Thoughts on Library 2.0 and Web 2.0 and the future of libraries

I read three of the articles: "Into the new world of librarianship" and "To more powerful ways to cooperate", talks about the relationships of libraries with people as a place for emotional and engaging center of learning in which I agree highly with; there is a connection to people and the community. I also, like the way the articles spoke to libraries who engage in library 2.0 as adding value to better serve the public. Unfortunately, in the article "A temporary place in time", the libraries have become digital and the idea that libraries are a part of a community is no so anymore. This is because the libraries are becoming a digital downloads for people. Some people don't read anymore rather they listen to their books on CDs or download a book to an ipod. As the technology advances Library 3.0 is more like a web 3D and sooner or later Library 4.0 will be a library of meditation and relaxation, does this mean librarians don't have to deal with rude customers or that we won't have jobs anymore????
