More countries should ban social media for children and enforce it. I made the mistake of optimising one of these social media sites with reinforcement learning (RL) for user retention several years ago. I realised later that I had made a mistake and I strongly regret it. Humans are no match for super intelligent machines grabbing their attention. While it is true that YouTube, TikTok, instagram, Snapchat, etc, can offer valuable information, such tools are optimised to keep users engaged. Slop, brain rot, anything RL can do to catch kids attention is what these companies promote. If you work at one of these, please don’t optimise with RL or LLMs to keep children hooked. You have a say at your org because the most important and valuable ingredient of any tech company is its workers.
