Captchas original purpose was transcribing books, no. And then Google used their version for doing house numbers. (I've a feeling there was some other common type I saw, but can't recall). Now, they're used to train vehicle AIs and map road features in USA. Less happy about the latest one but the book transcription and map correction were good as I benefited from both those projects (used the tools).

ReCaptcha's original purpose was transcribing books. We had captchas for several years before anybody got that idea.

  Ah yes, thanks for the correction - I think they've become synonymous for me as I don't ever see non-'photo interpretation' captchas.
