I don’t care how many times you read this opening paragraph. Study it word for word. Examine it frontwards and backwards. You won’t be able to conclusively tell whether it was written by a human or machine.
Don’t believe me? Read this sports story, and tell me if it was written by a human or machine:
Tuesday was a great day for W. Roberts, as the junior pitcher threw a perfect game to carry Virginia to a 2-0 victory over George Washington at Davenport Field.
Human or machine? Here’s the answer: It was written by a machine. (I wrote the opening paragraph.)
See, when it comes to a computer-generated story, there aren’t any telltale signs that it’s manufactured by a machine. That’s how good this machine-written content is getting.
