How you make it in this world, for the most part, depends more on what you do as opposed to whether people like or dislike you. In order to produce a successful life, one must find ways to please his fellow man. That is, find out what goods and services his fellow man values, and is willing to pay for, and then acquire the necessary skills and education to provide it.
As I became a creature of the empty tunnels, survival became easier and more difficult all at once. I gained in the physical skills and experience necessary to live on. I could defeat almost anything that wandered into my chosen domain. It did not take me long, however, to discover one nemesis that I could neither defeat nor flee. It followed me wherever I went - indeed, the farther I ran, the more it closed in around me. My enemy was solitude, the interminable, incessant silence of hushed corridors.
The ways in which acquired savants show up are usually the same ways that congenital, or non-acquired, savant syndrome shows up. They tend to show up in the same areas: music, art, math, visual, spatial skills, and calendar calculating, although calendar calculating probably isn't quite as prominent in that group. They tend to show up quite quickly, or sort of explode on the scene and they then tend to have an obsessive sort of forceful quality about them in the same way as savant skills. So they tend to show up in the same ways.
Childhood is analogous to language learning. It has a biological basis but cannot be realized unless a social environment triggers and nurtures it, that is, has need of it. If a culture is dominated by a medium that requires the segregation of the young in order that they learn unnatural, specialized, and complex skills and attitudes, then childhood, in one form or another, will emerge, articulate and indispensable.
