Interesting reversal of the "think of the kids" argument, though: think of the kids who could have used their phones to document their mistreatment at the hands of alcoholic perverts.
I'm reminded of the way that universally carried high resolution cameras made UFOs and crop circles disappear, but police suddenly became a lot less trustworthy.
The abuse question .. well, "social justice" is a term that starts fights, but there have been a lot of people who've been able to get some sort of justice only because they raised their cause on social media, having been ignored by the authorities. #MeToo is probably the big example, culminating in the Epstein revelations.
Age 16-17 is very different than Ages 5-10 for kids to carry a device.
The former is no issue. I just don't think the author's take is nuanced as they think.
Kids (Age 5-13) safety is of ultimate importance. Devices, independently are also a major issue in schools. Social media use of bullying also is a major issue. To the point they are banned.
Reminds me of the "good guys with guns" narrative tbh. Being able to document such transgressions is not enough of an argument to do a mass rollout of ad display technology IMHO.
