How many technological advances have happened since the last brood of cicadas emerged seventeen years ago?
It's strange how the Internet, this large 800 pound gorilla, somehow just sat down in our living rooms, our basements, our offices, without most of us even realizing it was making itself at home. It was gradual enough that it all seemed rather natural.
Now we take it for granted, and we communicate on a daily basis with people (many of whom we have never met), and possibly even post our stray thoughts for strangers to read.
I did a search on Usenet for the earliest post discussing cicadas and dug up one from 1990 in the alt.horror group:
Ecology of Alien(s)
What will the world be like the next time the cicadas emerge?
