Is it true that it's bad for learning new skills? My gut tells me it's useful as long as I don't use it to cheat the learning process and I mainly use it for things like follow up questions.
It is, it can be an enormous learning accelerator for new skills, for both adults and genuinely curious kids. The gap between low and high performancer will explode. I can tell you that if I had LLMs I would've finished schooling at least 25% quicker, while learning much more. When I say this on HN some are quick to point out the fallibility of LLMs, ignoring that the huge majority of human teachers are many times more fallible. Now this is a privileged place where many have been taught by what is indeed the global top 0.1% of teachers and professors, so it makes more sense that people would respond this way. Another source of these responses is simply fear.
In e.g. the US, it's a huge net negative because kids aren't probably taught these values and the required discipline. So the overwhelming majority does use it to cheat the learning process.
I can't tell you if this is the same inside e.g. China. I'm fairly sure it's not nearly as bad though as kids there derive much less benefit from cheating on homework/the learning process, as they're more singularly judged on standardized tests where AI is not available.
