This must be the elephant in the room. Traditional telephony has become dominated by bad actors. They hit a critical mass and now my phone app is a waste of space.
I'm slowly realizing that this is because apparently people are inundated with spam calls? I think I may have received one solitary spam call in my entire life. I can't really account for the discrepancy
I wouldn't say I'm cautious, it's simply that if it were important, why would you call?
I basically consider phone calls as unimportant as paper letters. Check in on them every few weeks.
Claiming this in general is trivially rebuttable by the fact that I know many people who feel precisely the opposite: if it's important you call, if not you text.
If anything, that view is less irrational than yours: a mode of communication that's immediate, loud, sustained for many seconds, and hits a device that most people have on them constantly fits far more easily with realtime urgency than any other mode of communication.
On top of THAT, there are still stupid legacy systems (that are nonetheless important) that use old forms of communication. My insurance was cancelled while I was on a backpacking trip and they called me and sent me a letter without bothering to send me an email. The fact that Blue Shield are fucking idiots doesn't change the fact that I was without proper medical insurance for th rest of the year (due to ACA enrollment limits). I could easily see the same being true of phone calls.
It seems to me I can either call, which most likely causes a loud and persistent ringing noise that signals "someone wants to talk to you right now, please pick up the phone". Or I can send you a text which will make a quick beep on your phone and then go away.
I actually adopted the "don't answer the phone" strategy about 20 years ago, when first I got voice mail. I wish everyone had. But nowadays I don't even listen to my voice mail.
I have 27 from random numbers/places that I know from experience are scams. This is a US number.
If you find your life lacking opportunities to get in to obscenity shouting matches with random con artists, it is great! Otherwise, not so much.
However, in both cases, it was nearly 100% spam. I talk to family via video chats, and friends via facebook, hangouts, whatsapp, etc.
Frankly if the telephone app on my "phone" stopped working I wonder how long it would take me to notice.
