Tell me: why are these algorithms suddenly okay when the victim turns 18?
They are bad for everyone and if you’re willing to regulate them, make them illegal to be used on anyone.
The idea is that underdeveloped brains are less capable to make correct choices. Why do we suddenly make people responsible for their actions at 18?
Just from this article it's not clear if the methods like endless scrolling or "watch next video" are going to be regulated based on user age or not.
It just says the platform who use such methods, often target kids.
Same as for the cigarette: it's a lot easier to regulate stuff for kids, because we as a society tend to agree that they need to be protected. Much harder to do with adults, because it is much less of a consensus.
Because, in general, we see adults making bad choices as a price worth paying in a free society, but we recognize that children lack the maturity and judgment to make those choices for themselves.
Most adults also lack the maturity and judgement, but allowing adults to make bad decisions is usually less dangerous than giving someone else the power to decide which decisions are too bad to permit.
Smoking has entered the chat
Because I'm an adult, rather than a sheep for you to control, and I much prefer being shown things in my interest (via recommendation alg) rather than things in the general populations interest. In fact, I wish I could upload my own recommendation model to all the social media, to curate it better, and put some black holes near topics I want to avoid, with the option to fuzz it a bit for exploration.
