Feels bad to say but not posting photos due to these fears seems pointless. Your kid will get tagged and associated to you regardless of what you do. There are that many surveillance cameras around that unless they will live under a mask their face is out there. At best you'll be able to prevent your friends making memes / AI videos with your baby's face. But, more sophisticated actors have what they need.

Agree. I think it comes down to the level of sophistication to your point. Technology will only get easier to use and things will get cheaper and easier to access. We know big tech and intelligence have them. AI and cheaper tech gives less sophisticated people access to it.
