In mainstream understanding, there are three stages: aloof (classical autism), passive, and “active but odd”. The understanding ends here because nobody cares about adults, even if they kill themselves at a rate that rivals trannies.
Phase 1: Active but odd. I believe this is just how normal aspie children are, which is simply different because they are different. The so-called stages “aloof” and “passive” indicate brain damage, which may or may not heal as the child develops. This stage has been well described in many places. If puberty is somehow inhibited by factors like endocrine disruptors, the aspie remains in a facsimile of this phase indefinitely.
Phase 2: Adolescence. The body is physically maturing at roughly the normal rate, but the brain is diverging strongly from the mean. Male aspies get really excited about logic and categorical thinking (“now I can win all the arguments”), which manifests in different ways for MTs and TTs. MTs here acquire their interest in philosophy and political science, as well as their characteristic deep voices. TTs acquire their interest in devouring information at random and naming things, their odd hypoactive/hyperactive cycle, and the characteristic hyoid bone-influenced voice. If the aspie fails to become economically independent, they remain in this phase.
Phase 3: Independence. Outside the physical proximity of perceived strong male authorities, male aspies begin to manifest their secondary sexual characteristics. For MTs, this is ideological ambition. For TTs, this is their compulsive creativity. At this point the male TT becomes relatively fixed in place and has no interest in travel or moving (“I could read a book for that”), in stark contrast with the females (NB: the Faroe Islands are a holdout of TT society). If the male aspie fails to marry, they remain in this phase indefinitely.
Phase 4: Monogamy. When an aspie is getting laid regularly, they begin to be interested in accumulating wealth and building up their house and estate. They will begin to make weekly forays to bond with the community and even become interested in going to church, despite the weak allegories and imperfect theology :-). They become interested in collective action, such as mammoth hunti—I mean business. Strictly business. Weird, my genetic memory was acting up for a second.
Phase 5: Acquiescence. Old age. I have no context to work with here because I don’t know any crazy old people and I have no intuitions to work with. If it were me, I’d use the extra time to write books.
