Is Google making us dumber?

Google is so effective in retrieving information that our brains are telling us this information is not needed. Therefore, we're forgetting things like unit conversion, basic calculus, addresses and phone numbers. This might be an evolutionary step towards forgetting what's irrelevant and focusing on what's important; or maybe Google is just making us dumber."
