[C] Interpreting that as asking whether this thing has always existed: YES. [B] NO. But the audience, who applauded the previous question, make appreciative noises.
[B] NO. [C1] YES is the useful answer. A strict and slightly tedious reading of your question could yield the answer NO. [C2] NO. (but good to know I got your logic question correct!) [R] YES, it seems, but probably not significantly for a very long time.
This AVMA seemed like an interesting idea when I thought of it, but in hindsight probably was a mistake. :) And my commitment to exemplifying the AOTC with my answers has left me unable to communicate any nuance in my responses. You are all being too specific; the AOTC is a general (and very simple concept) that is a feature of many of the guesses you have collectively made.
