【正确答案】Speech is the most convenient form of communication. In the future we want essentially natural conversations with computers. The primary point of contact will be a simple device that will act as our window on the world. It will have to be small enough to slip into your pocket, so there will be a screen but no keyboard: you will simply talk to it. The device will be permanently connected to the internet and will beep relevant information up to you as it comes in. Such devices will evolve naturally in the next five to ten years.
