That will crash inevitably into the 'lets make the trash can tough for bears. oops we also made the trashcan tough for 10% of humans'. (is there a name for this phenomenon?)
it's an optimization problem, with context dependent levels of true negative, false positive acceptance criteria

surely you cannot have a million Bangladeshi humans reading captcha via API due to the realities of eligible population / cost at scale, so it still does function for most use cases that want to leverage such "automation".
CAPTCHA is really just a proof-of-work system, it just happens to use problems that are easy for humans but hard for computers. It has never proved that the request is a genuine human request, it just proves that a human was in the loop somewhere; that human can just as easily be a Bangladeshi employee of a CAPTCHA-solving-as-a-service provider who is accessed via an API call. If we run out of problems that are easy for humans but hard for computers, we can fall back on the infinite set of problems that are just hard.
