I've seen a couple sites that do this. One of them just asks for the square root of -1!
And sure, qntm.org isn't nearly as big a website as HN, but I concur that this isn't likely to be super-difficult. The wide use of recaptcha seems like mostly laziness; most websites aren't big enough to get targeted attacks.
