Interesting thought but is it that the sigmoid curve can represent the developments in SW and/or HW? To reach the saturation point we need to be able to define

Interesting thought but is it that the sigmoid curve can represent the developments in SW and/or HW? To reach the saturation point we need to be able to define a system up to the point where there are almost no more unknowns (variables), no? I am thinking that this probably isn't possible in the context of {SW, HW}.
