content: Same here. I believe they would make me dumber, as having access to the internet at all times would guarantee that I never really learn anything. By which I mean, there are two ways your brain stores information. It can either store the data itself, which is more difficult, or it can index it, meaning that it doesn't remember the data itself, but remembers where to find it, which is easier. It's like living your life like it was either a closed book or open book test. Closed book, you have to actually remember things. You actually have to know things. Open book, all you have to know is around what page the answers are on, and then you can forget the data again until you need to check that page again. You know nothing, but you can find it, probably. Instead of learning and storing all the information they would normally accumulate, a person instead only has to learn one index point. 'open phone use google'. TL;DR : smart phones end up being used as externalized memory, causing people to use their internal memory for nothing but index points, and being unused to actually learning things to the point of intellectual atrophy.
