I am confused about the value of the new Call Screen feature that Google plans to add to Pixel phones. I assume the primary purpose is to screen telemarketing calls, but doesn’t the very act of answering the call provide a signal that the number is valid? I was under the impression the best thing to do with telemarketing is to not answer the call.

Right now, if I get a call that I don’t recognize, which is most, I decline the call. Period.
