I don't think so. printed books won't be abandoned in such a short time. I admit that new technology is developing fast.
Many advanced electronic products are gradually take the place of traditional tools. Just like in university, teachers like to use multimedia in class for it is quite convenient and efficient. However, for our student, it is not realistic to study completely by electronic products.
There are many things need to recorded on books. Books are something meaningful and practical. I should say, in our country, printed books wouldn't be abandoned within 20 years at least for two reasons.
Firstly, books are classical container of knowledge. They accompany human to advance. A student without books could be someway ridiculous.
Secondly, our country haven't developed so strong to make every student study by computer or other forms of electronic tools. And even after 20 years, the possibility is also very small.
I also think it is unnecessary because books are cheap but useful and still meaningful.
