Yes, I thought that and then even checked the article to see if that point was noted.
For full context, here's the etymology from Wikipedia:
The terms "bug" and "debugging" are popularly attributed to Admiral Grace Hopper in the 1940s. While she was working on a Mark II computer at Harvard University, her associates discovered a moth stuck in a relay and thereby impeding operation, whereupon she remarked that they were "debugging" the system. However, the term "bug", in the sense of "technical error", dates back at least to 1878 and Thomas Edison who describes the "little faults and difficulties" of mechanical engineering as "Bugs".
I was unaware of the Thomas Edison reference. Somehow, it seems unlikely that he coined it, so perhaps the history goes back even further.
