The CAPTCHA Toll
A checkpoint where humans prove to machines that they are not machines will keep the machines out.

Begin with the surface inversion, strange enough on its own: billions of times a day, humans petition machines to certify their humanity — a Turing test administered in reverse, by the party that was supposed to be taking it. Then the Dramatic Irony layer: reCAPTCHA’s elegant design put the toll to work, and the workers didn’t know for whom. Every squinted-at word digitized an archive; every tagged traffic light trained a vision model. The audience (the system’s designers) knew what the characters (all of us) did not: the test was also the curriculum.
The closing Situational Irony turn completes it — models trained on that harvest now solve CAPTCHAs faster and more accurately than people, so the checkpoint increasingly filters for machines and against the humans it was built to admit. A gate that taught the barbarians to forge its keys, using toll receipts.
