Internet has changed the way we do things, for example, if you have to do a project you can look for more information on Internet and you don't need a dictionary or an Encyclopaedia. You can also listen to music online and even download it. Internet is a way to communicate with your friends too. You can chat with them so you don’t need to phone them and you don’t spend money.
For these reasons, I think Internet will be used by all people in the future.
