Future of libraries

I've read a few perspectives on web 2.0, Library 2.0 and the future of Libraries and my thoughts are that computers are taking over and we need to be ready for changes to libraries.I think that having self serve computers for Patrons to borrow is a great idea as its quicker for them [No waiting].But you cant rely on computers 100% as sometimes they play up.Then thats when you need us staff who you can rely on.Some of our patrons come into the library for some company and a little chat but with computers taking over it makes it harder to give 100% customer service.So I think there is good and bad things about were we are heading.
