Tom and Charlie are talking about the future.
"What's our world going to be like in the future?" asks Tom.
"Well, no one knows, but it's interesting to guess."
"In the future, everyone is going to carry a pocket computer. The computers can help people do all kinds of things. We are going to have very small telephones in our pockets too. Then people are going to talk to their friends all over the world. Maybe we are going to live and work under the sea. People might build towns, factories and farms under the sea too.
"Machines are going to do most of the work, and so people are going to have more holidays. They are going to the moon and have their holidays there."
