I was somewhat desultorily reviewing the information available on the web regarding terror birds, motivated by a program I'd been watching on the National Geographic cable channel. I'd seen the program--or one very like it--some time ago, and (typically for me) I was again doing something else at the same time. Consequently I missed a detail: the name of one of the bird's prey, described as a mammal unrelated to any now extant. This piqued my curiosity sufficiently that I made an attempt to identify it. In that particular quest for impractical knowledge, I have so far been unsuccessful.
However, in a process that's not entirely clear to me, I somehow came across the "technological singularity" concept. I vaguely remember having heard the term before, but if I ever knew what it means I'd forgotten, and further investigation led to mention of Singularity University. I'm sure that I hadn't heard of that before, and I'm surprised, since it's the sort of information that I usually encounter in the course of my regular reading and research.
So now I know, and I have something else to monitor and think about.
I also have the amusing realization that a quest for information about the Miocene led to information about the (near?) future.
