I am always confused when people compare LLMs with children - there is an obvious evolution of reasoning in children as the time passes by. This can be visible on a time span of months. Using the same analogy: I dont see this in LLMs, I can speak with an LLM months and if we dont release a new version it is the same. So they are not like children and I am not sure we really understand learning in children more so to the level that we can compare LLM with a child way of learning.
