I don't really get how this stops captcha solving as a service, which is the actual way that scaled recaptcha solving is done? Those things are incredibly cheap and are staffed by humans anyway. Instead of selecting grainy busses, they will just scan the image with their phones.

They'll need a lot of google-certified phones then. And each phone will only be able to do so many verifications until the unique, cryptographically secure ID gets banned by Google.

Google already killed SMS verification market specifically for Google accounts because they reversed the verification from receiving to sending the SMS. Almost a year after, no SMS verification service that made a killing on this is offering an alternative.

So yes, this will definitely affect the captcha solving services.
