Posting it publicly is also helping him learn about people - we talked about how no matter what some percent of people won't like it and may even say it's stupid, but that will always happen and it's still worth creating things anyway.
Humans learn mastery by doing, not by watching.
I suppose it comes down to whether the most important skill for your kid is to give instructions, or whether it is to actually read and write.
For reference, my kid only just turned 6, and is at the level of reading books without pictures. I'm kinda proud that he reads better, faster and with more retention than kids aged 9, and it didn't come with the ease[1] that "nerding out" on Claude came to your kid.
The question you gotta ask yourself is this: is a skill that takes a 7 year old a day to master really going to make him more valuable than a skill that took a 6 year old 2.5 years to master?
The 6yo who can read can easily do what your kid did, but your kid can't easily do what the 6yo can.
From another PoV: how valuable of a skill do you think "prompting" is when a 7yo who hasn't mastered reading can master it?

[1] I started a daily routine when he was 3.5 with the DISTAR alphabet. We did the routine every day, whether it was christmas, or his birthday, even on vacation. Same time, every day.
I am extremely excited that your kid is able to do this, and even you sharing it now here isn't like "my child's game is the best game ever look at me" it's thoughtful commentary on the post I've written.
Even if you had shared a separate post on HN proper like "LLMs are enabling my child to build earlier and become involved in tech" or something that would have had thought behind it on why its interesting to other people, in considering other people you're acting in good faith.
My overall point isn't that LLMs generating apps are bad it's that we should consider why what I'm showing to someone else would matter to them in the first place, which you did here :)
Which isn't diminishing the authors of that prior work either, those same individuals with these new tools would have been able to do more too.
Of course he will, just not well. The point of the GP is that he doesn't need to learn anything because the AI can understand his verbal instructions.
