If you try to predict the future of technology, you'll probably get it horribly wrong - like the prediction made by T.J. Watson, the head of IBM, in 1943: "I think there may be a world market for five computers in total." Soon, in rich countries, there will be more computers than people.
However, Kazuo Kashio, the president of Casio, is particularly good at predicting the future. "I can tell immediately which gadgets will sell well and which gadgets won't."
So what will be the best-selling gadgets ten years from now? Surprisingly, Kazuo believes that watches may be the future - watches with different functions. For example, they could be mobile phones, MP3 players and computers as well. "It will be the ultimate mobile gadget that you can't drop." Judging by his success in the past, he might be right!
