@w7voa My cynical suspicion about CAPTCHAs has always been that the companies are actually using some fraction of them to harvest AI training data. (That is, say 10% of the time they are not testing you, they are using your labor to create labelled images for training future AI systems.) Others have made the same argument too: https://www.techradar.com/news/captcha-if-you-can-how-youve-been-training-ai-for-years-without-realising-it
