Yet, we seem to be committed into destroying the entire system.
At least on personal devices/lines, everyone I've talked about it with now refuses to pick up any call from a number they don't recognize, which is really the only option when 2/3 of the calls you get daily are spam. Most just assume that if it's important, the caller will leave a message.
This is true, and also burned me last weekend. My dog set off my alarm system and the phone identified ADT as "potential spam" so I didn't answer it. The police showed up at my house. Fixed by adding ADT to my contacts, but the distrust is real.
I wish this was the case where I work. My boss answers every single call that comes in to her cell phone. Sometimes 15 a day. Then everyone in the office has to listen as she tries to interrupt the sales pitch and tell them "take me off your mailing (!) list."
And she's a millennial. I thought millennials didn't use voice.
It's far too early for carriers to block by default, but consumers should have the choice. If I could set my phone to give a busy signal to any caller not authenticated through STIR/SHAKEN, I would in a heartbeat.
And then pop-ups were replaced by divs, and adblockers got blocked by paywalls.
I don't think either problem has been solved yet.
You can have the "I don't care" attitude when you have one telephone number in your life. You have to care when you have a couple hundred thousand telephone numbers in your life, like I do, working for a Class 3 ITSP.
