Another interesting phenomenon of the iPhone and iPad era is that we are being transformed from producers of content into consumers. With my BlackBerry, I probably created as much data as I consumed. It was easy to thumb-type long explanations, directions, and even jokes and observations. With my iPhone, I try to avoid creating any message that are over one sentence long. But I use the iPhone browser to consume information a hundred times more than I did with the BlackBerry. I wonder if this will change people over time, in some subtle way that isn't predictable. What happens when people become trained to think of information and entertainment as something they receive and not something they create? I think this could be a fork in the road for human evolution. Perhaps in a million years, humans will feel no conversational obligation to entertain or provide useful information. That will be the function of the Internet. Someday a scientist will identify the introduction of the iPhone as the point where evolution began to remove conversation from the list of human capabilities. And when the scientist forms this realization, he won't tell his spouse because conversation won't exist. He'll put it on the Internet.
