People are supposed to tell computers what to do, but in practice it's been the other way round quite a long time.
As an example from the extreme end, I recall an incident that happened to my mother's coworker. (This would be more than 15 years ago now.)
One day, her bank card stopped working. Payment terminals wouldn't authorize anything. ATM's wouldn't allow to even get a cash balance. So, over the lunch she went to the local bank branch to find if there was something wrong. Went to the till, presented the card and ID and explained that all of a sudden her card wouldn't work anymore. The clerk checked from the computer, looked up and responded in a calm manner: "You are dead."
Eventually the reason was discovered too. A full namesake had died and the paperwork for terminating the accounts had gone through. The person doing the closing had done an account search based on the full name only and closed everything.
It took a few weeks to get the mess reversed, much of it spent combating the bank to even accept the existence of a clerical error. As far as I know, they never accepted the responsibility of the cock-up.
As amusing as that anecdote may be, the real problem is this: for the bank clerk, the output from the computer screen overrode the reality that was, literally, standing in front of her. Ever since then, our reliance on computers telling us what to do has only increased.
Drivers, blindly taking instructions from their satnav, will easily ignore the reality around them. We've conditioned our users to believe the computer over their own senses.
