Is Google Making Us Stupid ?
Maps of World put together this extensive look at all that Google does and all that we use it for. They look at the point made by Nicholas Carr in 2008 that Google was making users slow learners. The notion that those who are running the commercial Internet do not want the user to take a slow,deliberate approach to what they are reading and searching.
I would say no, I think the quick access to facts and figures makes us smarter. I think it depends on each user's ability to retain facts or memorize them.
