Tools that change the way we think

I think the use of technology changes the way people think very much. I mean when i do research papers rarely do i go out to a library (do those even exist anymore) i just fine multiple online resources and use all of those. I think it can both help people get something done. But also slow them down alot. I mean like right now im on tumblr and its taken 15 minutes to type this much  :o
