This is an interesting topic that I really want to talk about. The reason why I am curious about predicting the future is because of the development of AI. We always talk about industrial revolution, from Watt who invented the first steam engine to the rise of information era, some new things always appeared all of a sudden which made us scared of the future. Many years ago, when the Nokia 3310 was released, we thought that the world would be controlled by Nokia forever, because their products led us into a new era which was full of advanced technology and convenience. But when their market share dropped from 70% to 3%, we were forced to use smart phones while forgetting how excited we felt when we got a new Nokia phone. We began to wonder what would be invented to replace smart phones in the future. AI appeared from nowhere, but it has been changing the world quickly. We have got used to accept new things and try our best to learn about it. We just want to know what will replace AI in the future.
