I've long noticed this phenomenon in my own life. I can't remember a single
friend's email address.
Hell, sometimes I have to search my inbox to remember an associate's last
name.
Friends of mine space out on lunch dates unless Outlook pings them.
And when it comes to cultural trivia — celebrity names, song lyrics — I've
almost given up making an effort to remember anything, because I can instantly
retrieve the information online.
In fact, the line between where my memory leaves off and Google picks up is
getting blurrier by the second.
Often when I'm talking on the phone, I hit Wikipedia and search engines to
explore the subject at hand, harnessing the results to buttress my arguments.
