I envision the app on the phone that implements AI secretary and answers unknown phone numbers on my behalf, and calms down calling party with various measures, with sort of captcha of various degree of offense. This will hold them off until they find a workaround.

The Pixel 8 does this, it's called "Call Screen" and since getting it I never receive unscreened calls from outside my contact list. It's been very nice to have.

I have such an app. It's called RoboBlocker. I used to use a different app called RoboKiller, but recently switched. Both work basically the same way. They automatically block known spammers/scammers and screen the rest.
