In fact, even in the era without the Internet, many learned people have not read all the books. Sometimes, he also needs to search in the sea of books, but the speed is slower than the current network.
Therefore, the information obtained only through the network is incomplete to some extent. If you want to study in a certain field, you still need to read the whole book. Of course, it is not limited to the paper version or the electronic version. The essence of knowledge will not change at any time, so don't be confused by its carrier.
You can think of all kinds of information on the Internet as an index of all kinds of books. What do you need to know? Follow it.
After all, compared with the ancients, he may not get the information for a year, and now we may get it in a few minutes. Isn't this happy?
Another view is that the Internet has broadened people's wealth. Smart people know how to acquire the knowledge they need, and unintelligent people can only be drowned in junk information.
