Ofcourse the whole world is changing and young kids will be our saviour in the future, if most of all the GEN X gone. Millennials will rule the world of crypto/digital. Remember the Dot.com bubble? When GEN X was totally disagree on the system and now they're adopting it.
We can go "semi-digital" with crypto. We can definitely digitalize many things thanks to crypto, finance being the most important one but with blockchain many things can digitalize however in the end there will always be pen and paper people.
For example kindle has brought the world of books into digital world and there are millions of people who read book on their kindle and tablets and buy ebooks instead of real books (which real saves a lot of papers and space on bookshelves if you think about it) but do not we still have regular books? We still have regular books. Crypto will make our world "semi-digital" at the same logic.
