The main reason for this is that technology gives us the ability to find answers that others have found before us instead of coming up with answers on our own. This was always possible to some extent, but now it is much easier.
The internet is the greatest example of this. A student can now look on the internet and find all sorts of commentaries about various works of literature. They can find discussions of all sorts of topics in history. In the past, it was extremely difficult to simply look up, for example, what someone thought about the presidency of Andrew Jackson. Now, it is very easy to do so by using Google.
Because of this, some argue that we use technology to look up answers rather than thinking things through and coming up with our own answers.
