> Why does a child need so much less data for “training” to reach “adult brain”? If we count all sensory input for years I do not think a child needs less data, but more. If, in addition, we consider that the child gets new data (decides new interactions) based on past data, there is an optimization in the child that the LLM lacks: the LLM cannot just decide to get some new data based on the data it just saw. It is stuck with the data fed to it for training.
