CHAPTER ONE
Cautious Cars and
Cantankerous Kitchens

How Machines Take Control

    

I'm driving my car through the winding mountain roads between my home and the Pacific Ocean. Sharp curves drop off steeply amidst the towering redwood trees and vistas of the San Francisco Bay on one side and the Pacific Ocean on the other. It's a wonderful drive, the car responding effortlessly to the challenge, negotiating sharp turns with grace. At least, that's how I am feeling. But then I notice that my wife is tense: she's scared. Her feet are braced against the floor, her shoulders hunched, her arms against the dashboard. “What's the matter?” I ask, “Calm down, I know what I'm doing.”

Now imagine another scenario. I'm driving on the same winding, mountain road, and I notice that my car is tense: it's scared. The seats straighten, the seat belts tighten, and the dashboard starts beeping at me. I notice the brakes are being applied automatically. “Oops,” I think, “I'd better slow down.”

Do you think the idea of a frightened automobile fanciful? Let me assure you, it is not. This behavior already exists on some luxury automobiles—and more is being planned. Stray out of
your lane, and some cars balk: beeping, perhaps vibrating the wheel or the seat or flashing lights in the side mirrors. Automobile companies are experimenting with partial correction, helping the driver steer the car back into its own lane. Turn signals were designed to tell other drivers that you are going to turn or switch lanes, but now they are how you tell your own car that you really do wish to turn or change lanes: “Hey, don't try to stop me,” they say to your car. “I'm doing this on purpose.”

I was once a member of a panel of consultants advising a major automobile manufacturer. I described how I would respond differently to my wife than my car. “How come?” asked fellow panelist Sherry Turkle, an MIT professor and an authority on the relationship between people and technology. “How come you listen to your car more than your wife?”

How come, indeed. Sure, I can make up rational explanations, but they will miss the point. As we start giving the objects around us more initiative, more intelligence, and more emotion and personality, we now have to worry about how we interact with our machines.

Why do I appear to pay more attention to my car than to my wife? The answer is complex, but in the end, it comes down to communication. When my wife complains, I can ask her why, then either agree with her or try to reassure her. I can also modify my driving so that she is not so disturbed by it. But I can't have a conversation with my car: all the communication is one way.

“Do you like your new car?” I asked Tom, who was driving me to the airport after a lengthy meeting. “How do you like the navigation system?”

“I love the car,” said Tom, “but I never use the navigation system. I don't like it: I like to decide what route I will take. It doesn't give me any say.”

Machines have less power than humans, so they have more authority. Contradictory? Yes, but, oh, so true. Consider who has more power in a business negotiation. If you want to make the strongest possible deal, who should you send to the bargaining table, the CEO or someone at a lower level? The answer is counterintuitive: quite often, the lower-level employee can make the better deal. Why? Because no matter how powerful the opposing arguments, the weak representative cannot close the deal. Even in the face of persuasive arguments, he or she can only say, “I'm sorry, but I can't give you an answer until I consult with my boss,” only to come back the next day and say, “I'm sorry, but I couldn't convince my boss.” A powerful negotiator, on the other hand, might be convinced and accept the offer, even if later, there was regret.

Successful negotiators understand this bargaining ploy and won't let their opponents get away with it. When I discussed this with a friend, a successful lawyer, she laughed at me. “Hey,” she said, “if the other side tried that on me, I'd call them on it. I won't let them play that game with me.” Machines do play this game on us, and we don't have any way of refusing. When the machine intervenes, we have no alternatives except to let it take over: “It's this or nothing,” they are saying, where “nothing” is not an option.
