Carr on Memory and Self

Nick Carr excerpts a chapter of his book: The Shallows, on the concept of aiding memory.  Is memory being killed by all our digital memory aids and resources?   " ...  I looked into what we know (and don't know) about human memory and its role in our thinking and the development of our sense of self.... " .    I agree that the search memory model we have taken from our recent involvement with computers is wrong, but there are other models that are much more brain like, like associative memory, which we are just starting to examine.  Take a look, for example at developments by companies like Saffron Technologies.  Not to say the problem is solved, but there are other approaches.  Does this ultimately hurt a person's sense of self?  No more than having a big library does.  It does make recall much more efficient.
