Picture yourself in the captain's chair. You have a crew of officers who never tire, know a little, or a lot, about everything, and answer the instant you ask. Not one Data — several. They can do all the work for you. Splendid.
But they share one flaw. They'll answer with the same calm confidence whether they're right or wrong; they have no memory of what being wrong costs; they don't care about the consequence. "I calculate that you have a 67% chance of survival." (Note: there is no "we" on this ship!)
And sooner or later someone — an examination marker, a supervisor, a conference room — will ask how you got to the conclusions of your work. "The AI said so" is not a strong answer. In fact, it's a lot worse than "I have absolutely no clue." A captain who can't evaluate a response to an order should never have given the order.
The job was never to have the crew that can do all the work for you — everyone has a crew like this now. The job is to command it: to know what to ask, what to check, what to own, and what to do with the output. And to keep the log, so you can show your work when you're asked — what you requested, what you checked, what you decided.
