I believe it is true that computers save us a lot of space and time. If you have a good modern computer with the Internet connection, it can replace a huge library with millions of books.

They also allow us to analyze massive amounts of data very quickly, saving both our time and money.
Computers can be a great learning tool. For example, I regularly watch educational videos on the YouTube.
On the other hand, I understand those people who worry that we rely on computers too much and this habit can lead to problems with social interaction. That is why it is important to find middle ground between two extremes.
