How well can your personal information remain personal, and not be
used for e.g., AI training
purposes? Child privacy is societally considered quite important.
It is usually done by "information asymmetry" (in a good way?)
A sign of power and uncertainty, and also is seen as a bit unfair, but
it needs to remain for the sake of functional systems and human privacy.
It's now become company jargon, however, most don't read Privacy Policy (and
lie about it). Your information may be sold to third parties. :)
Pragmatically, if online, most people bypass
it. For instance, forced ID verification causes lots of public relations
damage and privacy concerns if information is leaked by other
people.
However, even out of that, having a set number, arbitrarily, might be a
bit unfair. As humans do mature at different rates. Still, it can be a
shortcut, as maturity is usually hard to know.
Technically, the best thing is to store everything in your hard drive, stop socializing, and stop posting on social media, and STOP USING GOOGLE CHROME! (I wouldn't have made this Wiki if I cared fully about my Privacy!) But, I know that's torture for most of you, psychologically speaking. So just minimize how much you do it, and selectively choose what information to let others see.
The media, yet again, posts about the worst cases, for instance,
leaks, like credit card mass-compromises.
But general philosophical ideas should be fine for the
public to read. Because I doubt anyone would use such an intellectual
for a malicious purpose! What a relief.
