The Made by Google Podcast featured the group product manager for the Phone by Google app. According to the product manager, Google is working to resolve the issue of unwanted calls.
Conversational AI was mentioned as a possible solution. In terms of creating this protective and helpful layer at the front of every incoming call, multi-step, multi-turn conversational AI could open a lot of interesting doors. While the Pixel’s Call Screen feature already employs AI, it appears that Google intends to enhance it further with additional AI.
