Are books obsolete?

Hard copy and softcover books will never be obsolete. 

Never.......there will always be those  who enjoy holding a good solid book and flipping the pages, than reading off some device giving you eye strain. 

Books are never obsolete. Why should books be obsolete?

Books don't need batteries, so no, they are the base for information.

I bought a book a couple of days ago. I do some of my learning from online courses now like EDX but these courses are prepared using books in the first place . Some travel blogs get turned into books and YouTube hosts audiobooks. The lines between books and blogs and podcasts might blur until books get renamed. Do you consider Wikipedia to be a book? What about Dicken's novels which originally appeared in newspapers?

Absolutely not. Though more and more people read ebooks instead of the printed books, it's only a change of the medium.

no they're not, since they hold a legacy. 

Seeing there are still billions of books around, and more books being published every year, it's obvious that books aren't "obsolete".

Whether they'll become so in the future is a separate question.

As long as there are languages, there will be books.

no they are not.
