If you're talking about CAPTCHA solving as a service, that already exists, and the cost is measured in mere dollars per thousand CAPTCHAs solved.
Why the "if"? Of course, I was talking about captcha, is the regex parser in your brain case sensitive?
No need to resort to ad hominems; I just wasn't sure what you meant by "CAPTCHA as a use case" and wanted to point out that it's possible to do much better than $0.1/CAPTCHA solved.
that's a great idea - I put together one example for getting an MFA code for a website, but the captcha thing "pull a human into a web session" is something I've wanted to play with for a while
