Correcting the Record: Why Common Computing History Stories Are Wrong

The article debunks widespread misconceptions about early computing, starting with the origin of the term "computer bug." While a moth was famously taped into a Harvard computer notebook in 1947 with the caption "First actual case of bug being found," this was actually a pun—the term had been used since at least 1878 by Thomas Edison to describe technical problems. The article also challenges the notion that the Y2K concern was overblown, noting that the U.S. spent approximately $100 billion to prevent major disruptions, suggesting the preparation was justified.

The term "bug" has a documented history stretching back decades before the famous 1947 Harvard incident. Thomas Edison was already using the word to describe mechanical and electrical faults in his work during the 1870s, establishing the terminology well before computers existed. The moth discovery became culturally memorable partly due to Grace Hopper's prominence in computing circles, leading many to mistakenly credit her with coining the term or assume the incident marked its origin.

The Y2K preparation effort, while resulting in no catastrophic failures, still produced measurable consequences. Despite $100 billion spent on remediation in the United States alone, documented problems did occur afterward, including nuclear reactor shutdowns and other system failures. This suggests the extensive investment successfully prevented worse outcomes rather than addressing a nonexistent threat.
