Treat everything you post online like a postcard.
Assume all encryption can be or will be broken at some point.
The primary purpose of the internet has been surveillance.
Child safety begins at home, with the parents.
If that relationship becomes compromised, by divorce spousal abuse etc., it is unlikely to be fixed by the "system".
I agree that online information should be considered public, in general - since there is no foolproof digital security. I'm not sure the purpose of the internet has always been surveillance, though, since it can clearly be so many things to so many people. I'm sure there were some people who wanted it for that purpose all along though, for sure.
To be fair, the Internet can be used for almost everything, I would argue its been quite effective at behaviour modification.
I have to disagree the primary purpose of the internet is surveillance. If you simply look at the money, the primary purpose of the internet is pr0n.
Parents take note.
Adult entertainment is one of the best ways to lure the masses into the surveillance system.
Power and internet access will be one of the last services to be cut.
I am LOLling at the thought of tens of thousands of boys adjusting their laptops so their surveillors are sure to have a clear view while they fap.
Ah love!
There is a black mirror episode that shows exactly what you describe.
(spoiler alert, it doesn't end well)
