Well, yes, it is. Kids who used calculators to cheat with basic arithmetic will often struggle with learning more advanced concepts later on because they didn't get a "feel" for numbers, and I strongly suspect the same will happen with kids who start using LLMs before they know how research works.
It is totally appropriate to use calculators when you can already have an intuition for small numbers, and in just the same way students should learn to use LLMs, but only when they already know how to write and think and research stuff. Curriculum needs to adapt to this quickly, otherwise we will end up with a generation that outsources all their thinking to techbros.

This isn't how anything ever works, especially with bigots.
