ve decided that the physical production of every word, one keystroke at a time, must now serve as a test of whether a thought is human.
