Writing teaches you to think, and you can't outsource that to a bot. It's hard to see how using these tools to eliminate grunt work and generate ideas wouldn't be a good investment in preparing for our uncertain A.I. future.

"Writing is the process by which you realize that you do not understand what you are talking about. Importantly, writing is also the process by which you figure it out," writes Farnam Street blogger Shane Parrish. "Writing about something is one of the best ways to learn about it."
