If I remember correctly, Google’s CAPCHA’s test isn’t in correctly identifying images, but the behavior of the runtime system (mouse jitter, for example) while the capcha is presented to the user. The image identification was not the real test and serves as training data. It has been like that for years. (But with agent-based behaviors from say, Q*, mouse jitter alone won’t help; there are probably other signals like fluctuation in cpu or battery life expenditures)
You could already see the writing on the wall with image identification years ago, when the obscuration techniques became more elaborate. It was an arms race. I was having trouble with them. I can see less technically inclined being able to use them. I imagined how much worse it was for people with color blindness, disabilities, or people forced to use them at public library computers because that is all they have.
Open source capcha projects have either not been clued in, or don’t have the resources to pull this off. Google didn’t just switch out which signals they tested, they also wrote an obfuscating virtual machine executing within the browser environment (if I remember that article taking about this correctly). That was years ago and who knows what they do now — for all we know, the “byte code” running the test is now a neural net of some kind.
