I think when I first realized that something interesting had happened was probably in 1994. There was a 25th anniversary of the ARPANET celebration and... somebody asked the question, 'Where did email come from?' I remembered that I had done this little program back in 1971. People looked back and nobody could find anything that predated it.

The story I get the biggest kick out of is when my name and e-mail appeared on 'Jeopardy' a couple of years ago. My mother was a faithful viewer, and she said she was happy that they finally had an answer she knew the question to.

By irreducibly complex I mean a single system composed of several well-matched, interacting parts that contribute to the basic function, wherein the removal of any one of the parts causes the system to effectively cease functioning.
