Given the rate of improvement wrt to llms, this may not hold true for long
The rate of improvement with LLMs seems to have halted since Claude3.5, which was about a year ago. I think we’ve probably gone as far as we can go with tweaks to transformer architectures, and we’ll need a new academic discovery which could take years to do better
It's been my experience that LLMs are only better than me at stuff I'm bad at. It's noticeably worse than me at things I'm good at. So the answer to your question depends: can your child get good at things while leaning on an LLM?
I don't know the answer to this. Maybe schools need to expect more from their students with LLMs in the picture.
