A human child not taught literally anything can see some interesting item extend a hand to it, touch it, interact with it. All decided by the child. Heck, even my cat can see a new toy, go to it and play with it, without any teaching.

LLMs can't initiate any task on their own, because they lack thinking/intelligence part.

This to me overstretches the definition of teaching. No, a human baby is not "taught" language, it learns it independently by taking cues from its environment. A child absolutely comes with an innate ability to recognize human sound and the capability to reproduce it.

By the time you get to active "teaching", the child has already learned language -- otherwise we'd have a chicken-and-egg problem, since we use language to teach language.
