Pretty much this. Google's captchas some years ago were all about pointing out road related things, like semaphores, other cars, buses, etc, because self driving AI was just around the corner.
hCaptcha, the one in this image, is literally using us to train/refine art prompts. I've had a number that asked me to choose the pictures that showed a "whatever", with the 9 images for clicking being obviously AI genned. Sometimes, it accepts 2 rights and 1 wrong.
