When I used phone books:
- My banking accounts weren’t globally accessible
- The data companies collected about me was effectively non-existent, and wasn’t globally accessible
- My phone had no information about me, didn’t know my minute-by-minute whereabouts, and if somehow you organized a DDOS against it, I could just take it off the hook and walk away
- My employer didn’t have social media, and couldn’t be bombarded with accusations against me
- Swatting was less likely, because there weren’t 8 billion people with easy access to my data
I could probably go on for a while. None of the above is me “opening myself up” except by virtue of owning a smartphone, which is difficult to avoid.
