its the next abstraction of search. A search does not answer a question correctly necessarily. Its pretty much not going to stop the same as having people not search online and instead go through newspapers and encylopedias and refernce texts. Energy wise if they are entertaining themselved and not generating images and just screwing around with text then its preferable to streaming vidoe if replacing it. The scariest part is it being used ineffectively and people not realizing it. I sometimes feel we are in a new dark ages with blood letting, trepanning, and curing demon possession.
