Om Malik explains that the success of smartphones are making new kinds of affordable robots (like Baxter) possible:
What is even more exciting — well, at least to me — is that the road to this robotic future is littered with billions of smartphones. The reason why we can build robots like Baxter today is because of the falling prices of sensors and other components. Before the iPhone rolled around, phones didn’t use that many chips. Apple came along and made it normal to demand gyrometers pyrometers, accelerometers, digital cameras, touch and other such sensors.
Fascinating point. This trend should allow much more than just robots; cheap processors and sensors should allow the computerization of much of our world.
