If it beats the vast majority of botters it’s useful

I'm not even sure that chat GPT is really the answer to these kind of captchas. I figured people would probably do a little bit of custom programming to quickly answer the question and then perform the action.

But if everybody writes their own custom challenge, now that's a lot of targets. Whereas right now we've already trained the AI to identify all the stoplights, and that kind of captcha is ubiquitous. They just have to solve it once and then a whole bunch of websites are vulnerable.

And most websites aren't actually that high value, for example mine. Is anybody going to spend the time reverse engineering a simple captcha just so they can post comments to my blog that no one reads? :)

But if I used something off the shelf that they already have a solution for, then sure they would.
