“Computer” meaning a mechanical/electro-mechanical/electrical machine wasn’t used until around after WWII.
Babbag’s difference/analytical engines weren’t confusing because people called them a computer, they didn’t.
“On two occasions I have been asked, ‘Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?’ I am not able rightly to apprehend the kind of confusion of ideas that could provoke such a question.”
- Charles Babbage
If you give any computer, human or machine, random numbers, it will not give you “correct answers”.
It’s possible Babbage lacked the social skills to detect sarcasm. We also have several high profile cases of people just trusting LLMs to file legal briefs and official government ‘studies’ because the LLM “said it was real”.
And what I mean is that prior to the mid 1900s the etymology didn’t exist to cause that confusion of terms. Neither Babbage’s machines nor prior adding engines were called computers or calculators. They were ‘machines’ or ‘engines’.
Babbage’s machines were novel in that they could do multiple types of operations, but ‘mechanical calculators’ and counting machines were ~200 years old. Other mathematical tools like the abacus are obviously far older. They were not novel enough to cause confusion in anyone with even passing interest.
But there will always be people who just assume ‘magic’, and/or “it works like I want it to”.
