One terabyte of Word documents is expected to contain 85,899,345 pages. If you can genuinely create that much stuff, you're in for a big archiving challenge. I am now reading David McCullough's book "John Adams," which is around 650 pages long. It was published in 2009. That means I'd have to write two more books like it every year for the next century just to fill up my archive. The way we store information today is not very efficient. We rely on large libraries and data centers filled with millions of books and files that take up a lot of space. An alternative approach would be to store our knowledge directly in our brains, but we're a long way from being able to do that. For now, we need ways to store information that are both accessible and affordable. The cloud is popular because of its efficiency and ease of use. There are also services available that will copy your files to multiple servers all over the world, ensuring their survival in case something happens to any of them. Word documents are the most common form of file sharing online. If you had an archive containing only these files, it would be impossible to open it unless you knew exactly where to look. The cloud solves this problem by storing multiple copies of your files in different locations that can be accessed from anywhere in the world. As long as there is internet access, you can open your document.
