The positive effects of this attention is that the internet has an unlimited amount of information and its all there for us to read or listen to. Any subject that you want to observe info about is going to be on the internet at our disposal. That is the positive thing about technology and its attention, we as humans know its there for us and when we want it, we go for it.
However, the negative side of all this, is probably the fact that we don’t have the time or basically don’t want look at all of it. Similiar to reading books, once you have intake a certain amount of information, your mind starts to wander. Same goes for the internet. there might be a vast amount of information for us to read, but we certainly don’t want to read all of it especially at once. For example, if I had 10 web pages open, the odds of me reading all of them are pretty slim. In this case I would choose to read the one that looks most intriguing. So it often does split our attention, to the point where we choose to read what we think will keep our attention the most. This also relates to television as well, all the channels available, but we don’t watch them all even though they there for us. We just watch what grabs our attention.
