This AI debate is hilarious. Especially from a privacy standpoint, because if anyone were all that concerned about their privacy, they wouldn't be posting sensitive stuff to things they don't control, if at all.
Add to that society trends towards an increasing population, societal pressure that frowns on any talk of how to stabilize or even decrease the population, and our ever increasing reliance on various black boxes that we dont even begin to understand, and you can see we're heading in a direction that goes against privacy whether we want it or not.
Easier to encourage people to make the conscious effort to not post what they dont want public than it is to change all the platforms involved.
