Yeah, I was thinking about that when I posted-- the term "stack" is also still very much embedded in the jargon of the industry (and beyond). Probably most people under 40 don't realize that it refers to punched cards.

Fun fact: for years and years, I was with an auto insurance company that used punched cards for billing-- until about 1990, when they upgraded their servers. I was forever charmed to get my billing statement with a detached punched card to return with my payment, and a bit wistful when they finally went modern.

Schrödinger's cat walks into a bar. And doesn't.
