CAPTCHA is sort of a flawed concept in the first place. a machine to test if another agent is a machine. But I figure the future of this is give the test, but discard the answer, the truth is in how it is answered, behavioral analyses, see if their access patterns are human or machine like. A simple version of which is how fast they type, or speed items are clicked. A surveillance process that really creeps me out. I am undecided if it creeps me out more or less than fully automated agents spewing shit over the open web.

As a footnote i found googles recaptcha bitterly ironic, it was painted it in bright colors "this data assists in book scanning" or "this help our self driving cars recognize stop signs" but really designed to train models to do exactly what it's trying to prevent them from doing. and making life hell for the humans along the way. The modern single click version is doing behavioral analyses.
