Disclaimer: I've been involved with the project (in a tiny way), and am a fan.
1. English is taught widely, and they need it anyway.
2. The lexicon to master is pretty short.
3. Kids naturally learn words. Say, with moderate interest in K-pop a European teen can remember Korean names, sometimes even in Korean script.
4. "For" in programming is not the same word as "for" in natural language. You may be under illusion that when it's in a local language, it will be easier to digest, but it's not. You need to explain its separate meaning anyway. And when you did it not in Programming English - sorry, you simply missed the opportunity. You spent roughly the same amount of time to create a redundant word-slot in student's memory.
5. "Tried" is not a valid metrics for success here. One could as well offer free cookies, and number of tries would be growing. But that elephant in the room will look at us without approval!
I have doubts whether the gradual language is confusing or sensible to the average brain. Only time and competition in these kinds of educative tools will tell.
But, there is one thing I'm very sure of: the more kids that get to experience the joy of creatimg something by programming, and the more kids that get to experience the feedback loop, the better!
A key insight. Feels like the usual human confusion over activity and output. Activity metrics bias for participation / attention at the top end of the funnel, whereas Output metrics assess the end: the quality & quantity of production. The first is visible, immediate, plays to human bias, whereas the second is much farther off and usually less interesting to the general public.
Applied to kid coding, adults like seeing many kids doing work socially, whereas the few kids who stick with it aim for genuine, even selfish, creation.
It's not a bad initiative, just one that seems to cater mostly to the ideals of the teachers and the parents.
AI
The best learning tool, "stepping stone" for kids. And they're already familiar with it when cheating on their homework.
I wasn't saying that AI is not here. It is, and it is very important. Happy to have a proper discussion about that.
If this were your intentions, you would have done exactly that. So far you have produced 0 statements on AI beside empty affirmations "AI is very important." We can do better than that on HN.
