I do not recommend the use of any commercial LLM or open weights imitation to be used by anyone unless they are resistant to gaslighting. No matter the age. Prompt engineering is training specific and the problems with LLMs are caused in the training.

IMO the bigger issue is not learning how to prompt, it's learning how to evaluate LLM output.

If you can tell whether the output is good or bad, and especially if you can tell why it was good or bad, you can adjust your prompt accordingly.

To know how to evaluate LLM output, you need critical thinking, domain experience, taste, and agency (to know what you are trying to accomplish). LLM does not do those things for you.

Screen time is detrimental on the developing brain. The screen flickers and emits bluelight. It is making them sick and changing their behavior.

You said it yourself "excessive use of AI will cause cognitive atrophy”, whatever you teach your 11 year olds, aim to do it with minimal screen time, they get enough.

Do you use lamps to light your classroom? The overhead lights are toxic...

Technology should always be used in a balanced way; as long as it is used properly, it will help the progress of whatever we want.

Prompt engineering is a dumb phrase. What people should learn that will help with using LLMs is how they work, are trained, and why they fail.

Then you remove the magic and that helps with the next thing. How to evaluate output. LLMs are not great if you have little knowledge of the subject. They are far more useful if you are a subject matter expert.

The problem with AI is they promises the hype machine has made. They are writing checks they can't cash. They are useful but not magic. Not yet. It's an evolution not a revolution

I was thinking and talking pretty much on the subject some time ago. From my point of view, kids should have limited screen time and no access to social media - at least not to the brain rotting part of it. Same goes for LLM. They need to learn how to do things, correct, but...for the moment they don't need to learn how to prompt an AI to do those things for them. This is brain washing them in time. In my opinion the sooner they will start using LLMs, the quicker their brain will die from a creativity and logical point of view. And I would tend to say the same will apply to their ability of crafting stuff. What they really need to learn is to evaluate what the AIs/LLMs produces and sets loose in the online. The mainstream social networks are already full of junk and AI bullshit and promoting stupidity mostly....
