Here's an idea. If a call is detected as a scam, provide an OS level hook for the call to be diverted to an app that can access an API. That'd be all that Apple and Google would do. At that point, App makers would get access to the call and could do a variety of things with it. So for instance, you might have a vulnerable grandparent you want to protect, so you install an aggressive AI screener app to handle these things. Or, you might just send a log of calls to a loved one. Or, you might send a transcript of that call to a loved one, or an AI, or both for protection. Basically, Google and Apple saying "Potential Scam" says to me that they can know when a call is risky. They need to do more with that and open up an ecosystem of defensive software.
