I'm currently reading Nick Carr's 'The Shallows'. Enjoying it so far and he makes a fairly strong argument on the neuro changes as our brains adapt.<p>I've also found it fascinating (yet obvious in hindsight) his discussion of how any technology has an impact on our intellect (it's 'intellectual ethics'). From the invention of clay tablets and papyrus to the typewriter, each has influence on the output and operations of our intellects.
