An aspect of our discussion should include the development of the brain in current human adolescents and how it allows for full development of personality and of course the full development of the s/s/c:

From my training I know, and we have discussed in the past, that the human adult does not have a completed pre-frontal cortex until age 25. A person cannot fully evaluate his/her decision making particularly as to risk taking until that point. But the brain is fully enlarged as is the skull by age 16-20. What is not complete until age 25 is the complexity of the neuron network and the ability to use that network to its full capacity. Thus a fully developed and functional s/s/c must wait for the underlying biological development. It is current theory that the adolescent must wait until his brain is ready for him/her to think and made judgments at the adult level.

This fits my theory that complexity (size with complexity) must precede full thought/concept capacity. Size/complexity first, concepts/artifacts second, as we see in our adolescents' development
