The point, it seems to me, isn’t whether the Internet is “good” or “bad” for our brains. The Internet has changed us, just as the printed book and the typewriter did. The Internet sharpens us and makes us faster thinkers, more adept at shifting between tasks, even as it erodes our ability to focus on a single topic, a single work, for long periods of time. The point is that whether you think the Internet is “good for your mind”, or exactly the opposite, depends on your values.
