The real risk is the TFR never rises and population drops until complex society cannot be maintained. Or perhaps some weird minority with higher TFR takes over the world, what I call the "Amish Scenario".

Are you talking mainly about demographics? Like not enough working age people and too many older people?
Yes, and also that if the population becomes small enough it becomes impossible to sustain an industrial society due to lack of scale.
Isn't most of industrial society really just trying to deal with the problems of having to sustain so many people?
