For my young kids ( under 10 ), I am very strict on what they can see and do online. Screen time, CleanBrowsing, and app restrictions enabled.
For my teenager, it is a bit different. More conversation, more privacy and more spending time teaching her about computers, security, privacy, etc. She chose to install CleanBrowsing, an ad blocker, all on her own to protect herself.
It depends on the reason to learn a new language. Once you know a few languages, you generally only learn a new one if you are trying to solve a specific problem that it can do better.
